Arthritis in dogs
Osteoarthritis affects a large share of older dogs and many younger large-breed dogs. Treatment is a combination: weight control, an anti-inflammatory, a nerve-pain drug, joint supplements and sometimes newer injectables. Some of these are human generics a pharmacy fills for cash; the main anti-inflammatories are veterinary products.
What it is
Arthritis in dogs is the gradual breakdown of joint cartilage, usually in hips, elbows, knees and the spine, driven by age, body weight, breed and old injuries such as cruciate ligament tears. Dogs rarely cry out; they slow down on walks, hesitate at stairs, struggle to rise, lick a joint or become irritable. By the time stiffness is obvious the disease is well established.
Vets diagnose it by examination and X-rays, and treat it as a long-term condition to be managed rather than cured. Keeping the dog lean is the single most effective measure, because every extra kilogram loads the joints; controlled exercise, physiotherapy and hydrotherapy follow. Medicines are layered on top, starting with an anti-inflammatory and adding others as needed.
How it is treated
The non-steroidal anti-inflammatories are the foundation: carprofen, meloxicam, deracoxib, firocoxib and grapiprant are all veterinary products dosed by weight, given with food, with liver and kidney blood tests before and during long-term use. Human meloxicam tablets are sometimes prescribed for larger dogs because the lowest human strength suits a bigger animal.
Gabapentin is added for the nerve-pain component and for dogs that cannot take an NSAID; it is a human generic. Tramadol was once routine but is now used less because its benefit in dogs is uncertain. Amantadine, another human generic, is used for chronic wind-up pain. Joint supplements with glucosamine, chondroitin and omega-3 fatty acids have modest evidence and are safe; prescription joint diets concentrate the same ingredients.
Newer options are given at the clinic: monthly injections of an antibody against nerve growth factor, and polysulfated glycosaminoglycan injections. For a dog with one badly affected joint, surgery including replacement is possible.
What an owner pays cash for
A dog with arthritis typically costs its owner a veterinary NSAID every month for life, which is the largest item and is bought from the vet or a pharmacy stocking veterinary products, plus gabapentin and sometimes amantadine, both cheap human generics that any pharmacy fills, plus supplements and diet. Where the generic carprofen or meloxicam is dispensed rather than the brand, and the human generics come from a flat-price pharmacy on ninety-day prescriptions, the monthly outlay changes considerably without any change in treatment.
The medicines, one guide each
- CarprofenVet-only
Carprofen (Rimadyl and its generics) is the most prescribed anti-inflammatory for dogs with arthritis and after surgery. It is a veterinary-only drug with no human equivalent, so it is sold through vets and pharmacies that stock veterinary products rather than filled from a human pharmacy’s shelves.
- MeloxicamPharmacy can fill
Meloxicam is the most prescribed anti-inflammatory for arthritis and post-surgical pain in dogs. The veterinary liquid is dosed by weight; human meloxicam tablets contain the same drug and are sometimes used for larger dogs. In cats its use is tightly restricted because repeated doses can damage the kidneys.
- GabapentinPharmacy can fill
Gabapentin is one of the most prescribed medicines in small-animal practice, for chronic pain, nerve pain, seizures and, in cats, for anxiety before vet visits. It is a human generic, so a vet’s prescription can be filled at an ordinary pharmacy, with one important caution about the liquid.
- AmantadinePharmacy can fill
Amantadine is a human drug that vets add to an anti-inflammatory or gabapentin for dogs and cats with chronic pain that has become amplified in the nervous system, typically long-standing arthritis or cancer pain. It is a generic that any pharmacy can fill, and the capsule and the liquid are priced very differently.
- TramadolPharmacy can fill
Tramadol is a human pain medicine that vets prescribe for dogs after surgery and for chronic pain, usually alongside an anti-inflammatory. It is a controlled substance, which affects how prescriptions are written and filled, and any pharmacy that dispenses it for people can fill a vet’s prescription.
Questions for your vet
- What is my dog’s ideal weight, and what diet gets there?
- Which anti-inflammatory, and what blood tests before and during?
- Would gabapentin or amantadine help alongside it?
- Can the prescription be written for the generic NSAID and for human generics where appropriate?
- Is the monthly injectable worth discussing for my dog?
