Why would it surprise them that you got a puppy?
Now if I got a puppy that would surprise EVERY one. I don't do puppies!
Did you get a well bred dog or one from a BYBer or Puppy Mill? There are warnings out about buying from either one of them.

If you have not got your puppy yet, please heed these warnings. Both are liars, scammers & will screw you just for the money. Selling sick & deformed pups, genetics are all screwed up. They do not genetic testing or use selective breeding tactics. They are breeding for money & are doing nothing to better the breed, in fact they ruin many breeds.
Be ware of who you buy from, get pup checked out by a Vet, get a wellness exam & get the pup started on its puppy shots. If the pup is younger than 8 weeks of age, you bought from a BYBer or Puppy Mill.
