    Great pills

    By Cagney on Oct 14, 2020

    My Westie would lose hair on her back end every time she came into season, or was pregnant decided to try this vitamin supplement since she was already eating the best food. Worked like a charm no more hair loss. I use the spray cheese on the pill every day and she just gobbles it up.

    Must taste awful

    By Luna on Mar 15, 2020

    I don't know if they help her because it's a process to get her to take it. It's too big to make her swallow whole so I gotta crush it up, which makes a mess. Then I try her go-to treat, cheese, and she still won't take it. I tried sprinkling on her food but then she's reluctant to eat. Not good if she's pregnant. $37 down the drain

    Great vitamins but.....

    By Kris on Jan 6, 2020

    My dog will not eat these willingly so I tried crushing them. Vitamins are so hard and very difficult to break up.

    My dog loves them.

    By KTSfinesse on Jul 26, 2019

    My very finicky standard poodle female, love these. She is pregnant and I just started using them so I can't speak for the results on litter size or health benefits yet. I tried revivals oxy momma with a previous litter and got great results but the price for the amount I need for my large breed is very expensive. Hopefully these work just as good.

    She hates the taste but they work

    By Brikkibrat on Jul 3, 2019

    My breeding female is getting up there in age and we wanted to try to breed her one last time so we ordered these to see if we could get her to where she needed to be to have another litter. After about 2 weeks she was acting more like a puppy again and finally started coming back in season. She was already 2 months late. She will not willingly take these! She hates the taste and will not touch them BUT they do work so if you don't mind making your pet take them, I would highly recommend them!!

    Prenatal Pills

    By PakRat on Jun 20, 2018

    My female miniature schnauzer isn't to fond of the taste of these pills and they are a rather large size for her to chew. Would be a little hard for a smaller dog or cat to chew easily. I break them up and offer them with peanut butter. Will look for another prenatal pill next time.

    No Way Mom

    By Abylady on Aug 9, 2018

    My queen won't even stay close when I open the bottle let alone eat them. I broke them up and tried putting them in food but no luck.

    breeding female vitamin

    By vitamins on Jun 23, 2018

    I have several breeding females and only two liked the taste. They have a smell and my dogs wouldn't even touch them or would split it out immediately. I even broke them in half, no success.
