Dusseau's Perfect Pups

We purchased a puppy from Dusseau's perfect pups and have had nothing but problems with our puppy. He came with a pot belly full of worms. We could not believe how many worms he came with. I never received anything regarding a heath guarantee, although it stated she had one on the ad and her website. Never got a contract either which was odd because most people care where the puppies go. Our puppy has a horrible immune system and bad allergies. We have spent hundreds on vet bills and our vet couldn't believe the problems he has faced. He just got cherry eye and has to have surgery. The vet also found parasites on him. We tested our other dog to make sure it did not come from us and she was healthy on everything. We also took him to a dermatologist and she saw how bad his allergies are. The mother is beige and on akc it states she is brown and white. I have talked with multiple breeders and beige Newfoundlands are known to have health issues. We love our puppy but are nervous to what the future holds for our poor teddy.
