1. If some one wants something they will pay for it, often people seek out the unusual, they may not keep it or treat it properly but the same goes for pure bred dogs, people buy a dog and not always realise what they are going to end up with. Like anything, the cost depends on supply and demand.
2. Breeders have thier different reasons, some JUST for the money, some because the want to say they have created a wonderful animal by thier choosing and some, for the fun.. the idea that tests to show how fast, attractive or aglile they are is silly, a lot of people JUST want pets, any other owners will seek out dogs with certificates, it so reminds me of taking children to beauty pagents. Health checks are a different matter and I agree with them, well most of the time.
3 How many people on here have hobbies? or drink? or eat too much food? know one adds up that cost as you only get pleasure out of it, so thats my view, for some its a nice hobby, you have a nice dog and have nice pups and sell them to some one else who also wants a nice dog...a bit of money for doing it is a bonus, not a champ anything!!!!!!!!!!
