OMGoodness, how very tragic for you. I am so sorry for your loss.
I have no advise on what you can do at this point, it's not like the puppy dies 2 weeks after getting her the breeder can say the dog was in your care, they don't know what you subjected the puppy to. I never heard of a breeder giving puppies shots for kennel cough.

I would be pointing my finger at the vet. I would think there are meds that could be given to a 4 moth old pup for what the vet thought was kennel cough.

I also would not use this vet again. We have to have faith and trust in our veterinarians after all, they are our babies doctor.
Hopefully other member can offer up some advise or suggestions for you.
