I was saddened to read that our friend Tom had been subject to some saliva which caused beeping. The setter in question was probably swept away by how much fun Tom was being as he ran on*. An ineffectual owner is a curse in situations like this.
Anyway it set me thinking in my special collie way of how humans could all do a bit more thinking sometimes...
*Setters take an awful lot of outrunning, Tom, thumbs up!
