THR recovery is fundamentally different from FHO recovery. Where FHO encourages early movement to form the false joint, THR requires strict rest in the early phase to allow the implant to osseointegrate: to bond with the surrounding bone.
Getting the recovery wrong in THR carries higher stakes than in FHO, because the consequence of premature activity isn't just a slower false joint. It's potential implant loosening or luxation that may require surgical revision.
Quick answer: THR recovery involves three phases. Weeks 1 to 4: strict crate rest with leash-only bathroom trips; no running, jumping, or stairs. Weeks 4 to 12: progressive leash walking, increasing from 5 to 20 minutes. Week 12 to 16: return to normal activity with vet clearance. Most dogs walk normally by week 14. Full activity including running and free play is typically permitted at 14 to 16 weeks post-surgery.
Key takeaways
- Weeks 1 to 4 are strict rest: no running, jumping, stairs, or off-leash activity.
- Most dogs bear weight within the first week on the new implant.
- Texas A&M protocol: 5-minute leash walks from week 4, increasing 5 minutes per week.
- Implant luxation risk is highest in the first 6 to 8 weeks: activity restriction is not optional.
- 14 weeks is the typical milestone for lameness resolution.
- Annual radiographic monitoring is required for the rest of the dog's life.
The first 24 to 72 hours: in the hospital
Most dogs undergoing THR are hospitalized for 1 to 3 days after surgery, sometimes up to 5 days. This is longer than FHO, reflecting the greater complexity of THR and the need for more intensive early monitoring.
During hospital recovery:
- Continuous pain management through injectable and then oral medications
- Monitoring of the surgical site for bleeding, swelling, or discharge
- Assessment of the dog's neurological status (sciatic nerve runs near the hip)
- Radiographs taken immediately post-operatively to confirm implant position
- Initial weight-bearing assessment
Most dogs begin tentative weight-bearing on the new hip within the first 1 to 3 days, which reflects the immediate stability of the implant. Arizona Canine Orthopedics notes: "Your dog's walking should improve daily."
Coming home: immediate priorities
When your dog is discharged, you'll receive detailed written instructions specific to your surgeon's protocol. The most important immediate priorities:
Pain management: Give all medications on schedule. Pain control in the early weeks directly influences how comfortable the dog is during the critical rest period. Never skip doses.
E-collar: Must be worn at all times until the incision is fully healed (10 to 14 days). Licking introduces bacteria to the surgical site and risks implant infection, which is catastrophic in THR.
Incision monitoring: Check daily for redness, swelling, or discharge. The incision must stay dry. No bathing until cleared.
Home setup before surgery day:
- Non-slip rugs or mats throughout the dog's movement area
- Ramp for car entry/exit (no jumping on or off anything)
- Baby gates blocking all stairs for 6 to 8 weeks
- Crate or exercise pen for supervised confinement
- Ground-level sleeping area; no furniture access
Weeks 1 to 4: strict activity restriction
This is the most important phase of THR recovery. The implant is integrating with the bone during this period, and premature loading or impact can prevent osseointegration or cause the implant to shift position.
Global Vet Specialists is explicit: "INADEQUATE RESTRICTION OF ACTIVITY IS A COMMON CAUSE OF POSTOPERATIVE COMPLICATIONS AND INCREASED VETERINARY COSTS."
What is permitted:
- Crate rest or small room confinement when unsupervised
- Short, slow leash walks on a 6-foot leash for bathroom trips only
- Non-slip surfaces at all times
What is strictly prohibited:
- Running or trotting
- Jumping on or off anything (including furniture, car, steps)
- Stairs (carry the dog or use a ramp for unavoidable situations)
- Off-leash activity
- Rough play or interaction with other pets
Managing a restless dog: Many dogs feel significantly better within 1 to 2 weeks of THR because their chronic pain has been removed. They want to run and play. This is the most dangerous time for the implant. Mental enrichment through puzzle feeders, scent games, and training helps substitute for physical activity. Sedatives prescribed by your vet are appropriate if the dog is consistently difficult to keep calm.
Weeks 4 to 8: beginning controlled exercise
After the 6-week recheck confirms early healing, the walking program begins.
Texas A&M protocol: "After the first four weeks of crate confinement, slow five-minute leash walks are allowed two to three times a day. These leash walks are increased by five minutes each week until they are 20 minutes long."
Arizona Canine Orthopedics protocol: "Home care must be limited to slow and brief, leash-controlled walks for 4 weeks. One month after surgery, leash walking may be gradually increased to up to 20 minutes over the next 4-week period."
Walk guidelines during this phase:
- Flat, even ground only (avoid rough terrain or steep gradients)
- Slow pace to encourage weight-bearing on the operated leg
- 6-foot leash maximum length
- Stop if the dog is significantly more lame after the walk than before
Still prohibited through week 8:
- Off-leash activity
- Running or trotting
- Jumping
- Stairs (supervised only if unavoidable, using a ramp where possible)
Weeks 8 to 12: progressive rehabilitation
The 8-week recheck with radiographs confirms the progress of osseointegration. If the recheck is clear, activity increases further.
Walk duration: 20-minute leash walks, 2 to 3 times daily, maintained through week 12.
Physical therapy: This phase is when formal rehabilitation exercises are most beneficial:
- Passive range-of-motion exercises: gentle hip flexion and extension, maintaining joint mobility
- Sit-to-stands: targeted quadriceps and hip extensor strengthening
- Controlled uphill walking: engages the hip extensors more effectively than flat walking
- Hydrotherapy (if available): underwater treadmill allows full muscle engagement without joint impact; excellent for muscle rebuilding in this phase
VCA Animal Hospitals: "Physical rehabilitation with a qualified canine rehabilitation practitioner should begin shortly after surgery."

Week 12 to 16: return to activity
The 12-week recheck is the major milestone. Radiographs assess full osseointegration and implant stability. If results are favorable:
- Off-leash activity in a secure area may begin
- Free play and running are gradually permitted
- Stairs are typically cleared
- Swimming is often permitted or encouraged
Arizona Canine Orthopedics: "Dogs are allowed to resume normal activities at approximately 14 to 16 weeks following surgery."
Full return to vigorous activity (for working dogs, competition, extended athletic activity) should be discussed with your surgeon specifically. Global Vet Specialists notes some strenuous activities should be avoided for life: those where the dog may jump and land with all weight supported by the hind legs.

Signs of complications: when to call
| Sign | Urgency |
|---|---|
| Sudden worsening of lameness after improvement | Call surgeon promptly |
| Clicking or grinding sound from the hip | Call surgeon |
| Dog completely non-weight-bearing after 1 week | Call surgeon |
| Spreading incision redness, discharge, odor | Call same day |
| Dog reluctant to bear weight on the opposite leg | Assess for compensatory injury |
| Fever, lethargy, reduced appetite beyond day 3 | Call surgeon |
Luxation (the prosthetic ball coming out of the socket) is the most serious early complication. Signs include sudden severe lameness, the leg appearing shorter or in an abnormal position, and obvious pain. This is a surgical emergency: contact your surgeon or emergency vet immediately.
Dr. Buzby ToeGrips: "If your dog is limping after a total hip replacement, it is important to speak with your veterinary surgeon right away."
Long-term monitoring: annual rechecks
THR recovery doesn't end at 16 weeks. Annual radiographic monitoring throughout the dog's life allows early detection of:
- Implant loosening (particularly with cemented systems)
- Bone resorption around the implant
- Wear changes in the polyethylene liner
- Any compensatory changes in the opposite hip, stifles, or spine
Global Vet Specialists protocol: "Checkups are completed at 10 to 14 days after surgery, at 6 weeks, and annually thereafter. Both the six-week and annual checkups will consist of an examination and radiographs."

Frequently asked questions
Why does THR require such strict rest when FHO encourages early movement?
The mechanisms are opposite. FHO creates a scar tissue false joint that forms in response to movement. THR places a precision-engineered implant that must form a stable bond with the bone (osseointegration) before it can be loaded. Premature activity prevents osseointegration and risks the implant shifting, which can require revision surgery.
My dog is walking fine two weeks after THR. Can I let them off the leash?
No. Looking fine is not the same as being healed. Osseointegration takes 6 to 8 weeks to establish adequately. A dog who appears comfortable at two weeks is walking on an implant that is not yet fully bonded to the bone. Off-leash activity at this stage risks luxation or loosening.
Can my dog use stairs during recovery?
Not during the first 6 to 8 weeks. After the 6-week recheck, your surgeon will advise when stairs are appropriate. A ramp is the preferred solution during the restriction period. If stairs are unavoidable, carry the dog for the first several weeks.
What if my dog refuses to rest?
Talk to your vet about sedative support. Many practices prescribe mild sedatives during the strict rest phase specifically for this scenario. Puzzle feeders, scent games, and calm indoor training are the most effective behavioral strategies. A dog that cannot be confined safely is a genuine complication risk.
THR recovery asks a lot of both the dog and the owner. The activity restrictions are demanding, the timeline is long, and the stakes for getting it wrong are real. But the outcome data for dogs who follow the protocol correctly is among the most positive in veterinary orthopedics. The investment of 16 weeks of careful recovery is what produces the years of pain-free function that the surgery promises.
