X2. Its called a “neutral consequence.” If a puppy does something and a good outcome happens, it's a good consequence, and he'll be more likely to do it again in the future. If he does something and something bad happens, say he pokes a wasp and it stings him back, obviously it's a bad outcome or consequence, and he will be less likely to do it again. But it really depends, because sometimes he can take a seemingly (to humans) bad outcome (say, Jerking away or yelling right after he bites you) as a playful attitude in the human, and will sometimes do it again in the future to get that “fun” (to the dog) or energetic outcome again. So sometimes a neutral outcome or consequence is the best outcome because neither good nor bad happens, and he either gets bored of nothing happening, or he knows that that's no way to get attention.
I'm sure you guys already know that, but I always think it's pretty interesting
