Recommend you raise a Bichon Frise, small-sized, convenient to carry when going out, very smart, and very cute. If cared for well, it definitely won't get sick; my dog has never been sick.
Among small dogs, Bichons and Poodles (many people like to dress Poodles as Teddies, so many call them Teddies online) are the most popular to raise. They have no body odor and don't shed hair, are very smart, and are very clingy but not noisy. Both of these dogs require frequent grooming, which is a relatively costly item.
Schnauzers also don't shed much, look a bit like little old men, have very long eyelashes, and look quite good if dressed up as Mickey Mouse.
Schnauzers do not need grooming very frequently, basically combing every 2-3 days; Poodles, because of their curly hair, need combing every 1-2 days, otherwise their hair will tangle; every 1-2 months a haircut is needed, that is, going to a pet shop for grooming to get a stylish look to be beautiful.
Next is the Chihuahua. This dog is too small; I often worry about accidentally stepping on or pressing it, and they are very timid and bark a lot. Personally, I don't like them very much.
Pomeranians have low requirements for living environments, making them very suitable for city dwellers living in narrow spaces indoors. They are small in size, light in weight, require little exercise, are highly trainable, friendly to other animals, adapt well to cities, cold-resistant, and suitable for adult families or families with older and mild-tempered children. Pomeranians must be groomed regularly and are not suitable for busy people.
Cute and alert, they are not only for play but also serve as watchdogs.
Disadvantages: low adaptability when first raised, too excitable, noisy, low friendliness to children and strangers.
Medium-sized dogs include Shetland Sheepdogs or Border Collies, both very smart, especially Border Collies, but they are very naughty and energetic, hard for ordinary people to handle, so the smaller Shelties are more affectionate.
Also there are Corgis (these are tailless, Queen Elizabeth likes them a lot), Pugs, Miniature Deer Dogs, and Dachshunds, all small and short-haired.
Regarding price, it mainly depends on pedigree; better pedigree equals higher price. If your budget is limited, do not consider dogs that require grooming, as grooming fees are expensive.
As for being not easy to get sick, that depends on the owner's care and the dog's individual constitution. If the owner takes good care, the chance of illness will be much lower. For example, vaccinations must be given regularly, reducing the possibility of parvovirus and distemper; internal and external deworming regularly; choose better dog food, avoid giving things like chicken bones or salty food indiscriminately.
My dog started from 1 year old and now is 6 years old; except for vaccinations, never needed a visit to the vet, very healthy, which also saves money.
If you are satisfied with my reply, please give a positive review. Thank you.
