This evening, I went out armed with halter, rope, antibiotic spray and fly goop. George came up to greet me, and then allowed me to leave him and go over to take care of Bridget.
After I had removed Bridget's halter, George came right over.
Bridget is acting rather sad and crestfallen. Her leg is swollen a lot, but she is not lame. I may call the vet on Monday - we'll see how's she doing.
