If you got her from a breeder and they have said this I am sorry. Trying not to sound mean but that was not breeder that are to be there for life in good and bad.
I would find her a good loving and happy family were she can be a puppy and enjoy her life. This may sound mean but you need to do what is correct and right for the puppy. All my animals cat, dog, bird are my children just as my two legged children we are all family.
I hope you can find it in your heart to do the loving thing.
