I have never had a puppy longer then 16 weeks, but then again I only have pet quality pups and I sell them a lot less expensive then show people. If I did have a puppy longer I would not even think about doing that because, if a person can not afford to purchase one how would they be able to pay for vet bills and such. I know it sounds like a nice idea, but you really do what to worry about who gets your babies and whether or not they can take care of them.
I know this sounds mean, but I am concern about my puppies and need to know they will be taken care of.
