Purebred Breeders Purebred Breeders sold me a sick dog and won't honor guarantee Florida

We adopted a french bulldog puppy thru Purebred Breeders who we had to put down before he was age two.  He was diagnosed with all kinds of congenital abnormalities when he was a year and four months which resulted in us putting him down.  When we informed the actual breeder, Iron Head Run, they wouldn't even respond to us.  We also tried to adopt his sister from a different litter, but same parents, but she ended up having heart disease. 

Thank God we found out before she was shipped to us.  Now that we are trying to get this resolved through Purebred Breeders they are being difficult to deal with and non responsive.  We have documents from our local Vet as well as the Mass Vet Hospital where he spent a good deal of his last 6 months of life.  Do not purchase a dog from purebred breeders, save yourself the heartache.  And definitely do not buy a puppy from Iron Head Run located in Oklahoma.
