Do all female dogs have periods?
Unspayed cats and dogs will have a period – or more correctly – come into heat.
In female dogs, at the onset of heat, the vulva becomes quite swollen and will bleed.
Some bitches bleed so much they will leave spots of blood all over the house.
Dogs cycle anywhere from every 4 months to once every 12 -16 months.
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.
