had a discussion the other day with my pal he reconed some dogs are too scared to go deep into some earths even tho they know quarry is down in the depths but i said how does the dog know how deep it is? he just said some dogs are shite and wont go deep into earths think he was referring to mine but didnt want to upset me and say mine just generalised really lol, mine cant find a fox in a dustbin never mind been scared of going in the depths for quarry.....what are others thoughts do terriers know the depths of settes and wont go deep? or could it be lack of nose like mine i think well thats
