Just say no to acetaminophen for you puppy! It's toxic to dogs!
My Aussie has hip displaysia and before I put her on tramadol, she was on Ascriptin. It has aspirin in it. But, there are also some dangers with it to the stomach. My vet had me give it to her only 3 times a week. She weighs 51 lbs and I gave her only 1 tab. Knowing the risks, it was a chance I just couldn't continue to take, but I will give it to her if I notice she's having a particularly difficult time on a damp and cold day.
I wish you and your "puppy" (I call them all puppies) all the best!
