You have been out of stock on Nutramax Denamarin for my small poodle for months! Are you planning on getting this any longer?
Answer by JustinaDec 16, 2021
It’s a supply issue. It is out of stock everywhere.

Are these tablets chewable or do they have to be swallowed
Answer by LolaGJan 14, 2023
This Denamarin supplement is in an easy-to-administer tablet form and is not chewable.

When do you think the Denamarin tablets in?

How long can my dog stay on denamarin?

This depends on the current condition of your dog. These tablets are safe for long term use. We recommend consulting a veterinarian for accurate feeding regimes based on your dog's health.

Frequent assistance

I have been using Chewy since my dog's 1st health problem arose. She is older so problems just keep coming, but she still acts like a puppy most of the time. The point is I have had to contact & change orders & autoship so many times, but every time the folks as Chewy are the nicest around, human always answers & never have to be on hold! It's a wonderful company & very responsive. I appreciate everyone & the help provided.

Happy dogs

Definitely 13 year old terrier has noticeably better liver test results. This product often seems to be unavailable....or back ordered for long periods of time. Otherwise I highly recommend it in either pill or chewables.

better than the chewables

We ordered this for our older Pug because he has had elevated liver enzymes ever since he was treated for Valley Fever. He never liked the chewable and we had to break them up and wrap the pieces in pill pocket. After a while it just got to be a struggle so we looked for something that he could just swallow and not have to taste. These were much better and he seems to have less GI upset.

My vet recommended the supplement as my pet has some liver issues due to being on phenobarbital for over 4 years. Hopefully, it will slow down the damage done & being done to his liver. Paws crossed!

Denamarin Liver Supplement

This product is extremely hard to find right now. It was priced fair, and shipped out quickly. I prefer the chewable tablets, but they are just not available at all right now. Hope they come with them soon.

Good medication

This has helped Ralphie heal his liver and improve digestion. His kidney disease has slowed and all is manageable with Ralphie having huge amounts of energy and enjoyment playing with his friends. It sure has made a difference in his feeling good and healing process.

Bring back the chewables!

My dog does not like these tablets. She is smaller and these pills are pretty big. Half the time she doesn't eat it even after I cut it into tiny pieces and put in pill pockets. Please bring back the chewable tablets!

Denamarin tablets

I'm very pleased with this product. After using Denamarin for only one month my dog's liver count went right to normal. I was really surprised and happy.

Need the Chewables

These pills are too hard. They spit them out and too big to give in a pill pocket. If my old dog crunches down on it, it'll break her teeth!
