According to your own website, you list "two" of your breeding stock (females) with weights just tipping the scale at 4 lbs...Daisy - 4.35 lbs, Zoey 4.25 lbs. You do have other females within recommended weights for breeding...Ava - 6 lbs. & Chloe -5 lbs. Maisy another female does not have a listed weight...?
I am not "assuming" anything about you. I am making my own judgment based off your own admissions from your website. Those are a concern to me and being an animal advocate, I am more worried for your females vs. your feelings.
Just because you have been breeding for seven years and have only had one close call does not make your breeding practice correct or to standard.
I am however sorry if I hurt your feelings...truly I am.
