Bichon Frises are small breed dogs, and they are permitted to be kept as pets in Suzhou. The reason why not many people own Bichons is mainly due to their tendency for matted fur and their relatively sensitive digestive systems.

Generally, in Suzhou, small breed dogs with an adult height of 35 centimeters or less (including 35 cm) are allowed to be kept as pets. Adult Bichon Frises typically measure between 20 and 30 centimeters in height and weigh less than 5kg, classifying them as small dogs. Therefore, they are permitted in Suzhou. What some people refer to as "mini" or "large" Bichons are often not purebred and are likely mixed breeds. It is important to note that guide dogs and service dogs for visually impaired or disabled individuals living in the urban areas of Suzhou are exempt from the 35-centimeter height restriction.
Why Aren't Bichons More Popular?
1. Bichon Frises' coats are prone to tangling, splitting, and attracting dirt, which can lead to the development of mites, fleas, and other parasites. Owners need to groom their Bichons frequently and bathe them regularly, which can be a tedious task for some.
2. Bichons are known for being sensitive and suspicious by nature, sometimes even a little neurotic. Some Bichons can also be short-tempered, have sudden outbursts, and may even bite their owners when agitated. Additionally, Bichons may exhibit a tendency to jump on people, especially when they are in heat.
3. Another reason why Bichon Frises may not be as popular is their relatively weaker constitution as a small breed. They need regular vaccinations because they are more susceptible to diseases such as canine distemper, parvovirus, and gastroenteritis than larger breeds.
