Do you have other dogs in the house? That would certainly be a factor in bringing an un-vaccinated dog in to the picture (both for it's protection and your other pets~worms!). There's lots of discussion on this board about when to start vaccines. Lots of controversy among the vets, too. Mine starts at 6 weeks, then 9, 12 and 16. I know not everyone here agrees with that.
There's just so much socialization that goes on during those first 12 weeks with mom. But a good breeder is also socializing the dog to people during that time. It sounds like the puppies are all missing that aspect if they are being stuck outside.
It's just sad, no matter how you look at it. |
