It's just a sales gimick. I have seen some breeders refer to 4 and 5 pounds as teacups. If you buy from a reputable breeder you will get a nice small dog that is healthy and not overly fragile.
Those micro minis as some breeders are now calling them have hormonal issues, as another person posted, and just as with abnormally small people they have a decreased life expectancy. They also require a lot of sleep and frequent meals. So the majority of their day can be spent eating and sleeping.
It was very wise of you to ask and not fall for some sales pitch. |
