I sometimes eat my dog's fur
What makes you want to eat fur?
It tastes like cheese to me and I like it.
Eating dog fur doesn't seem very healthy. You shouldn't eat things that aren't food. You might want to see if you have some kind of nutritional deficiency that's making you do this.
It's fine, it's just fur. It will be out before long.
You should not eat it because it is not meant to be eaten. I think that it could actually get stuck in your digestive tract.
