How Rimadyl Works
Rimadyl works by blocking enzymes called cyclooxygenase (COX).
These enzymes produce substances known as prostaglandins, which cause inflammation and pain.
By reducing prostaglandin production, Rimadyl helps:
• Decrease inflammation
• Reduce swelling
• Relieve pain
• Improve joint mobility
This mechanism makes Rimadyl particularly effective for arthritis pain in dogs.
Rimadyl Dosage for Dogs
The correct dosage of Rimadyl depends on your dog’s body weight, age, and health condition.
Veterinarians typically prescribe:
2 mg per pound (4.4 mg/kg) per day
This dosage may be given:
• Once daily
or
• Divided into two smaller doses
Rimadyl is available in several forms:
• Chewable tablets
• Caplets
• Injectable solution (used by veterinarians)
Never adjust the dosage without consulting your veterinarian. Rimadyl for Dogs
