Dr, thanks for the answer.
the dog is mixed mutt looks like he has some corgi or something short and stocky in him. he is about 6 years old and was on the verge of death when we found him as a puppy. he has had a decent life and he is a great dog with the kids (almost 6 and 4) but some days he has a really hard time like he has arthritis and whines as he gets up sometimes, but otoher days he does awesome which is why I think arthritis since I get that. but I also think he gets some muscle spasms. Is there something you would reccomed, we had gotten some over the counter stuff from the petstore that seemed to work, but we are out so I was just looking to see what we could do in times like this with what we have, asprin, motrin and the likes.
