I wish I had just gotten a good fish oil for humans that is more refined and no odor. Our vet wanted Frosty on 3V Snip Tip "HP" caps. The HP must stand for "high powered" or something like it, because a small dog dose is one every other day. They were around $25 for 60. They have a tip to snip off and squirt the oil on food. Nice idea, except the oil is so smelly it smells up the kitchen. If I get it on my hands it's worse then garlic to get rid of! and the worse part is Frosty won't go near the stuff! Even one drop covered up with his food makes the whole dish off limits. He likes cooked fish, but this stuff is ransid smelling. I don't know what to do with it now. I'm hoping my neighbor with 2 huge dogs will take it. Her dogs will eat anything.
I don't know why I even tried to change to this stuff. I guess thinking the vet knew best. I've given Frosty "Missing Link" ( with Glucosamine) for years. He loves it and it's the Omega 3 and 6 fatty acids. It isn't as potent as 3V HP caps, but probably good enough and he loves it. He hasn't had skin allergy problems since he's been on it, and no red-tear staining.
Some of the breeders I've talked to use regular human Flaxseed Oil instead of Fish Oil, and Vit. E caps that you cut open and add to the food.
