Wilfred Season 2 Episode 7 (08/02/12)
Jenna is going away for the weekend so Ryan has to take Wilfred to his big doggy dance recital. They practice, practice some more, and after a post dance rub down, Wilfred ejaculates on Ryan.
He is weirded out and doesn't want to dance with Wilfred anymore. He spends his time with an old friend from his dad's law firm instead. His friend stayed with his dad's firm instead of starting a new one with Ryan way back in the day.
Ryan wasn't happy with his friend, but after hearing his side of the story, Ryan forgave him.
