Hey Michelle. Welcome. I say stop worrying and enjoy that little Freddie. The more knowledge you gain from boards such as this will allow you to know better if and when you purchase another cavalier but sometimes even though you have done your research and purchased from the best breeder you can find you can still end up with a dog with a health issue. The difference being though the breeder will be there to help you through it. Freddy may or may not develop problems..you can't change that but it sounds like you do know now that a pet shop is not the best place to purchase a pup. Seems Freddie was meant to be in your life no matter what Love and enjoy that Freddie and please post some pictures so we can see the little guy.
