Dogs do not whimper when they hurt. They adapt. That is the cruelest part of aging in a species that cannot tell you what is wrong. Most senior dogs I see for “acting weird” are in chronic pain, and the owner had no idea.
Here are the signs I look for in my own senior patients.
Behavioral changes owners often miss
- Slower to get up in the morning
- Reluctance to jump on the couch, or missing when they try
- Choosing to skip stairs
- Sleeping more, but restlessly
- Grouchier with other pets or kids
- Less interested in walks, or turning around early
- Panting when it is not hot
- Lip-licking or drooling when at rest
Any of these on their own could be aging. Three or more, or a sudden change in any of them, means pain until proven otherwise.
Physical signs
- Muscle wasting on the back legs or over the hips
- Stiff, straight-legged gait after resting
- Reluctance to be touched over the hips or spine
- Difficulty squatting to poop
- Slipping on floors they used to handle
- Nails wearing unevenly
What causes chronic pain in senior dogs
The three big ones:
- Osteoarthritis. By age 8, more than half of dogs have arthritis somewhere. By 12, closer to 90 percent.
- Dental disease. Rotten teeth hurt every time your dog eats or drinks. Many older dogs stop eating dry food not because they are picky, but because it hurts.
- Back pain. Especially in dachshunds, corgis, and other long-backed breeds. Also common in overweight dogs.
What actually helps
The good news: chronic pain in dogs is very treatable. The bad news: your dog will not tell you it is working. You have to watch.
- NSAIDs specific to dogs (never human ibuprofen or Tylenol, which are toxic)
- Adequan injections (a joint support drug we use monthly)
- Weight loss if applicable (this alone can eliminate a limp)
- Acupuncture (I do this in-house, works well for many dogs)
- Joint supplements with real evidence (glucosamine, omega-3s, Dasuquin)
- Physical therapy and controlled exercise
- Dental care to address oral pain
The test
Try this. Ask your vet for a two-week trial of an NSAID. If your dog is suddenly running to the door, jumping on the couch, or bringing you a toy again, they were in pain. That is your answer.
Old age is not a disease. Pain is.
