I agree. Better to save up and get a better quality pup than run the risk of much higher costs (monetary & emotional) down the run. Nothing as a guarantee, but a little peace of mind is quite valuable. Also, if something does go wrong with a puppy from a reputable breeder, you won't feel alone. That's one of the great things about getting your puppy from a good breeder - they will be there to support and advise you for the life of the dog.
Dewey - I'm so glad that you were able to get out of that bad deal before you spent more money and got more attached. You poor thing. But it looks like you have found a good breeder now. You'd be surprised how fast you can save money for a corgi. And by the time you are ready, that breeder may have a pup for you. Definitely get on the waiting list. You never know when a fluffy or an undescended testicle will give you the corgi of your dreams! (just ask some of us here!)
PS - I feel that, given my recent "reputation" . . . I must advise you also to save up for toys and fancy collars and other doggie accessories!! I never realized what a nut I would be about buying stuff for my dog until I got one.
