poor poor poor puppy. how can anyone let a pup at probably 3 weeks old leave their mother. i understand the feeling you might have when seeing these pups but this is exactly why this soort of breeders exist! your pup will mis his upbringing from his mother and his brothers and sisters. i hope that you can keep him alive as they are very vounerable at such a young age. here in holland there are people that sell pups out of the boot of their car. they come from countries as poland and hongaria and cost less than from a reputable breeder. they have many behavioral and health problems. but they look so sad..... people rescue the pup but don't realise that the seller will breed more of those pups because people buy them........
i hope all goes well with your puppy..............
