, (Humour) Actually, I’ve no idea what the requirements are for hiking with a dog! I know of dogs capable of rescuing a swimmer in distress, dogs able to abseil from a helicopter or locate people buried in snow or rubble... but as for yours, as I don’t know the animal, it’s very difficult for me to offer an opinion or advice.
