Ralphie is a Boston mix with degenerative valve disease. He has been on this since he was 7 and he is now 15 1/2. Other people in the rescue I volunteer for say the same thing. It's a gamechanger when paired with prescription heart medication. It is also essential if you are going to feed a grain free diet. Awesome product!

I get these pills to sprinkle on my dog’s food. Sometimes, the powder is perfect. Others, the very first pill out of the bottle is gummy and impossible to get out of the capsule. Will be looking for an alternative.

Ok, this stuff is legit

Our Frenchie, Taco, has been on this for just under a month. The other day, I was FaceTiming with my mom, and she saw Taco and said, "WOW, his coat is so shiny!"

Our Frenchie, Taco, has been on this for just under a month. The other day, I was FaceTiming with my mom, and she saw Taco and said, "WOW, his coat is so shiny!" I had been noticing, too. The only thing we've done differently is add Vetriscience vitamins to his food. We open the capsule and mix it with a spoonful of wet food on his alkaline food. His vet recommended we purchase this because it is fish-free, and Taco is allergic to fish. Absolutely a win and highly recommend!

I love Chewy but these capsules were nearly impossible to open and remove. Occasionally I have this problem but not usually with my Chewy orders. There wasn’t a small pack”do not eat” packet inside this time so that’s probably why they were so sticky. My husband is upset with these capsules making feeding them twice a day to two dogs very maddening. If this happens again I will need to return them.

I was very excited to use this product after my cat was diagnosed with heart disease. Unfortunately, even with a silica packet in the bottle and keeping it in a cabinet, all of the capsules gummed up within a few weeks leaving the rest unusable. Don’t buy if you live somewhere with any humidity at all.

I need to open the capsule and mix it with food for my cat, but I was surprised to find the capsules are not fully filled. The powder is very sticky, clumps easily, and looks like it’s only about half full.

Much easier than the capsule

Franny refuses capsules. So a chewable works great and she loves them.
