Gimpy

Oliver has been on and off limping for a couple of weeks. At first I freaked out and would check him over to make sure there was no obvious reason for the limping- then he would run off and everything would be back to normal. Then he would start up again- I began to wonder if is something he turns on for attention? I think I'm going to call the vet tomorrow, I will feel terrible ignoring this if it turns out that there is a physical cause, if he is just doing it for attention? I feel bad that my dog feels like he has to gimp around and pretend to be lame in order to get enough attention from me. But if I start to think about there being a physical cause it makes me nervous, it starts my mind down a path that I would prefer not to travel. Honestly I almost hope it is for attention, that is a problem I can fix. If it's his health... he's five years old, and while that's not super old in dog years, he's not a puppy anymore and the thought of him having something wrong with him really bothers me. For now I'll just carry my gimpy little guy to bed and call the vet tomorrow and hope for the best.
