    Great Product by Katie may from Scottsville, Ky05/12/2013

    My dog will have to take this product all of her life. It been a life saver for her.

    Good Results by Shelsbells from Los Angeles, CA06/11/2013

    I purchased this product on the recommendation of our vet. Our 13 year old dog was diagnosed with advanced liver cancer in early March 2013. We were told there was really nothing we could do other than try to keep her weight up and make her comfortable. The vet suggested Denamarin to improve her liver function. Within days we noticed positive results. Our dog has a little more energy, is more interested in eating and her digestive issues have subsided. Not sure how long she will last, but this product has made a difference in the quality of her life. The coating on the pill makes it extremely easy to administer.

    Brought Alk Phos down to near normal in 2-3 months by nvc from North Carolina09/12/2014

    Our 7 year old Rottweiler never seemed to recover from a severe bout of pancreatitis a couple of years ago. His liver enzymes remained elevated, despite no sign of tumor or cushing's syndrome. We put him on Denamarin and his values improved, so we took him off (since vet had originally suggested a 6 month course). Next thing we knew, his values were back up. AST and ALT were not bad, but Alk Phos was first 400, then 850 a few months later (normal high is around 250). After being back on Denamarin and a new Prescription hepatic diet for about 2-3 months, his Alk Phos is now down to about 286, still a little bit above normal, but what a drastic improvement from 850! Maybe it will go completely back to normal with a little more time. Not sure if it is the supplement or the food or the combination, but it was definitely the supplements that worked the first round since we didn't have him on special food then, so I believe that the med was at least half or mostly responsible for the improvement the second round. I am not willing to take him the off the hepatic food to know for sure, though. Despite the cost, we plan to keep him on both permanently to avoid a relapse.

    This stuff works! by pat from Champlin, MN03/20/2013

    Our 3-year-old golden retriever had elevated liver enzymes. Our vet suggested Denamarin and after being on it for a couple of months it's almost in the normal range! Hopefully this will keep his liver healthy.

    great liver supplement by oliverandbear from Richmond, Va05/25/2013

    This product was recommended by the vet after my dog had gallbladder surgery. He had been running a high liver value for some time. He has been on this supplement for over a year now and while his liver value is still not in a normal range, it has come down to the lowest level he has ever had. I really think this supplement has helped him so much. This has to be given an hour before eating breakfast.

    Saving Dog's Life by MAM05/31/2013

    ER doc recommended this for severe jaundice. It helped!

    Health and Energy Enhancement by Dianne from new york, ny12/05/2013

    Our 9 year old lab and golden retriever mix is showing improved well-being, overall better health, and higher energy level with Denamarin (for large dogs) taken once per day. This supplement is a liver protectorant and seems to be making her feel more vital with no side effects. She has an atypical cushings disease condition and this supplement really seems to help her functioning despite this problem.

    Called before I ordered and they said the product was in stock, received 30 pieces of 220. Call to tell them, they said will send remainder next day. 9 days later, nothing, called again, was told on back order...canceled order, horrible customer service, will not buy again from them.

    I tried 1800pet meds and was not satisfied with them. Entirely pets is such a better on line service. Thank you for all your help.

    Did not get to use as unfortuntally my dog passed away before it arrived.

    DENAMARIN by DIANE from Glen Mills, PA08/27/2013

    Received product very quickly, within two days. My dog must stay on this medication for the rest of her life as she has cooper on the liver. We have had difficulty purchasing this product but Entirely Pets has made this a simple and quick procedure for me and "Casey" Thank you. Also price is much cheaper that purchasing for vet.

    Was not happy with service by KCY06/10/2013

    I ordered this product from the on-line store. Never once was it mentioned during the ordering process that this product was out of stock. Hours later I received an E-mail saying that the company no longer sold prescription medicine....this product is not a prescription so I called the company to see what the problem was. I was told that the product was on back order and they would have it with-in 10 days. When asked if they could guarantee the 10 days they said no and added it could be up to 6 weeks before they might have it. I had to cancel the order and order the product through another company. The company should not allow orders to be processed without informing the buyer that the item is out of stock.

    Denamarin is helping, probably by D in Philly from Philadelphia, PA10/09/2013

    My 103 lb boxer is taking Denamarin to help with his liver values after going through chemo and radiation for lymphoma. He is in remission since April and has been on Denamarin since then as well. While his values are not back to normal just yet, they are trending in the right direction. I'm not positive it is the Denamarin, but the pills are not hurting and I'm not going to stop giving them, just in case they are helping his liver.

    Denamarin for Large Dogs by Judy from Virginia08/29/2014

    I have a 13 yr old Basset Liver problems. Vet suggested that she go on this to boost liver function. Blood work before and after shows that this is working. No side effects seen.

    Helped my dog tremendously by shelter volunteer from MD11/14/2013

    My aging dog developed liver failure. One of his symptoms was vomiting a yellow bile foamy substance (frequently). The Denamarin has all but stopped that, so hopeful that it is helping.

    Best product for healthy liver supplement by Play07/03/2013

    Vet recommended Denamarin for my dog with a liver shunt. It doesn't get more praise when your vet puts your dog on a product. Had the operation, and will continue to give her this, so her liver will continue to be healthy. Best price online is at Entirely Pets!!!

    Great product by Sandief01/01/2013
