Physical Therapy and Hydrotherapy: Beyond Supplements

By Amanda Brooks, MS, CNS|Updated February 2026|5 min read

Here's something the supplement industry won't tell you: pills alone won't fix joint problems. After working with hundreds of arthritic dogs alongside rehabilitation veterinarians, I've learned that the most dramatic improvements come from combining proper supplementation with evidence-based physical therapy.

I've consulted extensively with Dr. Rebecca Torres, a certified canine rehabilitation practitioner (CCRP) in Seattle, and incorporated her protocols into my holistic approach to joint health. Supplements provide building blocks, but physical therapy provides the stimulus for healing.

Why Physical Therapy Matters

Arthritic dogs often enter a vicious cycle: pain causes decreased activity, decreased activity leads to muscle atrophy, muscle atrophy increases joint stress, and increased joint stress causes more pain. While joint supplements address inflammation and cartilage support, they can't break this cycle alone.

Physical therapy targets three critical goals:

Veterinary professional checking a dog
  • Maintain muscle mass to support and protect joints
  • Preserve range of motion to prevent stiffness
  • Improve proprioception (body awareness) to reduce injury risk

Hydrotherapy: The Gold Standard

Underwater Treadmill

Water buoyancy reduces weight-bearing stress by 60-80% depending on depth. An underwater treadmill allows controlled, low-impact exercise that would be painful or impossible on land.

A 2014 study in the Journal of Small Animal Practice followed 26 dogs with hip osteoarthritis through an 8-week underwater treadmill program. Dogs showed significant improvements in lameness scores and muscle mass compared to controls receiving only NSAIDs.

Dr. Torres recommends starting with 2-3 sessions per week, 10-15 minutes per session, with water depth at elbow level. As conditioning improves, duration can extend to 20-30 minutes.

Cost Reality: Professional hydrotherapy costs $40-75 per session in most areas. For dogs needing ongoing therapy, that adds up fast. I'll discuss home alternatives below that cost less while still providing benefits.

Swimming

Free swimming provides excellent cardiovascular exercise with zero impact. It's ideal for dogs who enjoy water and don't have respiratory issues.

The challenge: swimming is harder to control than an underwater treadmill. Dogs tend to use front legs more than rear legs when swimming, which may not target hind-end arthritis effectively. For hip dysplasia or stifle issues, underwater treadmill is generally superior.

For my Border Collie Finn with early elbow arthritis, I use swimming for general conditioning and reserve underwater treadmill sessions for targeted rehabilitation.

Land-Based Physical Therapy

Controlled Leash Walking

Don't underestimate walking. For many arthritic dogs, multiple short walks beat occasional long hikes. The goal is gentle, consistent movement that maintains mobility without triggering flare-ups.

Protocol I recommend:

  • Frequency: 3-4 walks daily
  • Duration: 10-15 minutes per walk for arthritic dogs
  • Pace: Slow enough that the dog doesn't limp during or after
  • Surface: Flat, even surfaces initially; gradually add slight inclines

Passive Range of Motion (PROM)

PROM exercises gently move joints through their full range without requiring the dog to bear weight. This maintains flexibility and can be done at home.

Dr. Torres taught me this technique: With your dog lying on their side, support the limb above and below the joint. Slowly flex and extend through a comfortable range. Perform 10-15 repetitions, 2-3 times daily.

Never force a joint past its comfortable range. If your dog shows signs of pain (tensing, pulling away, vocalizing), you've gone too far.

Sit-to-Stand Exercises

Simple sit-to-stand repetitions strengthen hindquarter muscles crucial for hip and stifle support. This is one of the most effective home exercises for rear-end arthritis.

Protocol:

  • Start on a non-slip surface
  • Use treats to lure into a sit, then immediately back to standing
  • Begin with 5 repetitions, building to 15-20
  • Perform 2-3 sets daily
  • Watch for proper form: the dog should sit squarely, not shifted to one side

Cavaletti Poles

Walking over low poles forces dogs to consciously lift and place their feet, improving proprioception and strengthening hip flexors. This is particularly valuable for dogs showing rear-end weakness or stumbling.

Start with poles flat on the ground, spaced at the dog's natural stride length. Gradually raise poles to 2-4 inches. Walk slowly through the pattern, allowing the dog to focus on foot placement.

Sample Weekly Schedule

This is the protocol I use for my senior Australian Shepherd with moderate hip arthritis:

Thursday15-min walk + PROMSit-to-stand (2x15)
FridayCavaletti + balance work15-min walk
SaturdaySwimming (if available)PROM only
SundayLight activity onlyRest day

When to Work with Professionals

Home exercises are valuable, but certain situations warrant professional rehabilitation:

  • Post-surgical recovery: After TPLO, TTA, or hip replacement, professional guidance is essential
  • Severe arthritis: Dogs who can barely walk need carefully calibrated programs
  • Neurological issues: Intervertebral disc disease, degenerative myelopathy require specialized approaches
  • No improvement after 4-6 weeks: Professional assessment can identify what's not working

Look for certified canine rehabilitation practitioners (CCRP) or certified canine rehabilitation therapists (CCRT). These professionals have completed extensive training in animal rehabilitation beyond standard veterinary or physical therapy degrees.

Combining Therapy with Supplementation

The best outcomes come from synergy. Glucosamine and chondroitin provide cartilage support. Omega-3 fatty acids reduce inflammation that limits exercise tolerance. Physical therapy provides the mechanical stimulus that supplements alone cannot.

I time my dogs' supplement doses around therapy sessions. Fish oil 30 minutes before hydrotherapy may help reduce exercise-induced inflammation. UC-II collagen works through immune modulation that complements the physical benefits of exercise.

Personal Observation: My Border Collie Finn showed the most dramatic improvement when I added twice-weekly hydrotherapy to his existing supplement protocol. Supplements alone helped, but the combination was transformative. Within 8 weeks, his willingness to jump and run returned to near-normal levels.
