My 9-year-old dog is lethargic and slow. Could it be arthritis?

Updated on September 23rd, 2025

Pet's info: Dog | Mixed Breed Medium (23 - 60lb) | Male | unneutered | 10 years and 6 months old | 40 lbs

I am concerned about my 9yr old dog's behavior over the past 2wks. He is lethargic, walking slowly, seems to have no energy. He doesn't jump or run at all. He is not himself to a noticeable extent, but I hesitate to take him to a vet b/c he is eating and drinking normally, using the bathroom, and doesn't have a fever. I am looking for some advice.

I can certainly understand being concerned about Bear! It could be that he is painful and has arthritis. Arthritis is common in older dogs. I would take Bear into the vet for an exam. The vet can diagnose if he is suffering from arthritis, and can give him some pain meds for it. Rimadyl (an NSAID) is a good drug to give to help with the symptoms of arthritis. I also recommend giving him glucosamine or chondroitin sulfate supplements. They provide the necessary nutrients for cartilage repair and function. Use of them helps relieve some of the symptoms of arthritis, and you can use it in conjuction with Rimadyl to help maximize relief from his symptoms.
