They are keeping my dogs liver function under control


Denamarin has saved my dog's life. He was very ill with ongoing liver disease but will now be on this product for the rest of his life.


Excellent service, worked a treat


This product was recommended by the vet and found that it worked with quick results


What the vet prescribed, but saved more than £50 (after taking off the private prescription fee).


We will be ordering a second batch shortly, we are not yet sure of their efficacy since our dog is on a four month trial and his blood test results do not yet show an improvement in his Liver count.

We will certainly return to provide a further update in three months or so.

My rating of five stars relates to the service provided by Pet drugs online. The particular drug was indicated by our own Vet.


They seem to do what they promise?


Great purchase and super fast delivery


was recommended by our vet and seems to improve the health of our dog


They've done wonders for my dog's liver problem
