I am a small breeder, my dogs are loved, walked, and live in the house.
All litters are whelped in the living room, and are brought up in there.
They are used to children my 2 year old grandson plays with them and are all in pens , not in cages!
We encourage the new owners to bond with the puppy before it goes to the new home.
Also that gives me time to see if you are suitable for the puppy too. Also i like to keep in touch with the new owners with photos, and plenty of advice.
