Best probiotic I've tried
I've tried a few of the "top" sellers but this was the only one that made a noticebale difference (Especially at the 2-3 month mark). His digestion has been so much better and the pep in the step is back.

Effective supplement
Honestly, we didn’t expect this to work, no more pacing at night, reacting to noises, or any anxious behaviour. Definitely staying in our daily routine.

Support for older dogs
I subscribed to the bundle with 3 supplements monthly and wow. There is a reason they have an industry leading 8 certifications.

Less Vet Visits
The probiotic and other ingredients have really made our little girl happier, we have saved so much on pet visitis since starting this months ago.

Would recommend
My vet suggested the Hip and Joint supplement when my 2 boys started showing signs of Althiritis (apparently 80% of dogs get it?), after 2 months and another vet check up it seems to have worked wonders!
