I always take my dog with me, he is a patterdale jack cross got him from the dogs trust as a pup and took him with me from the off, the only thing i have to watch out for is his bait eating, loves boilies, i don't let him have them, but if he gets the chance...
I made a big mistake a few years back, he got hold of a baited hook, totally my fault, lucky it was a stiff rig, the line was sticking out of his mouth as he was having problems swallowing the fluro line, had to prize his mouth apart with one fist and reach in with the other hand to get hold of the hook, barbed hook too.
