I used to wash my dog like you did, I have 2 Rottweiler and one just died 2 days ago which is the big brother, because of bone cancer (Osteosarcoma), I felt so empty right now... as if my whole world collapse, my family are having hard time too, the saddest part is his brother keep running around my house everyday to search for his brother even though he will never come back anymore... both of them are 6 years old, I just hope that the little brother can live longer...
