Sweet yet scared dog. Was an owner surrender, owner didn't want to feed him and the dog started getting into garbage cans, so owner brought him to us and said he didn't want to have to shoot him for getting into garbage. Great guy. (insert eye-roll) Aston is a very sweet, submissive and affectionate dog. Heartworm positive, but we have started him on treatment. He needs a home where he will not ever have to want again and will not have to worry about being abused.
