The best supplement for a dog after FHO surgery

The best supplement for a dog after FHO surgery is a broad joint supplement that supports the joints doing extra work during recovery, along with the tissues around the new false joint. Look for glucosamine, chondroitin, MSM, green-lipped mussel, hyaluronic acid and omega-3s. It will not heal the hip. Rehab, muscle and a lean body weight do that work, and the supplement sits alongside them once your vet is happy.

FHO, short for femoral head ostectomy, removes the ball of the hip joint. The body then forms a fibrous false joint in its place, held in position by the surrounding muscles. That makes recovery after FHO different from most orthopaedic surgery: the result depends heavily on how well your dog rebuilds muscle and how much they use the leg.

Choosing a Joint Supplement for FHO Recovery

After FHO, your dog's other hip, knees, back and front legs have often been compensating for months, and they keep working hard while the operated leg gets stronger. If your vet agrees a joint supplement is suitable, here is how the UK's best-known options compare on the key joint actives.

MedPaw is our own product, so every entry below comes from each brand's published ingredient list.

MedPaw Hip & Joint Chews Max is the only product here that lists all six key joint actives, with omega-3 from green-lipped mussel and flax seed plus vitamins C and E and zinc. For a dog recovering from FHO, that means one daily product covers the joints carrying extra load, without stacking several supplements on top of post-operative medication.

It is a soft chew, which helps when appetite is fussy after surgery, and it comes with a 60-day money-back guarantee. As with any supplement after an operation, check with your vet before you start.

What Is FHO Surgery?

In a femoral head ostectomy, the surgeon removes the head and neck of the femur, the ball part of the ball-and-socket hip joint. Without bone rubbing on bone, the painful contact goes. Over the following weeks, scar tissue forms between the femur and the hip socket and creates a false joint, supported by the muscles around it.

Vets typically recommend FHO for hip fractures that cannot be repaired, hip dislocations, severe hip dysplasia or end-stage hip arthritis, and Legg-Calve-Perthes disease, a condition of small breeds where the femoral head loses its blood supply. Our guide to dog joint surgery, including FHO and hip replacement explains how vets choose between the options.

FHO tends to work best in smaller, lighter dogs. VCA's veterinary guidance gives about 45lb (roughly 20kg) as the typical upper weight, although larger dogs are sometimes treated this way. VCA also notes that active dogs often do better than less active ones, because muscle mass helps stabilise the false joint.

The FHO Recovery Timeline

Every dog and every surgeon is different, so always follow your own vet's plan. As a guide, published post-operative advice from veterinary surgeons follows a similar pattern.

Southwest Veterinary Surgery notes that the time it takes dogs to start using the leg varies a lot, and advises a recheck if a dog is still not using the limb after two to three weeks. If you are worried about how your dog is moving, our guide to limping after surgery covers what is normal.

Physio-Led Rehab and Muscle Rebuilding

With FHO, muscle is the joint's main support. Mar Vista Animal Medical Center puts it simply: lots of activity strengthens the muscles and builds a stronger false joint. That is why vets encourage early, controlled use of the leg rather than long periods of total rest.

A typical rehab plan may include:

• Passive range of motion: gently moving the hip through its range while your dog lies relaxed, to keep the new joint supple.
• Controlled lead walks: short and frequent at first, slowly building in length.
• Swimming or underwater treadmill: once the wound has healed, water lets the dog use the leg with less load.
• Strength work: as your vet or physio advises, such as slow sit-to-stands, gentle slopes and later stairs.

A qualified veterinary physiotherapist can tailor this to your dog, especially if they are larger, have arthritis in other joints or are slow to use the leg. If you are budgeting for sessions, our guide to the cost of dog physiotherapy in the UK covers the practical side.

Why Weight Matters So Much

The false joint is made of fibrous tissue rather than bone and cartilage, and it relies on muscle for support. Every extra kilo makes that job harder. Mar Vista notes that recovery can take longer in dogs that are over their optimal weight, and Southwest Veterinary Surgery lists weight reduction as part of the post-operative plan where it is needed.

Exercise is limited in the early weeks, so it is easy for weight to creep up. Ask your vet to weigh your dog at each check and adjust food portions while activity is restricted. Our guide to canine obesity and joint health explains the wider link.

What a Joint Supplement Can and Can't Do After FHO

It helps to be clear about where a supplement fits, so you can set realistic expectations.

When to Start a Supplement After FHO

The timing is your vet's call. They will consider how the wound is healing, which medicines your dog is on and whether their stomach has settled after surgery. Many owners raise it at the stitch-removal check. If your dog was already on a joint supplement before the operation, ask whether to carry on.

Once your vet agrees, MedPaw is given at 1 chew a day up to 4kg, 2 chews for 5 to 17kg and 2 to 3 chews for 18kg and over, doubled for the first three weeks. Give it alongside, not instead of, anything your vet has prescribed.

Long-Term Care After FHO

Most dogs do well after FHO. VCA reports that most recover fully and regain essentially normal use of the leg, though some lose a little range of motion. Southwest Veterinary Surgery adds that the outlook is generally good for small dogs and more variable in large breeds, and that surgery is not expected to restore completely normal function in every case.

To protect that result for the long term:

• keep your dog lean for life
• keep up regular, moderate exercise so the hip and thigh muscles stay strong
• watch the other hip and joints, which may have their own wear
• keep a steady daily joint supplement routine if it suits your dog
• book regular check-ups so your vet can spot muscle loss or stiffness early

If your dog had a total hip replacement rather than FHO, our guide to the best supplement after a hip replacement covers that recovery.

When to See Your Vet

Contact your vet promptly if, at any point after FHO surgery, your dog:

• has a wound that is red, swollen, hot, weeping or opening up
• is still not putting the foot down two to three weeks after surgery
• suddenly stops using the leg after a period of improvement
• seems in pain, restless, off their food or unusually quiet
• is losing muscle on the operated leg despite rehab
• has an upset stomach after starting any new supplement
