These “ruff and ready” would-be guide dogs were put through their paces – with the help of Britain's best special forces officers.
Ollie Ollerton, from “SAS: Who Dares Wins”, put the latest round of doggy recruits through their paces near the Guide Dogs National Centre in Leamington Spa.
The former UK special forces solider said: “I’m here to see if they’ve got what it takes. It’s not for the faint-hearted, and this boot camp will prove if any of the recruits are barking up the wrong tree.”
