Found this online:
Based on reactions in our canine patients, this is the ranking I would give
these medications: safest = acetaminophen (Tylenol tm), also safe =
aspirin, less safe = ibuprofen (Advil tm, Motrin Rx). However, this is
the ranking that I would give them based on the reports in the literature
and factoring in the likelihood of a bad reaction causing death: safest =
aspirin, also safe but less so = acetaminophen and less safe = ibuprofen.
The reason for these rankings include these things. Aspirin is reasonably
likely to cause gastric ulcers, which can be life threatening if ignored
but which respond to withdrawal of the medication. Acetaminophen doesn't
seem to cause ulcers but there are uncommon reactions to it in which liver
failure occurs and this may not respond to therapy, so death is a
possibility. Ibuprofen is very likely to cause ulcers, with 100% of dogs
developing ulcers with the use of ibuprofen in at least one study. On the
other hand, lots of my clients come in and tell me "I gave my dog an
ibuprofen last night" and I have only had to treat one or two cases of
ulcers and I can't recall a dog dying from this medication, yet.
