Buster and Jack, it seems, have found a way to keep their friendship alive despite the distance and the infrequency of their rendezvous.
"It's very sweet," Buachalla said. "I have no idea if this is normal for donkeys, but my dog is rarely so interested in other animals as he is, in particular, with Jack."
This year, Jack had a surprise for his fluffy pup friend - someone he really, really wanted Buster to meet: his new donkey companion, named Jill.
"These are actual names," Buachalla said. "I checked with their owner!"
Jill and Buster hit off, too. (She's probably heard all about him.)
