What is the cleanest house dog available?

The cleanest house dog available is a hypothetical concept, as the level of cleanliness of a dog depends on several factors such as the breed, individual habits, and the owner's grooming routine. However, some breeds are generally known for being relatively low-maintenance and easy to keep clean. These breeds include:

- Poodles: They have a low-shedding, hypoallergenic coat that requires regular brushing to prevent mats.

- Bichon Frises: They have a fluffy, white coat that is non-shedding and requires regular brushing.

- Maltese: They have a long, silky coat that is low-shedding and needs frequent brushing to prevent tangles.

- Shih Tzus: They have a long, double-coated that sheds moderately and needs regular brushing.

- Havanese: They have a soft, silky coat that is low-shedding and needs regular brushing to prevent mats.

It's important to note that any breed can be kept clean with proper care, including regular grooming, bathing, and cleaning the living area.
