a poo dog is a highland terrier/scottie dog/westie. they just look like little poo's! whenever you see a poo dog, the rule is to blow a huge slobbery raspberry at it, as you would for other stupid rule things like yellow car no returns, and touching red objects after seeing a mail van.
Rach- Whoa! check out that poo dog over there! hahaha
Dan- *winds down car window, and blows a HUGE raspberry* oh how we love poo dogs.
Rach- Totally.
