A friend of mine, I am now learning, without a doubt is a BYB. It's purely about making a few bucks, and she just owns two of the same breed of dog, they mate every time the female comes into heat, etc. They also live out in the country, so no fence, and other dogs come calling when she is in heat too. There is currently a litter of 14! 9 that look full blood and 5 that look mixed. So my first question is, can that be? Can there be 9 full blood and 5 mixed? How do you know for sure that some that look full blood might not be mixed too? The worst part is that my friend moved the pups outside because "the weather is nice" and now the momma dog is confused and has been taking some of the pups elsewhere and they are constantly having to move the pups back. Because of this they are wanting to get sell some of them at only 4 weeks old! I told her that in some states it is illegal to sell a pup under the age of 8 weeks and she was like, oh that's just toy breeds....she won't listen! I need some hard core facts (like university studies, Dr's studies, etc) about why not to take them from the litter that young. I couldn't find anything on the net. This is such a mess....I am going to try and talk her into spaying her female dog after this. Please help!
