How to use: First, take out the puppy and other pets from the set. Use the pet bowls to 'feed' them. Then, use the veterinary and grooming equipment to check and groom the pets. You can also use the X - ray cards to 'diagnose' what's wrong with them. Let the pets rest in their houses. For storage, close the expandable wall and ground floor. Carry it around by holding the roof handle. Note: Keep small parts away from children under 3 to avoid choking hazards. When not in use, store it in a dry place to prevent damage. If any parts get dirty, you can gently wipe them with a damp cloth.
