Wolf
He actually liked it. He liked the tingly feeling he gets when you talk to him and how it made his tail wag, and you called him a good boy each time. He just doesn't always like it if you do it in front of people like the gang. They would always tease him.
Snake
At first, he cringed. He didn't like it a lot. But each time you kept doing it, it became a 'soft spot' for him. He tries showing no emotion to it, but fails and gets all flustered and flushed. Once you did it in front of Mr. Piranha, and he told the rest, and got teased for a while.
