This leads us to ask, can dogs take omeprazole? The answer is yes, but this doesn't mean we should just take a pill out of our medicine cabinet and give it to the dog. At AnimalWised we detail everything you need to know about omeprazole for dogs, paying specific attention to its dosage, usage and side effects. Before we do, we remind you that any drug given to your pet should be first authorized by a qualified veterinarian.
