I took my rescued pup for a well dog check up today. He is my pride and joy. While in line to pay, this cute little strange looking dog was behind me. He is a doxi, wirehair terrier, ?? mix with funny fur and a cute face. My dog loved him, and they started playing together. They both weigh 25 pounds and tumbled across the floor. I asked the woman who had him about him and she said he's a foster, 10 months old found in Kentucky and brought north to a foster group. Now my husband wants him. He's very sweet ,she said, laid back, likes people and cats and is house and crate trained. I have never had two dogs at one time..cats yes. Five of them presently. My dog is a treasure and I would hate to have anything spoil that. He has never had an accident in the house, is super smart and a dear dog. He's my best friend. I'm worried another dog may change that. People w/ multiple dogs, are your dogs as affectionate and nice as they were before you introduced a new pet?
