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 JayCeeDec 16, 2021
It’s a supply issue. It is out of stock everywhere.

When do you think the Denamarin tablets in?

Can I cut the 500 mil be cut into to be 250. mil. You are out of the 250’s
Answer by LeeDJun 15, 2022
my vet told me I shouldn't cut the large dog pills in half...affects them somehow. So very aggravating to have to spend so much more for pills that are larger than I need for my 33lb dog.

How long can my dog stay on denamarin?
Answer by ChewyMay 09, 2018
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.

My Dog one of his liver numbers kept getting higher, No veterinarian knew why. Each vet kept saying as long as the other liver numbers are good not to worry. I was worried so my veterinarian said let’s try Nutramax denamarin so I agree. My dogs blood was tested after a few months and His liver count went from 3000 to 1100 It’s a start normal is 5-131 . I’m so happy and thankful to my veterinarian and the medication .

Cannot get dog to eat.

The product is fine, delivered promptly, but our dog absolutely refuses to eat them. No matter what we try, he either won't eat the food, or if we rap them in cheese, sandwich meat etc... he spits them out.

My vet put my 13 year old dog on this medication for her liver. A month ago it was not available- said mfc was out. Gave me a substitute that I could buy over the counter of which no one had heard of it. Thought I would try Chewy and what did I find? The prescription I needed. They certainly had it in stock. I try to deal locally but Chewy certainly has a new customer.

First time Chewy User and LOVED IT!

This script was on back order with my vet and they said to check on chewy as they didn’t know how long it would be. Went on chewy and was in stock and at my door in 3 days! First time Chewy user and now have it set up with auto ship. Very satisfied and will continue to use chewy for this and other meds also! As far as the product goes, it seems to be helping my dog with the liver enzyme control that she needed.

Denamarin and our “Oldster Boy Rookie”

Our almost 14 year old Sheltie boy Rookie has been having a few health issues for about a year now, one of which is liver support. Our doctor advised us to start Denamarin. Rookie has done wonderful on it and is still with us today, which we did not expect. It has become hard to get at times though, but Chewy has been a reliable place to go to find it. Thank you Chewy! For many other reasons, you are an UPSTANDING company and we highly recommend you!

So thankful

My little guy has to take this every day. It got to the place where my vet was always out of it or they couldn’t get supplies in I worried if he would miss days taking it. So I checked with Chewie they had the exact same thing and it was much cheaper than what I was getting it for. So I set up for automatic shipping peace of mind hopefully they won’t have trouble getting it in the future. Thanks Cherie for always being there so pleasant to talk to if I have questions and delivery is most times next day.

Why I ordered from Chewy.

The only reason i ordered from chewy is cause this product was on back order at the vet. Chewy is more expensive & have to pay tax. I am on a fix income so have to get where I can get my pet meds cheapest & have same product .

Denamarin Tablets

My vet recommended denamarin for my pup. These are pills that cannot be crushed or split and have to be taken on empty stomach so no hiding in a treat. I will have to shove down my dogs throat to get her to take it. I will be looking at other chewable options when we finish up the order so we’ll both be happier. I am hopeful these will help her liver though.

Denamarin Tablets

Too early to tell if the bloodwork problem is satisfied, but for the first few days the dog was lethargic and inactive. He is more active now after ten days. The proof will be in about 15 days when he has bloodwork done.
