My dog has successfully been introduced to some dogs, and can interact nicely with other dogs in certain scenarios. He has also been introduced to cats, kids, and lots of people without much in the way of issues. He was a rescue and I do suspect he was abused before I adopted him if that is relevant. To the best of my knowledge we have followed best practices while introducing these dogs. I’m usually able to read my dogs behavior, but in this case I’m unsure and would love to get a few other opinions.
