We have had Deuce for a few months. Unfortunately we have to find a new home for him since we are not home a lot and Deuce spends a lot of time in his cage, therefore, does not get the exercise and attention that he needs and wants. Deuce is very good with our other dog but not sure about cats. The people we got him from a few months ago said he is approximately 3 to 5 years old. Deuce is a very happy guy and loves to play but is possessive of his toys. We do not have kids so not sure how he is with them but the people we got him from did have kids.only serious inquiries please!
