What the crap is wrong with Bennett?!? Pleeeeeasle help me!!!! I need urgent help!!!!?

My dog's a American purebred er spaniel. He ran into my shower and when he came out, he ran around like crazy! He ran under chairs, behind couches, around his play pen, and the bahroom! I took him outside and all he did was run around the patio and run back in. When my dad tried to dry him off, but he scooted his head across the floor and tries to bite/nip at out feet. I need help now!!!!!!!!!!!!!!!!!!!
