I'm glad we haven't had to resort to hot sauce for anything here. It wouldn't work! I was eating one of my favorite snacks the other day, a corn tortilla toasted with melted cheese and habanero pepper sauce and Shiva wouldn't leave me alone. She kept nudging me with that big nose of hers and plopping that huge paw on me. I finally told her, "okay, if you think you want this . . ." and gave her a little bite. WRONG! She loved it. I have a puppy who likes hot, spicy food. Maybe it's because her breed's Brazillian. She tries to lick the empty Negro Modela (Mexican beer) bottles, too! I tell her she's too young to drink (g). None of that explains why Bimmer likes hot food too, though. Give him a piece of jalapeno cheese and he's a happy dog.
A word of advice, though: never Never, NEVER let your dog have any chili unless you're prepared to suffer the consequences. It doesn't bother them in the least. but oh, the stench!
