My dog pees herself whenever she gets excited, and I don't mean the something special is happening like shes getting some of our left over ribs or something. No its just HEY HEY HEY YOUR HOME! Oh I peed myself, rub my belly. There's a squirrel in the yard bark bark up pissed myself again. None of my friends dogs do this but mine does so does she just have a weak bladder or is this common for dogs?
