I would not recommend feeding any artificial sweeteners to dogs or puppies. Even artificial sweeteners that are considered to be "all natural" can cause serious side affects to dogs and especially puppies. Why not give the wormer in some canned dog food, that would be safe and the dogs and puppies will enjoy it. Happy New Year!
reduces fertility Re: Stevia safety in puppies and dogs
According to the catalog of NJ's Well Sweep Herb Farm, which sells Stevia, it reduces fertility. I would not use it for potentially breeding dogs--or people--without further investigation. I found it in the paragraph about Stevia plants one can order.
