So we have a Black Lab/Golden Retriever mix named Bear, he is 4 1/2 years old. He's always very active and happy and wants to play but over the last few months he keeps getting hurt or he limps and he's been on Rimadyl and Gabapentin. The first time he was acting "lame" as the vet put it was a few months ago. He was limping and in pain, the vet did his examination said its not a break, gave him Rimadyl. Took it a few days, was better. Then a few weeks later he had his head low and almost looked like he felt bad about something but still wanted to play. We took him to the vet, they manipulated his neck and said they thought it was a pinched nerve. Prescribed Gabapentin and after a week or so he seemed better. Then he started limping again maybe a few weeks later and so we gave him some of the Gabapentin but it didn't work. Took him back to the vet and this vet said she thought he just pulled something so prescribed Rimadyl. He's been on that for a little over a week. The last 3 days he's seemed fine. Today, we come home from work and he's got his head down again, looks stiff and doesn't want to look left, definitely looks like someone whose neck is very stiff. He did lay around all day today, no horsing around as far as I know but I don't know what to do. Gave him a Rimadyl as he was supposed to get one but I don't know why he keeps winding up in pain. He's a very active dog and never refuses to play or eat. His gums are healthy pink, no fever, just stiffness. I feel like he's too young to have arthritis. I asked the vet the first time about testing him for Lyme disease because his Mother is very stiff as well and only about a year and a half older than him but they didn't want to test her either. Neither of his 2 brothers has these issues. The vet talked me out of the Lyme test saying that he didn't feel any swelling in the joints and he could have been exposed to it but not actually have it so the test could come back false positive? Then how do they diagnose it? I just feel bad everytime we take him to the vet and he starts feeling better it's something else and he's in pain again. Anyone have any ideas or maybe a direction I should take? Thanks so much.
