Yes Puppies N Love knew that my puppy had Giardia because they were treating her for it and she had been previously treated, so twice and they sold her anyway prior to testing her fecal sample on her fifth day. They allowed me to socialize with her and play with her even though she was being treated for this. This is a bold face lie from the corporate office. Oh and by the way Giardia is not a casual illness. My puppy is failing to absorb her food and is still thin. she can have life long issues from Giardia such as IBS (irritable bowel syndrome) as well a digestive issues because now she will be on round four. I scrub my floors and kennel constantly, give her a bath or two every day, smell poop constantly in my home because she is not absorbing her food - this is no easy illness. She is kenneled at night and when I am not home for her safety she has to be in the kennel from time to time and at night so she doesn't get into something that she shouldn't. Because she is so sweet and my Sebastian loves her I can't possible take her back or I would. trust me when I say this ruined my Christmas, I can't play with her like any other puppy. Try cleaning up fecal matter from the night. The CBC states it is very easily transferred to humans. The CBC doesn't take this lightly and either should you. Something is wrong with Puppies N Love and their Kennels. I do not mind the Kennel Cough and my other dog has it because the Vet said she was fine. Their vet doesn't know how to read the shot record any better than I do - now that is saying that they are trying to hide things. Bold face Liars.
