So I was asked how I can have two bullies in my pack, especially with the small dogs. I felt I needed to share a picture with everyone.
This is our bully Shelly showing her true nature of keeping our Chihuahua warm. Bull breeds can live peacefully with other dogs, Shelly and Axel are proof of this. They both had come to us with a bad past and yet they live happily with our entire pack, our resident cat included.
If you take the leadership role in your house and practice simple boundaries your bully can become calm and accepting of all animals.
