Why is my 14-year-old Labrador lethargic, panting, and eating slowly?

Updated On September 23rd, 2025

Pet's info: Dog | Labrador Retriever | Male | unneutered

My dog is 14 years old, a chocolate Labrador and the past day or so he's gotten really lethargic, staying in certain places and not really moving a lot and today he's started eating slowly which is very unlike him (but he is actually still eating) and he's panting a lot and breathing heavily. What could be happening?? I'm worried

I'm sorry Odie isn't doing well! He could be in pain, causing him to be very lethargic and not moving a lot. Pain would also cause him to pant and eat less. His pain could be caused by arthritis, which is common in senior dogs, or hip dysplasia. There could also be other medical illnesses causing his symptoms, such as heart disease or cancer. I would have him seen by a vet today for a physical exam, geriatric blood test, urinalysis, and possibly chest and hip x-rays. These tests will determine what is causing his symptoms so he can be treated as needed.

    Hi here and thanks for using Petco Pet Education Center, formerly Petcoach! Sorry Odie isn't feeling well. It sounds like you pay very close attention to your pet's behaviors to notice small differences-this is wonderful and actually helps us a lot. With his age, I am at increased concern for organ health. If he hasn't had any bloodwork performed recently, it may be time to take him in for a checkup. As seniors, it is very important we keep an eye on the organ functions (especially liver and kidneys) in our pets. Panting and breathing heavily can be a sign of discomfort or pain as well. If your dog seems painful on his abdomen, or is bloated in any way it is likely your doctor will also recommend x rays to make sure everything looks normal from the inside (no tumors, etc) I would recommend having him seen as soon as you can, especially if these conditions persist. Tell your vet what's going on so they know how long and exactly what to expect, and normally we will work with you as best we can if one is suddenly very ill. I hope he feels better soon. My best to you both.
