It has made a real difference
Saffy has a very sensitive digestion and gets upset tummy a lot. Until we started giving her these. They have made a huge difference and she rarely has any issues. She loves them too, as much as any of her favourite treats!

Amazing Product !!
My girls love these. The moment they arrived my girls were so excited to try. They love the smell and ate one the second they were offered. These have helped one of my girls with her itchy paws and now she no longer licks them. They are most definitely value for money as nothing so far had helped my girl and taking these twice she instantly stopped licking. They come in a handy pot that keeps them fresh. These are highly digestible and have improved both of my girls number 2’s making them more solid. I wish I had found these sooner as it would have saved me hundreds in vet bills. I highly recommend them and most definitely will be buying more.

brilliant pre/probiotics
We have a very fussy poodle who was scratching and chewing her paws all the time.
Since starting her on Omni pre/probiotic supplements each day she is so so much better.
She is even eating her meals much better too.
Thank you so much.

Great solid poops!
There were occassions where our dog has sloppy poops or chewed his feet. Not sure if its a placebo effect, but the Pre/Pro biotics seem to have helped with those issues. He'll stay on them until we see otherwise.
