How Does That Grab You?
As you pet your dog, gently grab some skin and wiggle it. Praise him; then release and praise some more. Wasn't that fun? When he accepts this happily, grab more quickly and firmly but never harshly. This is not supposed to be painful. Give him a treat! Soon your dog will associate this type of grabbing with fun.
How About a Hug?
An affectionate gesture among us humans, this is an “attack” to dogs and is best discouraged between child and dog. Dogs learn to tolerate it from us but few really love it. But, just in case, prepare your dog. While your dog is relaxed, give a quick, gentle hug; then release. Praise! Always release before the dog gets frightened or uncomfortable. Work up to a ten to twenty-second hug, praising while hugging then release calmly.
Don't rush him. Make this fun. If he pulls away, then for three days give him attention ONLY when you are gently and briefly hugging him. If at any time your dog growls, stiffens or lifts a lip, stop and find a qualified trainer or behaviorist to give you hands on guidance.
Surprise!
Do the unexpected. Dog walking up the stairs in front of you? Hold his tail gently as you walk up behind him. Instead of petting his head, hold an ear or a paw. Teach him to expect the unexpected and children will come as no surprise.
Reminder:
As with all of training like this, please do it out of sight of children.
We do not want your children imitating you.
