I have not heard of any possible problems with fertility with legumes in dogs. Human males sometimes get concerned with very high levels of soy, but that should not be a problem in female dogs. There was a study with very high levels of flax seeds in dogs which can be moderately anti-estrogenic which could potentially be an issue in female, but that should not be an issue with normal dosing.
I hope that was helpful and answered your question. Thanks for using Petco Pet Education Center, formerly Petcoach.
