Do dogs like their legs kicked when you scratch them?
Animal Planet offers this explanation: Dogs shake or kick their legs when you scratch them because of something known as the scratch reflex.
It's a completely involuntary reaction, which explains why your dog may look as puzzled as you do when it starts to happen.
Many believe it's instinctual behavior, harkening back to the days when your dog's wild ancestors would mask their scent to help them sneak up on their prey.
Wolves, for example, have been observed rolling in animal carcasses or the droppings of plant-eating animals, to cover up their own smell during the hunt.
Safe: Some Vegetables.
Your dog can have a healthy snack of carrot sticks, green beans, cucumber slices, or zucchini slices.
Even a plain baked potato is OK.
Don't let your dog eat any raw potatoes or any potato plants from your pantry or garden.
