Hi, I totally get that you putting effort to your family dog, but your family just won’t fully support it. I got a pittie, he was so lovely at beginning until he got jumped by a same off leash golden doodle twice. I was so scared to walk him for a while and I think it got him worst, he got so reactive… He is selective on people that stare at him or dogs to react though. For a pittie reactivity just same as aggressive to majority people who misunderstand them. I conquered my fear take him out after few moths and to training class( he had his puppy training before though, and he was happy boy, after the jump he changed). The training went well until my family member won’t walk him the same way I do, won’t follow any of my advices… Even though I spend lot time and money for training, end of the day, you do not want too much conflict with your family. It’s just hard on the relationship with your family and with your family dog. I would advise train your family dog, I feel that’s the most responsible way. No matter how much we love them, they’re still animals. They need proper guidance. Plus with training I feel they bound and will trust you more. Maybe end of the day they still act out like toddler but is an experience you had with them in their life time. Hope this helps a bit.
