Ohhhh....Poor Puppy, and your poor little boy!

How annoying the guy doesn't answer. If you knew the prefix of the dog (the breeder kennel name) then you could get in contact with them through the canine association in your state. They might even be another one to try.....even to find another Lab breeder that would be willing to help. I am sure they would too

Good luck finding a forever home for your wee puppy. So sorry it didn't work out for your family
