It is really hard to understand the lack of communication to you by this breeder. I am so sorry for you, your family and Bailey. It is a shame that she seemed to find it no big deal to place your puppy in danger or other pets.
I hope that your vet supplies all the needed medical attention Bailey needs and he grows up to be strong and healthy.
Luckily not all breeders act like this...
Hugs to Bailey.
