If you continue sharing a home, make sure your dog’s area is always clean and well-kept. Keeping the dog’s belongings like bedding, food bowls, and toys in their own designated space can go a long way in maintaining order and hygiene. By doing this, you’re not only respecting your sister’s need for cleanliness but also showing her that your dog doesn’t impact the hygiene of the rest of the house.
