    Zentonil - saved my dog's life
    February 25, 2015
    My dog has been taking Zentonil as recommended by vet for four years now. It has saved him and his damaged liver. Our vet now says he doesn't show any signs of a dog with liver damage.

    Zentonil Plus Good Purchase
    February 9, 2015
    Our vet put our little dog on Zentonil Plus awhile back because of liver problems. Have been giving them to her since then and find I can order them on line here. Have them delivered within a few days at a very good price. Also have specials like percent off or free shipping.

    I received exactly what I ordered.
    Just too bad shipping to Canada is not free on orders over $90. With the dollar exchange and shipping, it added up quite a lot. But the product is exactly the same as from my Vet.

    I bought the Zentonil Plus through Amazon and Entirely Pets. The medicine works great., it arrived quickly and was cheaper than going through the Vet's office directly.

    I couldn't believe how fast I got my order. It was within a day or two after I ordered and that was ordering ground shipping. Very happy with entirelypets service and products.

    As far as the product itself I can't say whether or not I would recommend it as this was a vitamin prescribed by my Vet.
    I can only really judge its price and the efficiency of the order process...which was great...lowest price I found...easy ordering...and fast delivery!

    Zentonil Plus 400 mg
    June 12, 2014
    I was skeptical about giving our dog who has pancreatitis at first .Our vet recommended this product but was too expensive to use on a full time basis .Checked on line with Entirelypets and read the customer reviews about this product .We bought 2 months supply and hoped for the best .Within 2 weeks we noticed a big difference with our dog , she was more alert , active , and looked more alive . The big test was the next week when we took her to the vet for urine and blood work . The first thing that the vet said to us was that this was a new dog .Something was different about her , she was on a few different medications over the last few previous months and had not improved . The vet did the 2 tests and to our amazement , there were big improvements with the results .The urine came back clean and at 100% and the blood work had also progressed to positive territory . I don't understand all the results in vet terms , but the vet said that it was a hug change for the best .So seeing is believing . My wife and I are very happy with the results .Our dog is aging and probably doesn't have many more years left , but if we had not have used this product I not sure how much longer our dog would have lasted with her pre-existing condition , we had tried all means prescribed by the vet until using this product .So bottom line is that we are sold on Zentonil Plus 400 mg .Thanks John + Janet Clifton.

    Zentonil Supplement
    May 10, 2014
    This product has helped keep Hoagie's liver enzymes down. We found out she had elevated enzymes when we took her in for dental surgery. We had to wait until the levels came down. The vet's price is about twice as much as Entirely Pets price! If we need to purchase any other supplements, we will definitely look at Entirely Pets to purchase them!

    Life Saving for our Dog
    December 27, 2013
    We have a 10 year old boxer who has been very active, but just over a year ago, she seemed to be on her way to heaven, after taking her to the vet and having some blood work done, he put her on this liver supplement, and ever since we have had a second chance with our girl! It works fantastic!

    great suplement
    August 23, 2013
    I am happy with the results! Midnight has spent a life time on drugs (very bad for her liver) but apparently they helped with her seizures. I've reduced those drugs dramatically and added this product. It seems to provide more energy, awareness and enthusiam! Her seizures have not dramatically increased although I have reduced her meds by 2/3 with very little repercussion to our sweet girl!

    I'm so glad I found Entirely Pets!! I was paying double at the vet's office for the Zentonil Plus! The service is excellent, and I receive product within 5 days or less. I would definitely recommend to others. Thanks!

    My vet prescribed this for my 9 yr old Jack Russell terrier who's been suffering from possible liver cancer. It has really increased his quality of life. I found it at for just about half. Since I will have to give this to my JR for the rest of his life, saving that much really helps.

    June 20, 2013
    Fabulous results with this product. My vet wanted my dog on it because his liver enzymes were high.
    Worked very well. His liver enzymes are in the normal zone now. Would never do without it.
    I buy it from Entirely Pets because it is too expensive at my vet. Good service and good delivery time even to Canada.

    Dr. Prescribed this medication saying it was a life time medication needed for my Boston terrier. Bought it the first time from her and knew I had to find the medicine at a more affordable price. That's when I found Entirely Pets. I have been buying it for over a year now the price has remained the same. I send my order in and it is at my front door within 2 days. Wonderful service.

    My almost 13 year old dog was diagnosed with liver cancer and the vet told us that Zenitol would help him. The cost from the vet was over $150 for a 2 week supply. Although you really can't put a price on your dog, reality must remain.
    I found entirely pets online and the medication less than 1/2 price and it shippped all the way to Canada in less than 10 days, i was thrilled.
    The best thing is, my dog feels fantastic. The difference it has made is phenominal, he's like a puppy!
    By christina
    very affordable

    August 16, 2012
    This product has turned my dog around. He has liver issues and now after being on this medication long term - he is back to his normal self. I am anxious to have his blood taken again to check his enzymes. From his behaviour and state of health now I am sure the enzymes will be down. Great product!!
