On Sunday, Shiloh, our 4 year old beagle who is sweet as can be, broke his dew claw (his thumb nail). This requires a trip to the doctor, or since it was Sunday, the emergency vet (cha-ching). It's quite painful - they have to pull the nail out and he has to keep a bandage on for 2 days.
It would be impossible to guess the number of times he got that thing off and I had to re-bandage it. He's better now, but that chasing and repairing really cut into my knitting time!
