Either that pup is not pure GSD, or that pup is more like 3.5 weeks or 4 weeks old, or maybe, a dwarf? Does anyone know what a dwarf GSD puppy looks like.
If this is a GSD pup that is 7 weeks old, then it is a true runt, and looks like it has either suffered from serious malnutrition or has something seriously wrong with it. I wouldn't give 18.50 for the pup. Not to the owner. I think you are being lied to, or they were lied to. Either way, you are probably better off paying a proper amount for a dog, because this one will probably cost you more than that.
Still, it is a puppy, and it is alive, and it needs a loving home.
