When the kids were all home we always had a scrap eating dog around. We like dogs but there is no one around any more to take care of one. When the last one died we decided not to keep one any more.
However, my sons both have big old dogs that they bring over to visit grandpa.
Any left over meat or fish that normally would be thrown out, I save in the freezer. When I get enough, I make doggy cookies.
Chop up the meat, mix with an egg and some flour until it is a cookie dough consistancey. Then I bake, freeze and store them in a zip lock bag. When the doggies come over I pop a couple in the micro wave.
Now when they come over they stare and whine at the freezer door until I give them their treat.
