Pet Arthritis Treatment: Every Option From NSAIDs to Joint Replacement and What Each Costs
Updated April 2026 · Based on veterinary orthopedic referral center pricing, ACVS data, and prescription pharmacy pricing
Osteoarthritis affects an estimated 20% of adult dogs over 1 year old and 80%+ of dogs over 8 years old. In cats, the numbers are even higher — up to 90% of cats over 12 show radiographic evidence of arthritis, though many are never diagnosed because cats hide pain effectively. This makes arthritis the most common chronic pain condition in companion animals and the single largest ongoing treatment cost for senior pets.
The treatment landscape has expanded significantly with the 2023 launch of Librela (bedinvetmab) for dogs and Solensia (frunevetmab) for cats — the first monoclonal antibody pain treatments approved for veterinary use. These monthly injections offer a new option for pets that can't tolerate NSAIDs or don't respond adequately. But they cost 2–3x more than traditional NSAIDs, raising the question every pet owner with an arthritic senior faces: which treatment combination provides the best pain relief at a sustainable cost over what may be years of management?
Treatment Options and Costs
| Treatment | Monthly Cost | Annual Cost | Details |
|---|---|---|---|
| NSAIDs (daily oral) | $25–$60/month | $300–$720 | Carprofen (Rimadyl), meloxicam (Metacam), deracoxib (Deramaxx). First-line treatment. Requires baseline bloodwork ($80–$150) and semi-annual monitoring ($80–$150). Long-term NSAID use carries liver/kidney risk — 1–3% of dogs develop adverse effects requiring medication change. |
| Librela/Solensia (monthly injection) | $80–$160/month | $960–$1,920 | Monoclonal antibody therapy (anti-NGF). Librela for dogs, Solensia for cats. Monthly vet-administered injection. The newest treatment option — launched 2023. No liver/kidney monitoring required. Effective in 70–80% of patients. Cannot be combined with some other pain medications. Higher cost than NSAIDs but growing rapidly in adoption. |
| Joint supplements | $20–$50/month | $240–$600 | Glucosamine/chondroitin, omega-3 fatty acids, green-lipped mussel. Evidence is modest — glucosamine/chondroitin shows moderate benefit in some studies, not conclusive in others. Omega-3s have the strongest evidence for anti-inflammatory effect. Not a substitute for pharmaceutical pain management in moderate-severe arthritis. |
| Physical therapy/rehabilitation | $50–$100/session | $600–$2,400 | Underwater treadmill, therapeutic laser, range-of-motion exercises, massage. Typically 1–2x/week for 6–8 weeks initially, then 1–2x/month maintenance. Underwater treadmill is the gold standard for arthritis rehab — reduces weight-bearing while building muscle. Insurance coverage varies. |
| Adequan injections | $40–$80/injection | $320–$640 | Polysulfated glycosaminoglycan. Loading dose: twice weekly for 4 weeks (8 injections = $320–$640), then monthly maintenance ($40–$80/month). The only FDA-approved disease-modifying osteoarthritis drug for dogs. Can be administered at home after vet training. Slows cartilage degeneration rather than just treating pain. |
| Surgical intervention (TPLO, FHO, joint replacement) | $3,000–$10,000 | One-time | Reserved for specific conditions: TPLO for cruciate ligament ($3,000–$6,500), femoral head ostectomy ($2,000–$4,000 for hip dysplasia), total hip replacement ($5,000–$10,000). Not elective for arthritis itself but for the underlying joint pathology causing secondary arthritis. Post-surgical rehab adds $500–$2,000. |
NSAIDs vs. Librela: The Central Cost Decision
For most arthritic dogs, the primary treatment choice is between NSAIDs (the established standard: $25–$60/month) and Librela (the new alternative: $80–$160/month). Over 3 years of treatment — a realistic timeline for a dog diagnosed with arthritis at age 8–10 — this decision represents a $1,980–$3,600 difference in total cost (NSAIDs: $900–$2,160 total vs Librela: $2,880–$5,760 total).
1) Dogs with liver or kidney compromise — NSAIDs are contraindicated, making Librela the only pharmaceutical option (the alternative is no pain medication, which is not acceptable for moderate-severe arthritis). 2) Dogs that vomit oral medications — Librela is an injection, bypassing GI issues. 3) Dogs where NSAIDs provide inadequate relief — adding Librela or switching to it may achieve better pain control. 4) Multi-pet households where daily pill administration is a compliance challenge — a monthly vet injection is harder to miss than a daily pill.
The Multi-Modal Approach: Combining Treatments
Veterinary pain management has moved toward multi-modal therapy — combining treatments with different mechanisms of action for better pain relief than any single treatment alone. Common combinations and their costs:
- Budget tier ($500–$1,300/year): NSAID + joint supplement + weight management. Effective for mild-moderate arthritis. The NSAID handles pain, supplements may slow progression, weight loss reduces joint load (every pound lost = 4 pounds less force on each step).
- Standard tier ($1,500–$3,000/year): Librela or NSAID + Adequan + physical therapy (initially). Adds disease-modifying treatment (Adequan) and targeted rehab. Most effective combination for moderate arthritis. The rehab component is frontloaded — intensive for 6–8 weeks, then maintenance.
- Comprehensive tier ($3,000–$5,000+/year): Librela + Adequan + ongoing physical therapy + supplements + laser therapy. For severe arthritis or high-value sporting/working dogs. Maximum pain relief at maximum cost. May also include gabapentin ($15–$30/month) for neuropathic pain component.
Weight Management: The Free Treatment That Matters Most
Every pound of excess body weight generates approximately 4 pounds of additional force on weight-bearing joints with each step. A 60-pound dog that's 10 pounds overweight experiences 40 extra pounds of force per step — thousands of times per day. The Purina Lifespan Study documented that lean dogs developed clinical arthritis signs 2–3 years later than mildly overweight littermates. Weight management is the single most impactful intervention for arthritis prevention and management — and it costs $0 (or actually saves money, since you're buying less food).

How much does arthritis treatment cost for dogs?
Mild arthritis: $500–$1,300/year (NSAIDs $25–$60/month + supplements). Moderate: $1,500–$3,000/year (Librela/NSAID + Adequan + initial rehab). Severe: $3,000–$5,000+/year (multi-modal therapy with Librela, Adequan, ongoing rehab, supplements). Surgical intervention for underlying conditions (cruciate ligament, hip dysplasia) is a one-time $3,000–$10,000. Over a 3-year management period, total arthritis costs range from $1,500 (mild, NSAIDs only) to $15,000+ (severe, comprehensive management).
Is Librela worth the cost?
Librela ($80–$160/month) costs 2–3x more than NSAIDs ($25–$60/month) but offers real advantages: no liver/kidney monitoring needed, no daily pill compliance issue, effective in 70–80% of dogs, and safe for dogs that can't tolerate NSAIDs. Over 3 years, the cost difference is $1,980–$3,600. Worth it if your dog can't take NSAIDs, doesn't respond adequately to NSAIDs, or if monthly vet injection is more manageable than daily pills. For dogs doing well on NSAIDs with normal bloodwork, switching to Librela purely for convenience is a significant cost increase.
