When our little beagle gets 'stoved up' from jumping down off my twin bed or from chasing little bunnies in our yard; we give him a "BABY" aspirin every 24 hours!!! Hubby puts it between cheese.
After about 5 days...our little Rebel has stopped his little whimpers of pain & back to his self. BUT he only weighs about 20 to 23 lbs.
I only know NEVER to give dogs chocolate or raisins or grapes!
Call your vet on how many per day you can give your dog :)
