I have to take Zeke to the vet on Tuesday. (I worked all day today and tomorrow. The office is closed by the time I'm off which is why I have to wait til Tues) He's been limping a little bit off and on, but today it seems to be an all day thing. I feel like he must be pretty sore, is there something I can give him? I have a feeling this is all due to his old age, but I hope it goes away soon It's really hard watching them get older...
