Windhaven Kennel/Companion Puppies Hesperia review: sick dog

Got a puppy on Saturday 1/6/18. On Tuesday 1/9/18 the vet found it had Giardia. Needed to be hospitalized overnight because he was so sick on Wednesday 1/10/18. The Vet bill was $1, 600. Breeder said it was because the dog was stressed. This breeder put my family and other pets at risk. Giardia is not something that you can eradicate easily. This Breeder has a problem at her kennel. She also boards dogs. She breeds Bernese Mountain Dogs, German Shepherds, and Corgis. Buyers beware. You will pay top dollar for the dogs and may have a potentially very sick dog!
My kids were traumatized as well! Very sad situation.
I believe the breeder should pay this vet bill in good faith.
