If your dog is experiencing significant hip pain—whether from injury, arthritis, or hip dysplasia—your veterinarian may recommend surgery. Two of the most common options are Femoral Head Ostectomy (FHO) and Total Hip Replacement (THR).

While both procedures aim to reduce pain and improve mobility, they work in very different ways. Understanding the differences can help you make the best decision for your dog’s comfort, lifestyle, and long-term quality of life. We look at FHO vs THR in dogs.

What Is an FHO (Femoral Head Ostectomy)?

An FHO is a surgical procedure where the head and neck of the femur (thigh bone) are removed. Rather than restoring the joint, the body forms a “false joint” made of scar tissue and surrounding muscles.

This procedure eliminates bone-on-bone contact, which reduces pain.

When FHO Is Typically Recommended

  • Smaller dogs (though it can be done in larger dogs)
  • Dogs with hip fractures or severe arthritis
  • Cases where cost is a major consideration
  • Situations where a full hip replacement is not an option

What Is a Total Hip Replacement (THR)?

A Total Hip Replacement is a more advanced surgical procedure that replaces the entire hip joint with prosthetic components. This restores near-normal joint function.

When THR Is Typically Recommended

  • Medium to large breed dogs
  • Severe hip dysplasia or chronic arthritis
  • Active dogs who need full mobility
  • Cases where long-term function is a priority

THR is often considered the gold standard for restoring normal hip mechanics.

Key Differences Between FHO and THR

Understanding how these surgeries compare can help guide your decision.

  • Joint Function
    • FHO: Creates a functional but less stable “false joint”
    • THR: Restores near-normal joint function
  • Recovery Expectations
    • FHO: Requires significant muscle strengthening to compensate
    • THR: More natural movement once healed
  • Cost
    • FHO: Generally more affordable
    • THR: Higher upfront cost
  • Long-Term Outcome
    • FHO: Good pain relief, but variable mobility
    • THR: Typically excellent pain relief and function

The Role of Rehabilitation in Both Procedures

No matter which surgery your dog undergoes, rehabilitation is essential to achieving the best outcome.

For FHO patients, rehab is especially critical because the body must learn to function without a traditional joint. Strengthening muscles and improving mobility directly impact success.

For THR patients, rehabilitation helps:

  • Restore strength and balance
  • Improve range of motion
  • Prevent compensatory injuries
  • Support a safe return to normal activity

At Animal Rehabilitation Center of Michigan (ARC), we often work with dogs recovering from both procedures to help them regain comfort and confidence.

What Recovery Looks Like

Recovery timelines vary depending on the procedure and the individual dog, but most include:

  • Controlled activity and restricted movement early on
  • Gradual return to weight-bearing
  • Structured therapeutic exercises
  • Ongoing monitoring of progress

Rehabilitation therapies may include:

These therapies can significantly improve both speed of recovery and long-term outcomes.

Which Option (FHO vs THR) Is Right for Your Dog?

The best choice depends on several factors:

  • Your dog’s size and age
  • Activity level and lifestyle
  • Severity of hip disease or injury
  • Overall health
  • Budget considerations

Your veterinarian or surgical specialist can help guide this decision based on your dog’s specific needs.

Helping Your Dog Thrive After Surgery

FHO vs. and THR in dogs: both can dramatically improve a dog’s comfort and quality of life. With proper care, patience, and rehabilitation support, many dogs return to active, happy lives.

The key is choosing the right procedure—and supporting recovery every step of the way.

At Animal Rehabilitation Center of Michigan, we specialize in helping dogs recover after orthopedic procedures like FHO and total hip replacement. Our customized rehabilitation programs are designed to improve strength, mobility, and long-term comfort.
