I am so sorry you ended up with a sick puppy.. but please do not beat yourself up anymore... love him, take care of him.. sounds like he is lucky you have him...
Many times people are taken by breeders also.. so it is not just a pet store.. I have had yorkies for many many years... I am on my second complete family.. and have 4 now.. I wish I had found YT prior to my last purchase and one I ended up letting my daughter have that was so aggressive..
So as you will see, it is not always pet shops that sell sick puppies, there are many many scammers out there..
puppy hugs to you and your baby...
