I had 1 and only 1 accidental breeding and never bred anything before or after that... my nightmare dog broke out of his crate and scratched Cha-Cha's itch so to speak. And those puppies too by week 3-4 were already eating K-9 PuppyGold, Abady Granulated puppy formula and raw meats. Those pups were healthier than pups that I've seen at top breeders kennels. You could tell by their energy, bone structure, coat, the life they had in their eyes.
I know it's hard to take someone's word for it vs. a Vet or a Breeder and I don't blame anyone for being hesitant but if you do the research, I think you'll come to more or less the same conclusion that I did.
For the most part, the only people that feed better than I do are those that prepare fresh meals everyday for their dogs. I wish I had that time but I don't.
