I am very satisfied with this product. We found out one of my dogs has a tiny liver and it was working overtime to process his food. These pills help his liver function and now he eats every meal.

My 14 1/2-year-old miniature schnauzer has been on this medication for the last 10 years. I attribute her long life to this medication. It's been tough to find lately, but EntirelyPets has had it and at a competitive price. Thanks!

Phenomenal product
June 8, 2021
My 15 YO pekingese had become lethargic and did not have much interest in eating. Blood work showed liver enzyme were elevated. I began giving her this product and within 3 days she was dramatically improved. Her energy was amazing!!!!! She tootled around the house like she was a puppy. Her appetite returned to voracious levels. Her liver enzymes returned to normal. We continued to give this to her long term.
  • Rapidly effective. Easy to give in small dab of cheese.
  • Must wait 1 hour after giving product before dog can eat.......poor baby!

Supports healthy liver!
September 26, 2020
I have been using this product for years on various pets with liver disease. My most recent is a 14 year old minature toy fox terrier that was diagnosed with hepatic carcinoma in 2018. She underwent chemo and radiation and has been in remission since mid 2019. I started her on Denamarin on the advise of her oncologist and her liver values have been very stable since her remission date. I now give this to some of my other senior fur babies to help boost their aging liver issues.

It appears that it is helping my Gordon Setter Liver function. Good product.

Merchant Response:We feel the same way about your pros and cons. Wish it wasn't so expensive, but it's a difficult substance to produce. It oxidizes rapidly once exposed to oxygen. Great care is taken during manufacturing including doubling the active amount as well as entracoting and blister packing. Take care GBG!
  • Reasonably priced for this med/
  • Still a bit pricy

Dog Liver Function Decline
April 10, 2020
My Hannah's liver (she is 12) started declining in function last year (Please do a complete blood panel on your pups every year!). My Vet recommended Denamarin as the first course of treatment. It really helped improve her enzyme numbers. Now she is also on an additional med and we have stabilized or really slowed the decline of her liver function. She is active, happy and eating well.
An expensive product but liver blood screens showed it to be very effective in my case.

Merchant Response:Beautiful Denamarin testimonial Kenton. Be well
  • Effective in my dog's case.
  • Expensive.
