My German Sheperd has recently started limping on his rear leg and the vet said he would need surgery if it didn't get better, My husband gave him a rx 800 mg of ibuprofen a few times to help with his pain, Did this damage anything? or can it hurt him? he seems OK.
Yes, this could cause a problem. It can have serious gastointestinal side effects. Aspirin is much safer . The dose is 10 mg/kg. Vetcare
