Re- read Lorraine's post. She keeps track of the size of the pups in her litters. She knows the pedigree of her animals and what they have produced. Backyard breeders and puppy mill breeders have no idea about 3 or even 2 generations back. I would guess that Lorraine knows a very long history of her animals. As she said, she can give an educated guess but there is not guarantee. No reputable breeder would promise a particular weight. Watch the language they use. Genetics are tricky. Just because you have two parents that are the same or close to the same size does not mean that they will produce pups that are all close to that size. Those parents carry the genes of their ancestors. Sometimes something from way back pops into a litter. It becomes less likely with good line breeding but it cannot be completely eliminated. Line bred dogs need to occasionally have some new blood brought in and only someone very knowledgeable of that pedigree would have any idea which bloodline would be best to use in order to add the right mix. It's always an educated guess. |
