I was between these 3 dogs before I adopted my Shih Tzu. She is 15 pounds very strong, vigorous, playful and athletic. But she is still tiny, I want to see if any of these 3 breeds that I liked would be compatible with her. Not really interested in any other dog but these three. Thanks for the help.
A Rough Collie.
They are extremely gentle with other animals.
They are wonderful dogs and easy to train.
My Rough Collie is a wonderful "sister" to my Pomeranian. She lays on her back so the Pom can stand on top of her and chew on her throat when they play.
I can not say enough good things about a Rough Collie.
English Bulldogs are the most unhealthy breed of dog, with many medical issues. I would never suggest this breed to anyone.
Boxers have EXTREMELY high energy, I think they would just be too much dog for the Shih Tzu.
