It is better so spend a little more now on a pup. Then finding a cheap pup and having to pay a mountain of vet bills. Save up and go through a reputable breeder. The YTCA website is a great place to start. Check out my blog to find a list of questions to ask them. If they can't answer them ,then go to another. Save yourself heartache by getting a healthy pup. You won't regret it !
