My dog sometimes pees on the grass when sees me after a long day, although he's not doing it in the house, only when I meet him in the garden. While he's peeing he's also shaking and making strange sounds... It's kinda funny... He seems like he's just too happy to express himself
Post bath he goes into a euphoric frenzy running thru the house and rolling around on the carpet. He is so happy that it can turn a bad day around.
