When your dog is in pain, it’s natural to want to help. Many pet owners wonder if human medications like aspirin can be safely given to dogs. While low-dose aspirin can sometimes be used for canine pain relief under veterinary supervision, there are important safety considerations every dog owner should know.
Understanding Aspirin Use in Dogs
Aspirin (acetylsalicylic acid) is a nonsteroidal anti-inflammatory drug (NSAID) that can provide pain relief and reduce inflammation in dogs. Veterinarians may occasionally recommend it for:
-
Temporary pain management
-
Mild arthritis discomfort
-
Post-surgical inflammation
-
Other conditions where NSAIDs are appropriate
However, aspirin is not FDA-approved for use in dogs, and veterinary-specific NSAIDs are generally preferred due to their better safety profiles.

Recommended Aspirin Dosage for Dogs
The generally accepted aspirin dosage for dogs is 5-10 mg per pound of body weight given every 12 hours. This means:
-
A 10 lb dog would take 50-100mg every 12 hours
-
A 30 lb dog would take 150-300mg every 12 hours
-
A 60 lb dog would take 300-600mg every 12 hours
Important notes:
-
Never exceed 30mg per pound in a 24-hour period
-
Always use the lowest effective dose
-
Treatment duration should typically not exceed 5 days without veterinary approval
Low-Dose (81mg) Aspirin for Dogs
Many owners consider using low-dose “baby” aspirin (81mg) for smaller dogs because:
-
Easier to divide doses for small breeds
-
Lower risk of overdose
-
More precise dosing
However, even low-dose aspirin carries risks and should only be used under veterinary guidance.
