After Joey was rescued, he recognized Albert's voice when

Joey recognized Albert's voice when he came in the stable to clean him up.

‘You’re not on about your Joey again?’ The head that came with the voice leant over the stabledoor. ‘Won’t you never give it up, Berty? I’ve told you before if I’ve told you a thousand times. They say there’s near half a million ruddy horses out here and you joined the Veterinary Corps just on the off-chance you might come across him.’ I pawed the ground with my bad leg in an effort to make Albert look at me more closely, but he just patted my neck and set to work cleaning me up.
