Carprofen Dosage for a 70 lb Dog

The FDA-labeled dose for carprofen in dogs is approximately 2 mg per pound (4.4 mg/kg) total per day, given as a single dose or split into two doses 12 hours apart. For a 70 lb (31.8 kg) dog, this gives a range that a licensed vet will narrow down based on the indication, your dog's age, kidney/liver function, and any other medications. RexVet vets serve Florida, New York, and Virginia and can calculate the right dose for your specific dog in a $64.99 video visit.

Carprofen (carprofen) is widely used in dogs in the 70 lb range, but "safe" depends on the specific dog, not just the weight. Large breeds carry higher rates of orthopedic disease (hip dysplasia, cruciate ligament rupture, arthritis) — making pain management drugs more frequently prescribed. They also have higher rates of cancer, which can affect both drug choice and dosing for many medications. A licensed vet will check your dog's history, current medications, and any underlying conditions before prescribing.

The most common things to watch for are: Decreased appetite, vomiting, or diarrhea — call your vet same day; Black, tarry, or bloody stool (possible GI ulceration — urgent); Yellow gums or eyes (possible liver issue — urgent). If you see anything concerning, contact a vet. For large dogs specifically: Large breeds carry higher rates of orthopedic disease (hip dysplasia, cruciate ligament rupture, arthritis) — making pain management drugs more frequently prescribed.

If the veterinarian decides it is appropriate after a video visit, they can prescribe it where state rules allow.

RexVet’s veterinarians are licensed in all three states and take Carprofen refill requests where state rules allow for dogs already established on the medication. Refill visits are also $64.99. Prescriptions are filled through RexVet's in-house pharmacy (RexVetRx) or can be sent to your local pharmacy.
