Only you can decide there is normally always one smaller one in a litter we sold one and he was nicknamed mini cooper cos he was small he is now quite a big boy. You are the only one there to be able to assess whether you think the puppy is healthy and sound if in doubt ask the breeder to take the pup to the vet for a vet health check although only valid for 24 hrs at least your mind will hopefully be at rest, expect to pay the vets fee unless you have a very good breeder!!!!

We no longer refer to them as runts but as the smaller ones it sounds nicer!!!!

good luck with what you decide
