The dog that responds best to you while at the shelter is usually the best choice. Then again, often the shy one in the back is the one who needs you the most.
It’s up to you. Every dog is a good dog, some just need more love than others.
There are no bad dogs. Only bad owners.
I have had several breeds that have thrived because we treat them like a part of our family, but train them well as puppies as to what is acceptable of them. Once they know their boundries it all goes well.
My next dog will be a Chihuahua. Going to name him Cujo.
