Great product! Highly recommend!
I purchased Ultra Mega Fish Oil Advantage to restore my dog’s coat, because he had an allergic reaction to something in our new area. The vitamin plus GNC’s oatmeal conditioner are working wonderfully!!

We used this product for awhile and bought it through Pet Smart. However, they didn't carry it anymore that's why we purchased it through you. We and our dog love the product.
Thanks for your service.

Even my hound has a nice coat!
I'm just switching my dog onto these from the liquid, and so far so good! It helps to puncture the little pill and squirt it over food, leaving the little capsule in the dish. It's pretty fishy once it's open!

My dogs like to bite into them and get the oil on the rug then proceed to lick it up.

love the product
I don't notice the fish smell on my dog as another review noted. I do notice a beautiful, soft coat. Even our groomer asked what I was giving our dog because her coat was so soft and nice. Love the product.
