Is it possible you are confusing Rimidayl with another drug. Rimidayl is an anti inflammatory used for arthritis, post surgery pain killer etc. Please understand i’m not saying someone should use it or not use it, I’m just trying to add information.It does have side effects and I would use it on an older dog that had an underlining health issue such as cancer. But not on an 8 year old dog with a lot of life left. I can't figure out why some on here are suggesting giving Rimadyl for a dog that doesn't have any known problems other than being over weight. The dog isn't sick it has just been short sided as far as exercise and food goes. Medicine would be the last thing I would suggest. https://www.fda.gov/animal-veterina...ell-clients-about-pain-control-and-their-pets
Quote from my veterinary medicine for dummies book
Rimidayl is one of the brand names for the veterinary drug carprofen. Carprofen belongs to a group of drugs called NSAIDs, or nonsteroidal anti-inflammatory drugs. These drugs act to reduce inflammation with fewer negative side effects than steroids, making them more suitable than steroids for long-term use.
Carprofen is safer for use in dogs than human NSAIDs such as ibuprofen, naproxen, or aspirin, which is why it is one of the more commonly prescribed veterinary canine painkillers”
