So I have a Cairn terrier (like Toto from OZ), and he is basically a cat. He really just likes to sleep all day and eat. I haven't been able to get him interested in any toys or balls. ON occasion I can get him riled up to play for about 4 minutes and then he is back to sad puppy eyes of, "just pet me". We have had him for two years and he is about 4 years old now. I try to take him for walks, but all he does is mark everything every 4 feet or so. What should be a normal 20-30 minute walk turns into an hour plus with him. So, any suggestions on getting him interested in playing?
