Not typically, no. Dogs, though they can be regarded as part of the farm if they reside on a farm, are more of a companion animal than a farm animal. Even if they are used for work than for pleasure like those dogs that live in cities and towns.

no, farm animals are sheep and cows

Bluebell is one of the three dogs from the book "Animal Farm. " The other two dogs are named Jesse and Pincher.

farm dogs and herding dogs, uh, that's dumb there the same thing! police dogs can be a number of different breeds, they can even be herding/farm dogs. so you'd have probably quarter wolf, quarter some type of herding dog, quarter some type of a different breed farm dog, and quarter whatever breed the police dog was.
