A puppy who was attacked has a 90% chances of growing into being leash aggressive or exhibit fighting tendencies. Their dog probably exhibits these behaviors because @ one point s/he suffered an attack. Its not the easiest behavior to overcome & becomes instinctual when a dog feels threatened or need to protect. One day your sister may be involved in a reverse situation. Perhaps someday even bite a neighbors dog ?[/QUOTE]
I have re-read this para a few times. I have a leash aggressive dog. He became that way after being attacked three times while he was leashed. Two of those attacks were very close together and nearly on our doorstep. Poor guy! I train, teach, and compete. I understand.
Are you saying because the attacking dog may be dog aggressive, and now her pup has a 90% chance of being aggressive, to give it a pass?
Give it a pass because now my sister’s dog will become that offending dog? Like pay it forward? 
As her trainer said after hearing the story and seeing the wounds, “that dog needs to be muzzled.” Even simpler: a d@mn LEASH!
After reading the comments this thread received shortly after I posted it yesterday, I decided to not repeat the AC convo with my sister, since it seems the majority think I’m overreacting.
Maybe I am. I’ll take my COTH lashes and learn. I am definitely the dog owner equivalent of a COTH AA hunter or Advanced eventer, not the single string of barbwire fence, a Parellite, and a bicycle chain bit :lol:. I feel like, overall, I’m hearing lighten up.
Marshfield, thank you for the info! I shared with my sister yesterday.
