Do dogs know their siblings?
Dogs are pack animals.
Their parents and littermates are Their first pack.
If two littermate pups are adopted by neighbors and see one another regularly, the Dogs will recognize one another, they will adapt to the other dog (sibling) being a part of Their life without necessarily recognizing the familial connection.
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.
