Here's what may happen if you don't take a puppy...
A) You don't take a puppy. Another person easily steps in and takes the puppy, mostly due to the cuteness factor, and with little planning, but hey. That happens. But so long as we can even just DECREASE the number, that is a start. If you don't get this puppy, there may be room in your heart and life for a dog truly in need, who wasn't bred for commodity's sake.
B) You don't get this puppy, and no other buyer steps forward. She keeps the dog. She may breed it, or she may neuter it, but either way the rejection and being forced to keep the dog may give her the kick in the @$$ to realize that there is a shortage of homes. If she breeds it, a harder kick in the @$$ will come when she can no longer afford, or find homes for what she has done.
C) You don't get a puppy, and no other buyer comes forward. She decides not to keep it and brings it to a shelter. There, you can pray some good, kind person will give it a forever home. She may get some well earned strife from the shelter workers, she may be told that there is an overflow and the puppy will be put to sleep. The puppy deserves none of this, but it was put upon it by her irresponsibility.
I don't know where you live, but in the US, only 19% of 77.5 million pet dogs were adopted from shelters. Roughly 3-4 million dogs and cats are put to sleep each year in shelters.
Bottom line: For every puppy this woman breeds, there is one less family who is going to rescue a shelter dog or go to a responsible breeder.
And if you are going to talk the talk, walk the walk too. I'm a vegan and my uncle is a butcher, I don't buy his meat because he's giving me a great deal on it, or because I'm entitled to it from before I went vegan. That would be weird, right? Hypocritical. If you are against animal suffering and over-population, why turn around and fund it?
I hope this didn't sound too harsh, I meant for it be more informational than angry.
