@@thecawckiestking yes he seems honest but also unethical. This dog was trying to bite him when he first got it. Is it a surprise this happened? You shouldn't rehome human aggressive dogs.

[@thecawckiestking]

@@OptimusPrime-dz9md He got the dog from a place that explicitly sells these dogs for the purpose of protection, police, and military work. This isn't a pet dog and I doubt he sold it to anyone as such. He "rehomed" this dog to someone who explicitly had experience with Dutch shepherds. Whether or not its "unethical" largely depends on where it goes and what that person's needs are, private information which none of us have and which it isn't our business to have. Would it be "unethical" to sell a human-aggressive dog to a private compound with barbed wire fences and "no trespassing" signs everywhere for instance, where the intent is to keep people from breaking in? Or to someone in the military who plans to take the dog to a war-front? Context is quite important to whether or not we put the "unethical" stamp on the, quote on quote, "rehoming" of these dogs. Its not as though he sold it to your average white picket fence family with a gaggle of hyper five year olds living in Beverley Hills. And there are plenty such people who pick up much worse dogs from your every day rescue shelter. You can find them all over youtube, crying about how their vicious dogs have "never hurt anyone" after they made the news for their dog attacking/killing someone.

I'm sorry. If a dog is so unstable that it will bite unprovoked, that dog should not be used for breeding. You say this is common in Dutch shepherds, but that means the behavior isn't being bred out. Mental stability is 100% non-negotiable.

This is too common for malinois and Dutchies. I think it's just what happens when you breed a dog to have an obsessive, compulsive addiction to biting things. It's like doing drugs to them, and sometimes the impulse control slips and they end up biting something they shouldn't. Either that or Mace felt he could assume the alpha position over his owner and took his opportunity. Just my theory, anyway, my trainer has a mali that sadly does the same thing that Mace did. Multiple times, with no warning and sent several to the hospital. It basically means the dog stays in the kennel until it's time for training, which thankfully works for their situation.

Also, such an informative video on the tools you use! Not that it's necessary for the average owner but SO fascinating and totally useful for those dealing with dogs like this, or if their own dog even has a few quirks. I am very grateful you shared. Curious, when leaving the crate, he's very impulsive. Is that something you work on? Or the idea is just to get him out? Any cues you can use to make him wait? He's so aroused when you open it. Curious about thoughts on curbing that arousal? Or is that just because he had been couped up a few days and pent up energy?

One thing Mr.Haz is forgetting to mention is that redirecting for no reason at all its not a sign of strong character,it actually shows weakness in the dog ..Real dominant dogs like to challenge the handler from time to time but key word is challenge in appropriate times,dogs who bite out of nowhere when not even training are just nasty dogs...this a common issue why rotts are not used much nowadays for police work,all rank aggression more then anything else...There are way harder dogs out there then Mace that if you train em fairly and wont back down when they test you and uve got good reflexes that u will probably never ever get bit by them...Also redirecting to the handler its not the only form k9 shows dominance,also willingness to not obey repeatedly (in later stages of training) is a sign of dominance .A dog can be hard as granite and not be nasty..... Side note:Dutchies are notorius for chewing up theyre handlers in many dept while having 50/60% of work performance of a good mal/gsd ...theyre notorius for redirecting in operations too a lot..many seem to not have the best nerves..

[@TDCIYB77]

Dont want to make your relationship with your dutchie sour, but as Haz said: There were no indications prior to handler agression, and all other indicators looked normal. Mace too seemed to have a deep bond with both Haz and the new handler.. And here we are. Its not a common thing, but with this breed you just need to be on alert, and ready all the time. It is no coincidence the breed has the repupation it has, and that allmost all experienced trainers dont recommend them at all as pets, even to very experienced owners, other than for professionals like Haz who also love the thrill of having such a primal dog. They are bred to bite, to be neurotic and full of drive. I would be cautious, and i am a 220 pound man, and even more as a Lady as Haz said, no offense. Likely you are right and have won the genetic lottery, and as i said, those unprovoked attacks are uncommon. But i would still be consious of the possibility. It is IMHO the most dangerous and demanding breed, beside the usual suspects of Pitbulls and other dogs bred for dog fighting.

[@jfkst1]

@@TDCIYB77 I find the label "Dutch Shepherd" questionable on Mace as he is a KNPV dog that is very unlikely to be a pure bred Dutch. Particularly at his size where I'm guessing he's 95+ lbs. So that is probably a misnomer at best. I work in security consulting and place dozens of handler teams in working roles every year. I have nearly always predicted when a dog would be questionable in the work environment or with the handler beforehand. Haz said as much about Mace many times in his videos.

[@fredericlinden]

I am not familiar with the breed, however I think it is clear, as you've pointed out, that his primal instinct is very deep and can only be dealt with with STRICT and constant obedience. Just the fact that he wants to get out of the kennel as soon as the door is opened, already (too) highly excited, and not wait to be invited out of it, is a significant warning sign to me. Read : intolerable. ~~~~ Regrettably, I do not see in this video a working dog eager to please his owner. And I bet the dog thinks he can do any time whatever he was trained to do. That may well be the 'reason'... I will go as far as affirming that this particular dog should NEVER have been trained to attack. Even a chased criminal would not deserve to be hurt so badly by this animal. ~~~ In addition, unless this dog works HARD daily, it is more likely that his extraordinary drive will trigger some erratic behaviour again. ~~~ If that attack was not instinct, then one would have to consider that this powerful dog has a neurological problem.

Rage Syndrome in dogs is a seizure disorder that leads to unprovoked aggression. Episodes tend to come in threes. Seizure meds may help.💔 Sourced: Wikipedia and Google

[@jeanettelong-i6j]

When hearing of the unprovoked attack on the new owner had me reliving the past....I purchased a Springer Spaniel from the most well known breeder in US years ago for my sister-in law. I showed dogs (different) breed) for over 35 years. At 6 months of age this dog started exhibiting "problems", which I attributed to my sister-in-law's lack of training a dog. One morning my brother came over with both arms bandaged--I asked what happened to you--he said " " attacked me. I asked him what he was doing when it happened, and he said he hugged him. I did some basic training with him and figured if there would be a problem it most likely would show up when putting him in the down position--pressing on his withers. Sure enough, he stiffened and reminded me of the Incredible Hulk. Luckily I had a choke collar on him and knew how to keep a dog off me--even if it meant making the dog a helicopter. I also was a vet tech for 45 years.I started asking Springer people at the shows if they had any problems with their dogs as far as dominance, aggression goes--ALL of them said no. One day a friend of mine who showed cockers said she had a friend who used to show Springers. I talked to her, and she said yes, there was a problem in the breed and it was called rage syndrome. She mentioned a certain dog in the pedigree that they thought was a carrier. By this time the dog was a little over a year, living with me and had almost finished his championship. Even though I showed him I would never have considered breeding him. I finally called this world known, writer of books, breeder about the issue with the dog. The reply I got was--Yes, there are a few dogs that are like this--put him to sleep. Yep, that is the answer I got, and unfortunately that is what had to be done...it was like having a loaded gun lying around waiting to off. Rage is now found in other breeds too. Back when I/we encountered it little was known (1980s). Sorry I got carried away. Thanks

Enjoyed the video, thanks for sharing. But so many questions. You get the dog, form bond, train him and sell (I assume) him. Things are good with new owner/handler for a while and then for whatever reason Mace attacks him. When you went to pick the dog up you used a catch pole---did he not recognize you when he saw you? When you were getting him out of the kennel at your place why did not put him in a sit command, open the door, and then leash him? He was trying to rush the door and push through---not cool---he should come out when you say so. It was like a scene from the animal shelter with all the barking, excitement. Do the other dogs not know what quiet, shut-up, hush mean? And this is just a side note--what is with the hair on his back--can he not be brushed, groomed? Not a hater, just wondering. Thank you.

Most say you can not rehabilitate & refuse to work with challenging “working” dogs. This one is from poor breeder, puppy mill, & has epilepsy. She would rather be a K9. It’s the wrong setting for her (like a senior or a family or apartment) for most any true “working” dog. I had hoped to train as my SD. oops OOPS You’re showing the right way, with respect, to do it. Thanks so much. ⭐️🙌 I know I can’t ever re home my girlie, unless it’s to a K9 experienced person, if I have to replace an ankle, just hoping she’d be prepared to be a good companion for the right person if it’s not me. . (Unlike my 4 previous AKC GSD’s…over 40+ yrs around me as I raised my babies in the 80’s’s). My current GSD has only had treats from my 3 yo granddaughter (my dog is 3 1/2) when she’s in her kennel. Someday I know they’ll be friends .. when rules can be unquestionably followed. Safe, not sorry.. don’t give up. You couldn’t change this behavior by beating it out of them… so many don’t understand this.. clear training & micromanagement.. knowing the consequences… If she lives 11 more yrs I’ll be 80. I love the collar you showed. Glad she’s only 62 lbs of lean. Loves people, my fault she’s the 1st dog I’ve ever been bitten by .. was my fault 3 times, seizure one time - still my fault.

Just curios as I have heard of this before and the connection with the dog has been suspect. Is the Handler mentally ok now? I know he probably want nothing to do with mace now. But you know getting back on the horse or finding a reason why, may make sense of this. I apologize if my curiosity is overstepping.

I know you are professionals but when you have a dog like Mace not knowing what was the trigger, doesn't that carry some worry and fear while you are handling him?

Some dogs like Mace bite their handlers based on an experience they had with their original handler. My favorite dog, a very strong Malinois came to me expecting that I was going to do something to him. We would go on walks and he would start eyeing up my hands. It took more than a year to develop a real bond with him. The first year was a hoot. I laughed when I saw your collar. My dog wore one every time we were out, for a long time.

[@zangzang1268]

New here but let me ask. You did some distraction/control work with the toy. With the bite work, I've worked with trainers that in cases with dogs like Mace, real flamethrowers, kept the bite work toned down with emphasis on control. Work obedience out in the training yard while other dogs were hitting the decoys. Also, when they were allowed to bite they would remain quiescent and just let the dog bite - never shake them up or piss them off. Control wise get them to the point of reliably doing a call-off without a bite. Some dogs we just limit the bite work altogether and work control and socialization as the aggression component is there. Just wondering.

[@elitedefensek-9578]

Please keep everyone posted of Mace. He left and didn't hear anything else about him. This is a special dog, to be honest we need more like him. There's a diminishing of strength in so many of the working breeds such as German Shepherds, Dobermans ,Rottweilers, Malinois, even the Dutchie.

[@User-b2t4j]

I have two Dutch shepherds, came from two different lines and no handler/people/dog aggression. You can say there is handler aggression in any breed.

[@Nil-tz6gy]

They breed some of these dogs to be crazy breeding for bitework - Haz likes them crazy, but I think breeding for that much intensity is like a time bomb waiting to go off

[@jfkst1]

I love Dutch Shepherds. Have one now and probably always will. I definitely notice more dominance and sharpness in their working lines than even Mals and GSD. That said, you are correct that lineage means a lot and Mace is KNPV lines which makes me question how much "Dutch Shepherd" he really even is.

[@joyfulk9services]

Please share as much as you can about this process!

[@mikeutube011]

If you teach a dog to be aggressive(even on command) don’t be shocked when a dog shows aggression, especially one that doesn’t need human intervention or coercion to perform tasks like the Dutch Shepherd. Dogs who don’t are the exception, not the rule.

[@bradtremblay2111]

Have any of your other trainers handled Mace?

[@seanmoore9878]

This dog is not a protection dog.

[@MrOrcslayer]

Not sure the dog is fixable....but you are giving him a second chance.

[@viamia8339]

Can you Show us some Tools how to handle a dog attack.

[@davekenney3693]

Yes it does my shepherd went after my wife the person that he has been with all his life we still are not sure what happened but moving forward I will be the only one handling him your so on point have a great day my friend.

[@victoriafaucher7391]

Wow. Is it a German Shepherd, if I may ask?

[@hiddyboy101]

I think you are the only one that the dog has bonded with after being sold. You will never be able to sell him.

[@JM-cu5ef]

Wow!! Haz.. your the man.. the patience and calmness u had while takin Mace out if the kennel is superb.. your both amazing.. Reminds me of Danger, as you mentioned in your podcast but mace is a little bit mellow maybe compared to danger Enjoy training

[@domazz63]

Dogs are one man owners from pups. That's the whole issue with preliminary dog training. Not all dogs are transferable. You can see it with Mace's original breeder. Keep your eye on the balloon 🎈

[@domazz63]

Let's breed him

[@TheWackler]

When you hear people (mostly breeders) say "I brought this dog in into the world it's my dog til it dies" that's what they mean and that's what you should see from your breeder not just hear!

[@ChuckLundborg]

Dude I screwed up asking about the two dogs , how do I house a protection dog in the home , and retain his prey and mix defensive traits

[@aaronpotter2000]

Genetic trait? Knpv sometimes put other breeds into the mix, could be genetic?

[@flyingpuma9729]

Why would anyone get a dutch shepherd? When you can have a german shepherd. Same qualities in term of guarding and intimidation factor if not better. + better character

[@TDCIYB77]

IMHO Dutchies are the new hype pet dog breed.. And sadly it is really a tragedy.

[@flyingpuma9729]

@@TDCIYB77 Yes, they are the next pitbulls

[@jfkst1]

IME they can be very good all around workers. Less social and more sharp than FCI Mals. More manageable energy levels and impulse control.

[@timothyotoole8224]

things happen is what I say , it was a accident. nice of you to take over the dog .

[@irishseven100]

So sad he is such a magnificent animal..

[@zacharyallen8792]

Dutchies are good dogs I have 8 and they can be bullhead but are good dogs and can be handler sensitive I have a good amount of experience with this breed I had one assigned to me when I was in the marine corps and they are a pleasure to work with haz you will get him where he needs to be if anyone can do it you can brother

[@dannykreckman8303]

I’m waiting for my copy of your book in the mail right now!! Can’t wait!!

[@Kathleen-Wellner]

It's definitely a high-risk dog. And the odds of him doing it again is extremely high! This dog has no respect for humans and is a liability risk.

[@K9inc722]

No working dog respects human and neither it should ...respect is earned through fair training ,its not a given

[@richardspinelli1433]

I have a soft spot for mace..my GSD is a problem child..If I had the space I would really try to buy this dog if that's even possible..Me and mace would do just fine together.

[@melcin]

I was at a PSA trial taking pictures. A Dutchie and his handler were supposed to be next in the ring and something happened with the previous dog and the Dutchie was asked to wait. Once the dog realized he wasn't next in the ring he bit the shit out of his handlers arm. I guess he was going to get his bite one way or another...

[@leastamongyou1111]

Well I agree 💯, my Dutch shepherd is very obedient. Can sit, stay, lay, come, jump, out, whatever, but he nips alot and is VERY AGGRESSIVE.

[@Imme-o7c]

Extremely excited and AGRESIVE. I just hope they don’t become a popular breed as this means. They will overbreed and many will end up in shelters.

[@Imme-o7c]

He is really big for the breed.

[@exmormonsongbook]

We are using a dominant dog collar made of paracord that Heff gave us. Is the steel cable one better? Did you make it yourself?

[@keithschaeffer]

beautiful dog

[@JetPackDino]

I believe Mace has a new nome now, so congratulations to all. Any updates?

[@uncle_creepy2743]

had my dutchie stop going after a squirrel he tried to nip me. i threw him down, flipped him. he good now.

[@brigittebengtson8514]

You obviously know what you're doing, but you are very brave as well!

[@selfmadelen]

Looking forward to see more updates!

[@VonGontaHaus]

I would take him to a vet and get his serotonin level checked. He could have a brain chemistry imbalance. Serotonin and Dopamine imbalance could be a real issue. Hypothyroidism is also a medical condition. I would not ignore a possible as a medical condition. A common endocrine disease where the body produces an abnormally low amount of thyroid hormones. An autoimmune destruction of the thyroid gland, which affects more than 50 dog breeds and crosses. It's possible. I would get blood work on him to rule out a medical cause. Low thyroid levels can cause aggression. I really feel bad for this handler. No matter how you slice it, Mace is not a stable dog.
