Pano in Dogs - Everything You Need to Know
Getting a new puppy is an exciting time. Along with housebreaking and training, there are some issues that are exclusive to young dogs — one of which is a condition called panosteitis. Panosteitis, or "pano" for short, affects puppies aged roughly two years or younger. While it's fairly common, it can be very uncomfortable for your pup. The good news is there are plenty of ways to help a dog with pano feel more comfortable while it runs its course.
What is Pano?
Panosteitis is a condition that causes lameness and/or limping in young dogs. It's sometimes called "growing pains," since it typically affects dogs during their first two years of life. Symptoms usually arise between 5–14 months of age, though there have been cases in dogs as young as two months and as old as 18 months. After a dog reaches two years of age, the effects of pano typically disappear — quite randomly.
Pano can more simply be described as "bone inflammation," because that's essentially what it is: inflammation on the outer surface of the long bones of young dogs. This causes discomfort, which leads to limping. In most cases the front legs are affected, though it can affect the back legs too. The root causes are unknown — some research has drawn links to diets rich in protein and calcium, while other research points to a wide range of possibilities, from infections to autoimmune factors to rapid growth or stress. One of the strongest observed links is genetics, and more specifically a dog's breed.
Breeds Most Affected by Pano
Some breeds appear more susceptible to pano — typically large and giant breeds such as:
- German Shepherds
- Great Danes
- Dobermans
- Golden Retrievers
- Labradors
- Basset Hounds
- Rottweilers
This doesn't mean smaller dogs are immune. Monitor your pup's behavior and movement so you can identify a possible pano episode as early as possible.
Signs and Symptoms of Pano
The most common sign of pano is a lameness or limp that appears out of nowhere. It can last anywhere from a few days to a few weeks, and discomfort ranges from mild to severe enough that your dog won't want to put weight on the leg at all. The affected leg may become so sensitive that even touching it causes discomfort. Once an episode subsides, it usually returns about thirty days later — in the same leg or a different one. Other symptoms can accompany pano, such as fever, loss of appetite, or a high white blood cell count. Because these overlap with several other illnesses, it's important to visit your veterinarian to confirm the correct diagnosis. Your vet will typically take x-rays (and sometimes blood samples) to rule out a more serious issue.
Hypertrophic Osteodystrophy (HOD)
Another bone condition that affects young, large-breed dogs is hypertrophic osteodystrophy, commonly called HOD. Like pano, HOD causes pain in the legs of young pups, but it affects multiple legs at once rather than a single leg, and it tends to be more painful. No specific breeds seem more susceptible, though male dogs are affected more often than females. HOD is diagnosed the same way as pano — through x-rays and blood tests — and is a more serious concern, since it has the potential to permanently damage the growth plates if the swelling doesn't subside.
Osteochondritis Dissecans (OCD)
A third bone condition that affects young dogs is osteochondritis dissecans, or OCD (very different from the kind of OCD you hear about in humans). OCD specifically affects the cartilage in a young dog's joints. Normally cartilage attaches to the bone, but with OCD the cartilage separates and begins to dry out; eventually pieces chip off and float around the joint, causing discomfort. Symptoms usually appear between four and ten months of age. As with pano and HOD, lameness or limping occurs, but unlike the others, OCD can also be found in a dog's shoulders. Depending on severity, surgery may be required to remove the chipped pieces.
Treatment for Dogs with Pano
With many illnesses we take preventative measures, but with pano there isn't really anything you can do to keep your pup from developing it, and there's no cure that prevents symptoms from returning. Pano eventually goes away on its own, and there isn't a way to speed that up — but there are several ways to help keep your pet as comfortable as possible in the meantime. Work with your veterinarian on a plan.
One of the more obvious ways to make a dog with pano more comfortable is to restrict their activity — limiting running and jumping while their joints are sore. You should also make sure your dog isn't overweight: an overweight dog puts more stress on the joints, which can make this uncomfortable condition feel worse. Your vet can also discuss medication options with you if appropriate.
A Daily Joint-Support Option
Alongside rest, weight management, and your veterinarian's guidance, a daily joint supplement can be part of supporting your dog's overall joint health as they grow. FlexPet is an all-natural daily supplement for dogs, formulated to nourish the joints, support healthy cartilage, support the joint's natural lubricating fluid, and support a healthy inflammatory response. FlexPet is a supplement, not a medication — it isn't intended to diagnose, treat, cure, or prevent pano or any other disease, and it isn't a substitute for veterinary care. FlexPet contains:
- CM8® (Cetyl Myristoleate) — a naturally occurring fatty acid studied for its role in supporting joint comfort and a healthy inflammatory response.
- Glucosamine Sulfate Potassium — a naturally occurring compound that plays a key role in cartilage construction and the incorporation of sulfur into cartilage.
- MSM (Methylsulfonylmethane) — a naturally occurring sulfur compound; sulfur is needed by the body to form connective tissue.
- Hydrolyzed Collagen Type II — a building block of the cartilage that cushions the joints, providing tissue-oriented nutritional support.
- Bromelain — a plant enzyme found in pineapple that supports a healthy inflammatory response and helps with digestion of the other ingredients.
- Enzyme Blend — helps the body absorb larger molecules like CM8® so your pet gets the most from each serving.
Final Thoughts
Knowing your dog will eventually outgrow their pano symptoms doesn't make it any easier to watch them uncomfortable. With the right combination of diet, rest, veterinary care, and a daily joint supplement like FlexPet, you can help support your pup until they're back to being the playful dog you fell in love with.
