Sally, I'd hazard a guess the blood could be down to irritation from fried rice and chicken.
Keep an eye on it though and if you see any more definitely call the vet for advice.
Pip started out in the second kitchen bed last night, but then chose to go into his crate!
He slept from 11.00 pm to 5.00 am. Dh heard me open the back door and came downstairs to say he'd stay with Pip for the rest of the night, so I got two nice big chunks of sleep. 
Didn't have the guts to sneak upstairs in the end, given it was the neighbour's first night back and they'd had a really long drive home. I think we're reaching the point where it won't be a problem though, as he's happy to go in the garden without me and will wait by the dog gate in the kitchen while I go upstairs and put washing away etc, without so much as a whimper.
Left him with my Mum and the dcs this morning as I had to pop across the road to the vets to pick up his antibiotics, because they accidentally left them at the main branch yesterday. Apparently he had a ball without me here to supervise and was leaping on and off the sofa biting all the cushions!
When I got back he was curled up in his bed looking angelic. 
I have a gorgeous photo of Lurcherboy and Pip cuddled up together in Lurcherboy's favourite bed this morning. Dh was with them and said Pip was obviously really tired and sat there swaying with his head drooping, considering whether or not to try it, then just climbed in and curled up around (and atop) Lurcherboy's back. Dh thought Lurcherboy would object, but they both just snuggled down and went to sleep. Aw.
Dh has the usb cable in his work bag though - so can't download the picutres until he gets home.
Lurcherboy has also taken to supervising Pip in the garden. It's so cute, they kind of patrol the perimeter together, with Pip copying every sniff and movement his big brother does.
