AIBU to cut off the bits that have been in direct contact with his mouth and use the rest?
He was very neat. He ate one side, so it kind of looks the side of a 50p piece IYSWIM. He only ate about an 8th of the volume of the cake. How wasteful it would be to ditch the rest!
However, I've been told this may be skanky and gross.
BTW, my poor dog has been in the vets on a drip for 24 hours due to this little escapade. But he's fine now we hope.
