Rocket,
All of our paws are up for Chances recovery emotionally and physically. Just a thought, I would immediately acclimate him to friendly dogs (as in a controlled dog park on a leash) as he is still a pup and a NEGATIVE experience will imprint on his brain. We have a Rottie who we rescued as her FIFTH and FINAL home and do alot of large breed rescue. She was dog aggressive but with our Newfs and being exposed to other dogs it calmed her down. She was 3 and we managed to barely nip the problem in the bud with alot of slow, limited exposure.Chanc e being a Pit, he NEEDS to have a CHANCE to show he can be around other dogs and not become too defensive or overly aggressive, or overly defensive with your kids! Poor Chance, my Newfs said they would come smack that GSD down to the ground for him! They paw things down they are so huge. We won't say what the Rottie said she'd do.....She is not aggressive anymore!
Take care Chance
4 legged hugs and 2,
Donna and Crew
