So excited that his owner is home, he just has to sing.

The pug's owners posted this video on YouTube...

Our pug is deaf, so he is not to sure what he is saying so when he gets exited he starts "singing". He is one old chap and very friendly, 11 years old! He is a healthy dog and loves to be around people, sometimes he even "sings" when no one is around. I can assure you he is not in pain, but is just excited.
