Some people love liver, some people don't and never will. I fall into the first category, and think it's scrumptious. There's a pate from Julia Child we make that has currants and brandy in it (and a little old-fashioned deliciousness in the form of good-ol' butter). But if you don't like liver, that approach isn't going to hide the flavor.
Like others have said, you can work a little bit into stews and sausages, and it will make the flavor much richer, but won't overpower it with liver taste. Also, country-style gravy is superb with liver in it, although I use liver chunks and not ground-liver. (I do love my meat grinder, though, and I grind just about everything else.)
And even if the dogs are already spoiled, it wouldn't hurt them to get just a little spoonful or two, would it? That's the fun of having dogs, is getting to spoil them!
