This is the sad, and controversial, part of this breed. This is also why it is important to do some research on your chihuahua breeder before you buy any chihuahua puppies. Breeders try and create these cute teacup chihuahua puppies by taking the runts of their litters and barely feeding them. They feed the little dogs enough to keep them alive, but hope to stunt their growth so they stay very small. They are already the runts of the litter and very small as puppies. After this, they take these malnourished, tiny chihuahuas and breed them. The end result is what the breeders hope is a litter of runts. Anyone with a heart would find this practice despicable and should be punished.Should I buy a Teacup Chihuahua?
This is a tough question to answer, and the answer is maybe. You definitely should not buy a teacup chihuahua from these breeders that try and create them. In addition to supporting the breeders harsh industry, these dogs are not healthy. They are generally malnourished which can cause a whole host of problems. In addition, they can suffer shortened life spans and other health problems later in life because of the extreme dwarfing. It is not healthy for a normal teacup chihuahua that is that small to be bred even if it did not suffer from all of these harsh conditions. In fact, chihuahua breeding is one of the most problematic dog breeds because of their small size to begin with. However, it is possible to find health, small chihuahuas that were just the runt of a healthy litter. They can still be tiny, and very healthy and happy dogs. It is important to buy from a responsible breeder that does not engage in these shady activities.
