One of the most important qualities to look for in a teacup Maltese puppy is health and genetic testing. Maltese are prone to several genetic problems, including joint, eye and liver issues.
People interested in buying a teacup Maltese puppy should make sure they are buying from a reputable, ethical breeder. The breeder should perform appropriate health testing of the parents. This testing is conducted through the Orthopedic Foundation for Animals and the Canine Eye Registry Foundation. Breeders who neglect this testing are more likely to produce puppies with serious and life-threatening problems.
Teacup puppies are also at a higher risk of other illnesses due to their small size. Infections, parasites and other normal puppy issues are more dangerous in a teacup Maltese. Owners should visit the breeder's facilities and make sure that they are clean and safe, and the breeder should get the mother and puppies adequate veterinary care and treatment.
It can be difficult to determine the personality of a young puppy, but owners should be aware that Maltese are prone to being difficult to train and housebreak. Owners should look for puppies that seem happy and outgoing. Maltese have a tendency to bark, so people looking for quieter dogs should look for one that seems less reactive to new sights and sounds. Buyers should always avoid lethargic or disinterested puppies, because this may be a sign of illness.
