Do dogs control their tails?
It's probable that individual dogs have their own unique tail-wagging language.
dogs can control their tails and their tail wags, but it appears they often start wagging out of instinct, not conscious thought.
It's kind of like a human frowning.
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.
