Just that- my border collie was up several times last night wanting to go outside. I had thought she just had an upset stomach after a very long walk (it's happened before) but we noticed the blood in the morning and she's just done it again. Maybe a teaspoon of fresh blood, not mixed in.
She is vaccinated, flea-d and wormed recently, hasn't been anywhere new, doesn't tend to eat anything she shouldn't, doesn't chew at sticks. Otherwise she seems fine in herself.
Does she need to see a vet, or shall I see how she goes tomorrow?
