A champion bloodline is when the puppy's mother and father are from show kennel stock (A specialist breeder who has bred a certain breed for several generations and have dogs that have won at the highest level) and usually involve most dogs in the breedline being champion show dogs in the UK that involves having 3 Kennel club challenge certificates, which are obtained at championship shows if the dog wins it's class and is placed amoungst the best of breed. Champion sired is when the puppys father is a champion show dog in his own right. The health certificates are obtained from the vets when you have your dogs eyes, heart, and in larger breeds hip scores checked.
The current prices for Chihuahua's are rediculous mainily due to a lot of celebrity chihuahua's. Most show dogs are fawn, cream, red, sable or black and tan. Just because the dog is expensive doesn't make it well bred I recommend you contact some breeders and attend some chihuahua shows to decide what type of chi you want. BTW only the apple-headed chihuahua's are show quality and fit the show standard the deer headed sadly dont due to not having the correct apple-domed head, this doesn't make them any different as a pet though.
