For the past few days I've noticed some little spots of blood on the floor near my dog (big mutt - looks like a cross between a collie and a foxhound). Two weeks ago, he was bleeding from his left eye - and the vet said it was from some kind of infection and gave me cream to put in his eyes twice a day. I've finally determined that this new bleeding is from his nose - seems to be just the right side.   His breathing seems to be a little louder at times. His nose seems fine most of the time, but everyonce in a while, I can see just a small trickle of blood come out. His vet is closed now... I'm not sure what to do! Any advice would be appreciated!

He's had allegies in the past, so i did just give him some benadryl.
