Mini Schnauzer 7 years old tired and aloof
My schnauzer is acting really tired and aloof lately. I am really worried because I had a Schnauzer before that died at 7 from diabetes. He does not have excessive thirst, or anything like that. I wonder if he is depressed because I do not see a friend that was close to him anymore? I don"t know what to do, and can't afford the vet. Any suggestions?
