I know years ago, my vet said Entrophen Tablets were safe to feed to my dog. I have not needed to use it again since, and that was many years and several dogs ago. So I looked online to see what is safe to feed to dogs, and of all the "people" meds, they say Aspirin (buffered/coated) is best and safest. I was looking for dosages, and found one that said 5-10 mg per pound, which would have made it 50-100 mg for a 10 pound dog. I went and gave 1 full 81 mg coated (low-dose) aspirin to my 10 pound Chinese Crested/Chihuahua cross, thinking it would be safe because is right in the middle of the suggested dose. I went back to my computer and read another site's information, and it said one 81 mg aspirin was enough to treat a 30-35 pound dog! I just about crapped, because if that is the case, I have just given my baby 3 times the proper dosage!! Does anyone know for certain what is the proper weight dosage??
