Hmmmm aren't there parts of an animal you wouldn't want your dogs eating? I know for me there are..like what about all the animal by products in nasty food.. I guess I'd have to know the nutritional value in certain parts to feel good about giving them. It just seems really odd to me to give my dog strange parts of animals.. I realize I could just be weird for thinking this way, but I still do.
I was vegetarian and vegan for many years and eventhough I'm not anymore, I hardly ever eat meat and if I do it can't resemble meat in any way...I can't even watch people eat ribs or gross stuff like that...so I've never been the same and I know that affects some of my views and what I can't get past.
But I was just wondering. I tried those bully sticks just to give them a variety from the same bones they always get but I still think it's super weird for a dog to be chewing on a ya know what, lol.. I don't know, I guess I just can't get into this stuff as much as some people. I try! But it doesn't come easy for me. They'll have to be sheltered and just get bones I guess. Life is tough.
