unknown origin of bleeding

My rottie/lab mix, Zorro (15 1/2), is already dealing with degenerative myelopathy (the canine equivalent of ALS).

Twice today, I was sitting near him, reading, and heard him licking the rug (which he does, rather neurotically).  There was a rather large blood stain on it (maybe 2-3 tablespoons).  I looked in his nose and mouth, and checked his ears, eyes, penis and anus.  No sign of blood anywhere.

I checked all paws and legs.  Nothing.  I felt all over his body-- no sign of any blood.

About 2 hours later, it happened again.  I checked again.  Still nothing.

So this has me stumped.  It doesn't seem to be an emergency so I won't call my vet on a holiday weekend (Canada Day).  I'll check with her on Tuesday.

In the meantime, I'm just wondering if anyone has ever had such an experience and if you found out the source.

I'm thinking it has to be his nose, but a Q-tip inserted soon after the episode should have had some blood on it; it didn't.

Any ideas?

Thanks.

Did you check his limbs and feet? He could have stepped on something sharp, bleed a little and the wound is now closed. It is also possible that he could've been eating a mouse or other small vermin without you realizing it.
