I got a dog from akc breeder and had to put her down 2 weeks later as she was sick. Breeder said she had clean bill of health. Do I have a case.

The vet said she was around 2 weeks old when she got sick. When we picked up the puppy at 7 weeks old she was covered in feces. The breeder said he wont give us the money for her or the vet bills as he did not guarantee she would not die. But he had lied and said he had wormed her and taken her to a vet and she was healthy. She had Giardia, parvo, roundworms, and 3 other intestinal parasites.
