Good but deliver An issue accepted delay due to weather but DPD said I changed day of delivery when I did not


excellent value 1234567890


Great price (half the price from the price my vet charged) very speedy delivery.


Would be paying twice as much for theses tablets at the vets


recommended by our vet and till next blood test won't know whether it's helping liver function


The work and the dog is feeling better - I think


Great product at a great price


This is an amazing product. Our elderly dog was diagnosed with a liver tumour and Zentonil has given him a new lease of life. He's back to how he was 12 months ago. The only reason that I have deducted one star is because there must be either a nasty smell or taste to the tablet. At first, we were able to administer it wrapped in pate but now he sniffs the pate thoroughly, then refuses it. Next, we tried crushing it into his evening meal but he has also started to refuse that and will only eat it after an hour or so when, presumably, he has become extremely hungry. Even adding fresh meat juices from our own food - normally a sure fire way for him to wolf his food down - will not tempt him.


My dog has minor liver problems. This product was recommended by vet.


Easy to order and half the price my Vet charged me, and arrived promptly.
