Can you give your 70 lb collie one half of an Advil tablet?

No but you can give them a childrens aspirin or half of an adult aspirin

AnswerThe best thing to do is ask your vet. I have been breeding and raising dogs for my whole life. I have never instructed as a vet tech for the Army, or had my vet instruct me to give my dog something as strong as Advil. At the most I have given a baby aspirin, 1, or even a half of one, depending on the size of my dog. But then again, only on the instructions of my vet. You should do the same. You don't want to poison your pet.
