Knowing what to expect at each stage of FHO recovery helps you stay on track, recognize when something's off, and avoid the two most common owner mistakes: doing too much too soon, or doing too little for too long.
FHO recovery is typically 8 to 12 weeks to functional recovery, and 3 to 6 months to full activity. Each phase has a specific focus and specific restrictions.
Quick answer: FHO recovery follows a four-phase progression: days 1 to 7 (pain control and early movement), weeks 1 to 4 (controlled walking and early strengthening), weeks 4 to 8 (progressive rehabilitation), and weeks 8 to 12+ (return to activity). Most dogs begin toe-touching within the first week and return to comfortable walking by weeks 6 to 8. Full running and jumping is typically cleared at 10 to 12 weeks.
Key takeaways
- Days 1 to 7: pain control and passive exercises are the priority. No free movement.
- Week 1 to 2: toe-touching expected. No weight-bearing by week 3 warrants a vet call.
- Weeks 2 to 6: leash walks increase by 5 minutes per week. Sit-to-stands begin.
- Weeks 4 to 8: hydrotherapy and hill walking introduced. False joint is actively maturing.
- Weeks 8 to 12: progressive return to normal activity. Off-leash cleared by vet only.
- Full running and jumping: 10 to 12 weeks minimum. Earlier risks muscular or joint injury.
Before you come home: preparation
Set up the recovery space before surgery day so it's ready when you arrive home.
Checklist:
- Crate or blocked-off small room with non-slip flooring (yoga mats or rubber-backed rugs)
- Ground-level bedding that doesn't require climbing
- Baby gates at the top and bottom of all stairs
- Water and food bowls accessible without stretching
- E-collar sized and fitted (confirm it extends past the nose tip)
- Ice packs or gel packs available for the first week
- All medications picked up from the pharmacy or vet
Days 1 to 7: early recovery
What's happening in the body
The incision is healing. Inflammation is at its peak in the first 2 to 3 days. The femoral shaft is held in position primarily by the surrounding muscles, as the fibrous false joint has not yet formed.
What to do
Pain medication: Give on schedule. Never skip.
Icing: Apply to the surgery site 2 to 4 times daily for 15 to 20 minutes. Wrap the ice pack in a light cloth. Don't apply ice directly to the skin.
Confinement: Crate or small room. Leash for all outdoor time. Carry the dog if stairs can't be avoided.
Passive range-of-motion (PROM): Begin within days 1 to 3 as instructed by your vet. 10 to 15 gentle flexion-extension cycles, 2 to 3 sessions daily.
Leash walks: Short trips for bathroom only. 5 to 10 minutes maximum. Slow pace on flat ground.
What's normal
- Sleeping most of the day
- Reduced or absent appetite for 1 to 3 days
- Holding the leg up or barely touching it to the ground
- Mild swelling at the incision
- Low energy
Milestone by end of week 1
The dog should be showing at least occasional toe-touching on the operated leg. Complete non-use of the leg beyond day 5 to 7 warrants a call to your vet.
Weeks 1 to 4: controlled walking and early strengthening
What's happening in the body
The false joint is beginning to form as fibrous tissue fills the space where the femoral head was removed. Muscle atrophy from the pre-surgical lameness period is significant. The incision heals and closes, typically by days 10 to 14.
What changes at weeks 1 to 2
- Leash walks increase to 10 to 15 minutes, 2 to 3 times daily
- Sit-to-stands begin: 5 repetitions, 2 to 3 times daily
- PROM continues: maintain daily sessions through weeks 1 to 4
- Suture removal at 10 to 14 days (first vet recheck)
Weeks 2 to 4
- Walk duration increases by 5 minutes per week: targeting 15 to 20 minutes per walk by week 4
- Sit-to-stands increase from 5 to 10 repetitions per session
- Gentle thigh massage 3 to 5 minutes once or twice daily
- Hydrotherapy may begin after suture removal if a facility is accessible
What's normal
- Limping on the operated leg during walking is expected throughout this phase
- Improvement should be visible week over week, though gradual
- Some swelling may persist in the thigh for 2 to 3 weeks
- The dog should be bearing weight on the leg regularly by week 3
Milestone by end of week 4
The dog should be walking with regular weight-bearing on the operated leg, even if limping. Leash walking at 15 to 20 minutes without worsening lameness post-walk. If the dog is still not bearing weight consistently, contact your vet.
For the care required at each stage of this period, see care required at each recovery stage.
Weeks 4 to 8: progressive rehabilitation
What's happening in the body
The false joint is actively maturing. Fibrous scar tissue is filling in and becoming more organized. Muscle mass is beginning to rebuild as the dog uses the leg more consistently. Range of motion in the hip is improving.
What changes at weeks 4 to 6
- Leash walks extend to 20 to 30 minutes, 2 to 3 times daily
- Gentle uphill walking introduced (gradual incline; not steep hills)
- Hydrotherapy: 2 to 3 sessions per week if available
- Balance exercises introduced: balance disc, cavaletti poles
Weeks 6 to 8
- Post-operative recheck with your vet, typically including reassessment of gait and hip function
- If the recheck is clear: supervised off-leash activity in a small, enclosed area may be permitted for short periods
- Walk duration continues to increase
- Sit-to-stands continue at 10 repetitions, 2 to 3 times daily
What's normal
- Noticeable improvement in gait quality compared to weeks 1 to 4
- The dog may start initiating use of the leg without prompting
- Some residual limping is still normal, especially after more active sessions
- Thigh muscle asymmetry (operated side smaller than non-operated side) is normal; this resolves with continued rehabilitation
Milestone by end of week 8
Most dogs are walking with consistent, reliable weight-bearing. Gait may still not be perfectly even, but the dog is using the leg as a matter of course rather than avoiding it. The 6 to 8 week recheck should show meaningful functional improvement.
For the physical therapy exercises that drive this phase, see physical therapy during the recovery timeline.
Weeks 8 to 12+: return to activity
What's happening in the body
The false joint is substantially mature. Muscle mass is rebuilding progressively. The dog's movement patterns are adapting to the new hip anatomy. Gait improvement continues as muscle strength increases.
What changes at weeks 8 to 12
- Walk duration reaches 30 to 40 minutes as tolerated
- Brief, supervised off-leash activity in secure areas is often appropriate if the 8-week recheck was positive
- Running and jumping remain restricted until specific vet clearance (typically 10 to 12 weeks at minimum)
- Hydrotherapy continues if available and beneficial
At 10 to 12 weeks
For most dogs, restrictions are fully lifted between 10 and 12 weeks post-surgery following a vet assessment confirming:
- Consistent full weight-bearing
- Good hip range of motion
- Adequate muscle mass on the operated side
- No pain on hip palpation
After 12 weeks
Some dogs, particularly large breeds or those with delayed recovery, benefit from continued structured rehabilitation beyond 12 weeks. Full muscle symmetry and the best possible gait quality may take 4 to 6 months of ongoing appropriate exercise.

Recovery timeline at a glance
| Phase | Timeline | Primary focus | Activity level |
|---|---|---|---|
| Early recovery | Days 1 to 7 | Pain control, icing, PROM | Crate rest; bathroom leash walks only |
| Early rehabilitation | Weeks 1 to 4 | Leash walking, sit-to-stands, PROM | Short controlled walks; no free movement |
| Progressive rehabilitation | Weeks 4 to 8 | Longer walks, hydrotherapy, hills, balance | Progressive controlled activity |
| Return to activity | Weeks 8 to 12 | Muscle building, gait normalization | Increasing activity with vet clearance |
| Full recovery | 3 to 6 months | Ongoing activity for muscle symmetry | Normal activity after vet clearance |
When recovery is slower than expected
Some dogs take longer than the standard timeline. Factors that extend recovery:
- Large body size (more load on the false joint, slower muscle compensation)
- Pre-surgical muscle atrophy (severe atrophy before surgery means more to rebuild)
- Delayed start to rehabilitation
- Inadequate pain management in the early phase
- Complications such as infection or excessive scar tissue
A dog who is not progressing at the expected rate should be reassessed by a vet. The most common corrections are adjustments to pain management, referral to a certified canine rehabilitation therapist, or hydrotherapy.

Frequently asked questions
My dog is walking normally at week 4. Can I let them off the leash?
No. Looking normal at week 4 doesn't mean the false joint is mature or the muscles are strong enough for uncontrolled activity. Running and direction changes at week 4 can damage the still-forming fibrous tissue and cause a setback. Continue with the structured timeline regardless of how the dog appears.
My dog refuses to use the leg at all after week 2. Is that a problem?
Yes. Consistent non-use of the leg beyond week 2 to 3 suggests either inadequate pain control or another issue. Contact your vet. The dog needs to use the leg for the false joint to form correctly. If pain is preventing this, additional pain management options exist.
When can my dog swim freely in a lake or pool?
Free swimming is typically permitted around 8 to 10 weeks after the incision is fully healed and the vet has cleared more active exercise. Controlled hydrotherapy (underwater treadmill) can begin after suture removal at 10 to 14 days. Unsupervised swimming in open water is a later-stage activity.
How do I know if my dog is doing too much?
The main signal is increased lameness after activity that doesn't resolve within 30 to 60 minutes. If your dog was walking well before a session and limping more afterward, reduce the session duration and intensity for the following week.
The FHO recovery timeline is not a test of your dog's toughness. It's a biological process with its own schedule. The false joint forms over weeks. Muscle mass rebuilds over months. Your role is to keep the process moving forward without outrunning it. Measured, consistent, patient progress produces better outcomes than either pushing hard or holding back.
