Ask the Vet - What age to start your horse on joint supplements

[@HeatherDMorris]

My 3.5 yr old is lunged 2 times a week and lightly rode and I may add a joint supplement

I'm researching this topic as I just found out my 6 month old weanling has a slab fracture of her hock from a kick she received at 6 weeks old. She's going in for surgery in a few weeks. I'd always planned on starting her on joint supplements at 3 years old, but now with the increased risk of arthritis, is 6 months old too early? (Concern being any odd effects in growth plates etc. )
