Puppies are prone to water shortage during menstruation. Dog owners can add their favorite honey to their drinking water to make themselves more fond of drinking water. You can also prepare some liquid food to supplement the puppy's nutrition. You can feed goat milk powder and rice porridge, or you can soak dog food until it is soft and feed it to the puppy, or add a proper amount of nutritional cream to supplement it. If the owner has free time, he can use his free time to cut some chunks of strawberries and watermelons for the dog as dessert.
