Meloxicam is Advil similar to it?

Do not give these drugs to the ainimal it could kill him see a vet he will have the drugs for the dog

This sounds like it might possibly be arthritis. Ibuprofen (Advil) is rarly used in dogs, and should ONLY be used under the guidance of your veterinarian. Used improperly, ibuprofen can be highly toxic. Your Veterinarian may not recommend its use, as there are alternative veterinary drugs better suited for use in animals. Ibuprofen is not approved for use in animals by the Food and Drug Administration. Meloxicam has been tested and found TOXIC in dogs. You may however, use asprin in the following dose, provided your dog doesn't suffer from a heart condition, or gastric ulcer, until you can get into your vet. For chronic arthritis pain, we have prescription drugs that are much safer and far more effective.

To reduce stomach irritation, use buffered aspirin or give aspirin at mealtime. Giving your dog aspirin more often than twice a week is not a good idea.

Use 5 grain (325 mg) aspirin tablets.

A 60 to 80 lb dog may be given one tablet twice a day (every 12 hours) or 1/2 tablet three times a day (every eight hours). A 30 to 40 lb dog gets half as much; a 15 to 20 lb dog a quarter as much.
