My vet recommended these for me to get got my newf after she whelped her pups. I couldn't find them at any pet store and was getting nervous as her due date was quickly approaching. I did a quick Google search and found them here on entirely pets. When o received them I was a little worried she may not take them. They are fairly large and she being 120 lbs. had take 11 of them. To my relief she loves them. She thinks they're treats. She loves them so much I cannot leave them on the counter because she tries to snag them. Thank you for helping her and her pups stay healthy during the nursing stage.
