Small and teacup breeds of dogs are very high maintenance. They need to be fed several small meals a day due to having tiny stomachs. Plus, they are almost impossible to housebreak like a normal dog because of their tiny bladders. They are also incredibly fragile and could easily get hurt or even die from small falls like off your couch. People tend to want these kinds of dogs because they are incredibly cute, but they have no idea what they are in for.
