You know your dog is getting old when?

When he has been laying in his bed all afternoon and he refuses to get up to go out. He did eventually get up, but it was like, a huge effort for him. My poor boy is getting so old! He’s 12 now. I think he may be getting a little bit of arthritis in his joints, poor boy. I gave him a treat when he came back in. I don’t think he actually did anything when he went outside, except stand looking at me and he was probably saying in his head, mom, its cold out here, let me back in! He’s such a cutie, love him to pieces! I wish he didn’t have to get old.
