Welcome to YT! Wow - you have been thru a lot with this little girl? How is Ayla doing now?
It sounds like the breeder was just awful - very irresponsible, sent you a very sick dog. Have you contacted the breeder? They should be paying all these vet bills!
I'm not sure what to tell you about the shot series. It's been a long time since I had a new puppy & there are new recommendations. My vet is very, very conservative - a holistic vet who believes many animals are over vaccinated.
Maybe a breeder can give you better advice.
Glad to here that YT has become your 2nd best friend!
This is really a great place to learn & we have a lot of fun her too!
