Review your contract for any health guarantees right away and make sure that your new baby is looked over right away - so many times people don't do that right away and by the time they find and issues - they are so bonded or their opportunity to return or have the dog replaced is gone.
I always recommend that if you are purchasing a puppy from a different state - or for your own for that matter - make sure you know what the Puppy Lemon Law is. Better to have all this upfront than to scramble to find it later.
I would say find a Vet Opthamologist and have eyes checked, get a fecal sample and draw blood (which you will send in to OFFA to check for fanconi) You will also want to talk to your vet about HA how it's tested for and at what age.
40 years ago - reputable breeders essentially erradicated HA by testing and not breeding carriers, animals that were in commercial or high volumn kennels were typically not tested and in those lines we still see HA along with some malabsorbtion issues.
Oops - didn't mean to sound so negative - just hoping that you will do some legwork up front so that you are prepared for things that hopefully you will never need.
