Cheri,

More questions. How old is the dog, and what type is it?
My older Lab (9 y.o.) is on Glucosamine and Chondroitin Sulfate for her arthritis. It helps most of the time. A change in weather and she will still limp a bit. Then I will give her a coated asperin. (Tylenol (acetaminophen) is not good for dogs.)
We have had to say goodbye to a number of dogs, most because they had cancer. It was always very hard to do.
