Is My Dog Just Getting Old? What Actually Helps a Stiff Older Dog

By Doc Farnum, DVM

He used to beat you to the door. Now you hear him first: a push with the front legs and then the back end coming along a beat late. On cold mornings he is stiff for the first few steps. He looks at the couch before he jumps, like he is measuring it. And the walk keeps getting shorter, because he is the one turning for home.

The thought nearly every owner has is that he is just getting old. It sounds kind, and it sounds like there is nothing to do.

A lot of you already suspect it is more than age, which is likely why you are reading this. I am a veterinarian, so I will give you the most important part first.

When an older dog is stiff, it usually means something hurts. Most often that is arthritis, and arthritis pain is one of the most manageable problems a senior dog has. Waiting it out is the mistake, because a sore joint left alone tends to get worse. Book a regular appointment with your veterinarian this month and tell them exactly what you have been seeing.

Call your vet today instead if he suddenly will not put weight on a leg, cannot get up, cries out when he moves, or his back legs are wobbly or dragging. Those are not the slow wear of arthritis.

Is my dog just getting old, or is it arthritis?

Some of what you are seeing really is age, like the gray around his muzzle and the longer naps. Getting up slowly, or stopping to size up a jump, is different. That usually means a joint hurts.

The most common cause is osteoarthritis, which is what vets mean by arthritis in a dog. The cartilage that cushions the ends of the bones inside a joint wears thin, the joint gets inflamed, and the body lays down extra bone around the edges. The joint moves less freely, and it hurts.

Owners miss it because dogs do not complain the way we do. A dog with a sore hip rarely whimpers. He adjusts, and because the change comes on over months, it looks exactly like getting old. It hides in young dogs too: a 2024 X-ray study of dogs 8 months to 4 years old found arthritis changes in about 4 in 10 and concluded the pain is underdiagnosed.

Waiting costs him more than time. A dog who hurts moves less, loses muscle over his hips and usually gains weight, and both of those put more load on the sore joint. That loop can run for a year or two before anyone calls it anything but age, and muscle an older dog loses is slow to come back.

The signs of joint pain owners miss

Put your eyes on him getting up from a nap on a cold morning. That is when arthritis shows most plainly. Watch for:

• Stiff after lying down, then better after a few minutes. Stiffness after rest that loosens with movement is the classic arthritis pattern, and warming out of it does not mean it does not hurt.
• Lying down in stages, or circling a long time before he settles.
• A pause before the couch, the bed, the stairs or the truck. The hesitation shows up long before he quits jumping.
• The shorter walk. Lagging behind or turning for home early looks like lost interest. Often it is not.
• Sitting crooked, with one back leg kicked out to the side instead of tucked under him.
• A thinner back end. He shifts his weight forward and the muscle over his hips shrinks.
• Licking one joint, or turning grumpy about being touched on the hips or back.
• Restless at night, or having trouble squatting in the yard.

Before the appointment, take a video. Many dogs move better at the clinic than at home, because nerves and excitement cover the stiffness for a few minutes. Twenty seconds of him getting up in the morning will show your vet more than you can describe.

When it is more than arthritis

Not every stiff dog has arthritis, and some of the other causes will not wait. A dog who suddenly refuses to put weight on a leg often has a torn cruciate ligament, the dog version of a torn ACL. Wobbly or knuckling back legs, or toenails that scrape the ground, point to the spine or nerves. A limp that keeps getting worse, or a firm swelling on a leg bone in a large breed, needs a vet soon. Call rather than book for any of these.

What actually helps a stiff dog

Arthritis cannot be reversed, but the pain and stiffness usually can be managed well. A lot of owners are surprised how much of what they took for old age turns out to be pain.

1. Get him lean. This is the big one.

If he is carrying extra weight, taking it off is the best-supported thing you can do for his joints at home, and it does not require buying anything.

In a lifetime study Purina researchers ran on 48 Labrador Retrievers, the dogs were paired, and one dog in each pair ate 25 percent less than its partner from 8 weeks old on. The leaner dogs lived longer, and their chronic health problems generally showed up later. Hip arthritis on X-ray first appeared at a median age of 6 years in the dogs allowed to eat freely. In the lean dogs, it was 12.

It still works if he is already heavy and already sore. In a 2010 study of 14 overweight dogs with arthritis, lameness improved measurably once they had lost about 6 percent of their body weight, with weight loss as the only change. On a 70-pound dog, that is about 4 pounds.

To check him, lay your hands flat on his sides. You should feel his ribs easily without pressing, and from above he should have a waist behind them. If you have to push to find ribs, he is carrying extra.

If he is heavy, that is not a verdict on you. Many dogs slow down because they hurt, and gain because they slowed down. Ask your vet for his ideal weight and a daily calorie number (treats count), and take the weight off slowly while the pain gets handled, because a dog who hurts will not move enough to help.

2. Let your veterinarian treat the pain

This is usually where a stiff dog finds relief fastest, and your vet has more tools than most owners realize:

• Anti-inflammatory pain medications made for dogs (NSAIDs), such as carprofen or meloxicam, the backbone of the plan for many arthritic dogs. Expect bloodwork before and during, because in some dogs they affect the liver or kidneys.
• Librela, a monthly injection approved by the FDA in 2023 that blocks a pain-signaling protein. The FDA has since published reports of side effects, so ask your vet about them.
• Adequan, an injection given as a series, approved for the signs of arthritis in dogs.
• Added pain medications such as gabapentin or amantadine when one drug is not enough, and rehab such as veterinary physical therapy or underwater treadmill work.
• Prescription joint diets built around high levels of fish oil.

Needing medicine for a sore joint is not a failure, his or yours.

One hard rule: do not reach into your own medicine cabinet. Ibuprofen and naproxen can cause stomach ulcers and kidney damage in dogs at doses that seem small to us, and acetaminophen is not safe to guess at. Do not give aspirin without your vet, and never alongside a prescription anti-inflammatory.

3. Keep him moving, and make the house easier

Rest is right for a fresh injury, but arthritic joints do better with regular, gentle use. Two moderate leash walks a day beat a quiet week followed by a long Saturday hike. At home, rugs on slick floors and a ramp or pet steps for the truck and the couch save a sore dog a lot of strain.

Where joint supplements fit

A joint supplement is the daily layer under everything above, not a replacement for any of it. Of the ingredients studied in dogs, omega-3 fatty acids from fish oil have the most research behind them, which is why prescription joint diets are built around them.

No supplement takes the place of getting him lean and a pain plan from your vet. What a good one adds is joint nutrition in the bowl every day, which is the part of his care you control.

Where PawMega fits, honestly

We make a daily superfood supplement for dogs called PawMega. It is not a pain medication and it does not treat arthritis. It is nutritional support that goes on his regular food once a day, and it supports healthy joints and mobility as well as skin, coat and gut health.

What is in it:

• Salmon oil, for omega fatty acids.
• Flaxseed, for more omegas, for its lignans, and for digestive health.
• Avian (bird-sourced) type II collagen.
• Glucosamine, sourced from shellfish, which matters if your dog has a shellfish allergy.
• Curcumin from turmeric, and resveratrol.

Separate from the joint ingredients, PawMega also contains PreVent Refined Functional Carbohydrates (PRFC), an immune modulator covered by U.S. Patent 11,844,810.

PawMega is for the owner who wants to do something every day at the bowl, beside the vet’s plan and never instead of it: one daily serving of joint, skin, coat and gut nutrition, from a company a veterinarian started in 2007.

Jovie is my daughter’s dog, a big Saint Bernard mix who, as the family puts it, is “not getting any younger.” She had trouble with stairs and jumping, and she is much more comfortable now.

Every dog is different, and a story is not a diagnosis. But it would have been easy to put it down to age.

The serving is set by his weight, and it has 34 calories per tablespoon, so count it in his daily total. A bag is $42.87, or $38.58 on subscribe and save, and you can try it with no risk for 60 days. If you do not see results, return it, even an empty bag, and we will give you a 100% refund. Bring the bag to your next vet visit, too. A good vet wants to know everything that goes in the bowl.

If he itches as well as aches, we wrote a separate piece on why dogs itch and what actually helps.

Keep score at home

Memory is a poor judge of slow change. Take the same morning video once a month, and note how far he walks before he turns for home. That tells you and your vet whether the plan is working.

He has spent his whole life meeting you at the door. If he is slower getting there because a hip hurts, that is something you can do something about.

Questions about whether PawMega fits your dog? Reach out. We are glad to talk it through, no sales pitch.

Frequently asked questions about stiff older dogs

Is my dog just getting old, or is it arthritis?
The gray muzzle and extra naps come with age. Stiffness after he has been lying down, or a pause before he jumps, usually means a joint hurts, most often from arthritis. Your veterinarian can tell you which.

Can I give my dog ibuprofen or aspirin for joint pain?
Not on your own. Ibuprofen and naproxen can cause stomach ulcers and kidney damage in dogs. Give aspirin only on your vet’s advice, and never with a prescription anti-inflammatory. Your vet has medications made and dosed for dogs.

Is PawMega a replacement for my vet, or for a medication like Rimadyl or Librela?
No. PawMega is nutritional support, not a medication. Keep giving any prescription exactly as your vet directs, and tell your vet you are adding PawMega.

When should I take my stiff dog to the vet?
Book a regular appointment this month instead of waiting to see if it passes. Call today if he suddenly will not bear weight on a leg, cannot get up, cries out when he moves, or his back legs are wobbly or dragging.
