I am so sorry to read this
Its hard enough worrying about a very sick puppy but with the added financial pressure on top it must be so distressing.
I really can only echo what others have said you must contact your breeder again when you get back from the vets and they have decided what treatment to give and how much its going to cost.
Although i dont think the breeder can be held responsible for the pups condition in my eyes she is definently responsible for covering any treatment needed.
Ant good breeder would bend over backwards to help in this situation IMHO
Take care, il be thinking of you and pepper
Posted same time as Francesca.
Every insurance policy on any animal i have taken out has only covered accidents for the first 14 days.
Illnesses have only been covered after the 14days as Francesca said.
