Thanks! Yes, both breeders were reputable (not BYBs) and pups came with AKC registration and papers and with full health checks, guarantees and vet checks. My husband had been a dog trainer and has plenty of experience with a wide range of dog breeds. We have had a lot of different types of dogs throughout our lifetimes and we find most often the "standard" doesn't always apply. Each situation is unique.I wish you good luck in raising these puppies. You may also want to do a google search on "litter mate syndrome". You need to raise these puppies separately so that they can be independent. I have to suspect the quality of "breeders" that you bought these puppies from. No ethical breeder that does all the health testing (hips, elbows, eyes, heart, NLC,etc) and shows or does anything with their breeding dogs would sell you a puppy and another of the same sex....when you had already got a puppy. Most likely BYB's that will sell to anyone with the money. I would make sure to get pet insurance on these pups, and be prepared to be able to crate and rotate in another year to 18 months.
