When giving your dog a tablet, gently take hold of his head from above, placing your thumb and finger on either side of the muzzle. Squeeze gently just behind the canine teeth. The dog's mouth should open.
Use your free hand to hold on to the tablet while lowering the dog's jaw. With the mouth open wide, place the tablet as far back on the tongue as possible, pushing it even further with your index finger.
Gently close and hold the muzzle while your dog swallows. You can encourage this by stroking the underside of the throat downward.
Finally give your dog lots of praise and a food reward each time he swallows a tablet.
If you follow these steps you will find that both you and your dog are much happier when it is medicine time.
