More: We rescued Tank from being taken to our local animal shelter when we saw him at a relative's home where he had been thrown out. They were going to take him to the shelter and we said NO we will take him! He is the sweetest dog, loves water more than any dog we have ever owned and is so smart. We had a DNA test done on him and he is a 75% mixture of Labrador Retriever, Golden Retriever and Chesapeake Bay Retriever with a small percentage of Beagle, American Staffordshire Terrier, Bulldog and Basset Hound.
