Ive been in contact with a breeder who has a 5 week old pup available. Right now the puppy weights 6.4oz. Not sure if thats an exact weight or an estimate. She said she was the smallest of the liter. Her parents are listed at 5lbs and 5.5lbs. According the growth chart, this dog might weigh 3lbs at the most. I'm worried about it having health problems. The parents seem to be normal size dogs and they are healthy.
What are your views on purchasing a puppy this small?

Shes just so cute. Idk if I can say no.
