Nothing amazing - Coco has been on this product already. Product is the same I get from her vet. It is just easier to order on the computer rather than have to drive across town to get to the vet. It is also a little cheaper from Chewy and it was delivered very quickly.

The pill is huge

This is near impossible to give to a smaller dog, on an empty stomach. I am not sure how they expect you to feed this large of a pill without giving it to the pup

This is near impossible to give to a smaller dog, on an empty stomach. I am not sure how they expect you to feed this large of a pill without giving it to the pup without food...Wish I could return and try something else.

Unsure about product

The components of you meds and her prescription were different. I phoned our vet and explained this, he said it would be okay. She had her dose and became lethargic, and not her self. I had to carry her to potty. Took her to a vet in Illinois, she did bloodwork and a physical. Suggested we discontinue your meds and wait until we got home to our vet in Florida. We did and Toots was back to herself within 24 hours. This why I gave a three star. I’m not blaming Chewy. But it wasn’t an experience we want to repeat

My diabetic dog had a bout of pancreatitis causing his liver enzymes to elevate. This medicine was prescribed by his veterinarian & after being on it a few weeks his lab work improved. He took it easily in a pill pocket.

BAD TASTE

Cut the pill in half, hid it in a pill pocket and mixed it with her food. My dog - who is normally a voracious eater - refused to eat it because it tastes so bad

Cut the pill in half, hid it in a pill pocket and mixed it with her food. My dog - who is normally a voracious eater - refused to eat it because it tastes so bad. Would only eat her food when I removed this from her bowl so I just stopped giving it to her.

My pup is a bit older and lab shown replicated liver enzymes. MD recommended as treatment. So far her extreme thirst seems to be going back to normal. Have to order labs again in a month will verify then if she is better. I think this is a good treatment so far.

The best form to get into my pup!

I purchased the chewable form at the vet’s office but it was horrible getting it in her - she will eat anything except chewable Denamarin. This pill can be far more

The vet recommended this supplement for my dog when she was having poop issues. I give this to her once a day in the morning, an hour before her breakfast, and it has helped her so much! The price is cheaper on Chewy than anywhere else I’ve looked and shipping is super fast!
