What did the vet say? he would know more. That does seem small for a breed such as that .Is the doberman full size breed? Six weeks is average to be taken from litter and weaned though.I just got a 6 1/2 week old puppy boxer/doberman x, and when i took him to the vets, he only weighed in @ 2.5 lbs. doesnt that seem small or is it just me? any advice? i have a pic if you want to see
