(As an aside, I see absolutely nothing wrong with pure-bred dogs. I'm curious to know what percentage of the people chastising the practice got their pets from a pound, or how much money they give to no-kill shelters.)
Simply put, there is little reason to keep breeding dogs (pure or mixed bred) given the outrageous surplus of dogs in shelters and those killed before they even make it to the shelter (most common practice - the dogs aren't even given an opportunity to find a home; they are brought in and euthanized immediately)
I got my current dog from the SCPA. And I gave $20 this year (I'm a poor student) to a no-kill cat shelter. I've volunteered my time since 1997 to both no-kill dog and cat adoption centers. So don't accuse me of being a hypocrite.
In fact, most people are hypocrites for being outraged over animal abuse (remember the threads here about Michael Vick) and yet indifferent towards the abuses that go on in pet breeding. As I said before, 3-4 million dogs are killed each year in the US due to overpopulation - and that doesn't even account for the physical abuse and deaths of dogs in puppy mills.
It is so easy to bring that number down considering the millions of homes each year that bring in a pet. Instead of going to a breeder or pet store, visit the county SPCA or a similar shelter. These dogs are very sweet. Some of them don't even have any problems. Sure, some of them are a little difficult at times, but they are sure easier than your typical teenager. It is also rewarding to save a dog from death.
But the bottom line though is this, my dog needs to get laid!!! I mean, he's 5 years old and the most action he's got is from a pillow. So any advices for the actual "love making" part of mating?
Yeah, get your dog neutered. It costs $50. And you kill two birds (the overpopulation and the horniness) with one stone.
