Of COURSE one of the dogs was a Pit Bull.
Pit bull/boxer mix. Both were large and grossly unsocialized, I’ll wager. Utterly untrainable, which was why they ended up in a rescue situation. People that give away or sell pups at 5-6 weeks are setting the dogs up for this kind of crap. Doesn’t matter with ankle-biters, so much, but a 60 pound dog can be formidable, and multiple dogs can be a nightmare.
In before the “it’s the owners, not the dog” people.
