Ask a Dog Vet and Get Answers to Your Dog Veterinary Questions
Hello. Thanks for the question.
Is he acting painful?
Any vomiting/ diarrhea?
Any trouble jumping up onto couched/ furniture or doing stairs?
The signs are kind of vague. My guess is that he hurts somewhere. It can be difficult to diagnose where, though. We see this a lot at the ER- acting weird, not as energetic, off their food. One of the more common causes, is back pain from a disc herniation. Those dogs are also reluctant to jump up or do stairs. They may still do it, but it's slower and painful. They may also yelp when they're picked up.
With these mild signs, I would probably just take it easy with him at home for a few days. If the signs seem to worsen, then get to a vet. As long as they slowly improve day to day, it should be something that works itself out at home.
If you want to try an over the counter pain med, Aspirin is the safest. The dose in dogs is 5 mg per lb body weight every 12-24 hours, as needed.
I hope this helps, let me know if you have any other questions.
