Gumbo won't back away when I open the oven to take out food and he practically sticks his head in, I am constantly yelling at him to Get Back and even pushing him back because I am so afraid he is gonna burn himself on the oven door. Has this ever happened to anyone? Same thing about my flat iron, he is always being nosy and smelling it when its on hot. Im always paranoid he will burn himself. Do dogs feel pain from burns? Should I just let him learn the hard way and burn himself so he knows not to do it again? Also, he stepped in a huge ant bed a few weeks ago and it was crazy to me that he didn't show in any way he was affected by it? I couldn't tell if he got bit or not? That's what made me start thinking about pain and their tolerance to it? I step on his tail all the time and he doesn't even move or flinch. Interesting subject that i would like to hear some feedback on. Thanks!
