Back before the ban my opinion on a alrounder is a dog that would work with the ferrets, work on the lamp catch the odd daytime hare ( night time too ) retrieve shot game birds ect even in water and if the chance came along deer too also a guard dog in the home and out when things got a bit hot ..an old type poachers dog if you like ...and work fox day and night also with the terriers .does a dog exist ? who knows the closest i have had would do all of the above not in big numbers but he did and was seen many times doing it .
