I'm not sure where to buy a yorkie in Houston, but you might want to check ads in the paper and make sure you can see the parents and that the puppy is not from a mill. I've spent thousands of dollars on my FancyPups pup due to medical problems. I highly recommend that you do not buy from them and you get your deposit back however, if you must buy from them have a vet set up right after you buy it and have blood work done immediately to make sure it doesn't have liver issues. My dog also had leg issues, so have them check the legs too. I didn't find out that my dog had medical issues until I had blood work done which was too late. I think they only give you a day or so for check ups. Unless you want to spend thousands on medical, have blood work done asap and be prepared to return the pup or find a reputable breeder and make sure you meet the puppies parents and check their medical records. No puppy parents= puppy mill or puppy broker. Good luck! Hope you find a healthy happy pup
