Dogs are not silly, they can smell tablets and won’t just eat them out of your hand like it is a treat. Try breaking the tablets up and mixing in with their dog food. You can also try placing the broken pieces inside a piece of soft cheese, sausage even pate works. Some dogs will try and hide the pill in their mouth then spit them out, so watch them for a minute or so to make sure the pill has been swallowed. If your dog will not eat the broken tablets in any type of food, place the tablet on the very back of the dogs mouth and hold the dogs mouth shut until they swallow the tablet.
