Pomeranians, like all dogs, require regular grooming and maintenance to keep them clean and healthy. Pomeranians have a thick, double coat that sheds moderately throughout the year, with heavier shedding during seasonal changes. This can result in some hair around the house if not regularly brushed or groomed. Additionally, Pomeranians are known to be prone to dental issues, so it is important to maintain their oral hygiene through regular teeth brushing and check-ups with a veterinarian. Overall, while Pomeranians may require some upkeep and maintenance, they are not typically considered to be excessively messy pets.
