Last night I was in bed with the dog watching tele. Yes, I know, but my hub works away a lot! It wasn't late, maybe half 9 and I was later going to put him downstairs to bed in his crate.
Suddenly I realised that where he was laying there was blood, quite a lot, I'd say a wine glass worth. I put him in his crate while I cleared up (duvet cover ruined, duvet stained but can't justify replacing). Then I went and checked him thoroughly but could find nothing wrong. I was up and down fretting throughout the night, but he seems fine and has had a great run today. Could it have been a nosebleed?
