More: The tallest dog is Tank and he was our first and came from a breeder. Jet the second biggest dog was adopted so Tank would have a friend. Then Ash came along and was a rescue who then completed our already large family. (7 kids and now 3 dogs) Together they have learned it does not matter where you came from it’s all about how your raised and loved. If only humans could be as accepting as dogs our world would be so much better! Equality at its finest!
