Moose just ran full speed into the slider...

He won't let me touch his snout, but when I do he doesn't whine, and also doesn't want me to touch his head. There is no bleeding, and no whining, but is it possible for them to "break their nose" or get a doggie concussion?

he seems fine, right now he is begging for cake!

give him a few moments to compose himself and check to make sure his pupils are the same size.  I am sure it was just one of those embarrassing puppy moments he wished no one saw!!
