Even working dogs on farms are treated differently
Our working dog only gets chained up occasionally because someone complained about it being loose in the farmyard during lock down 1 (there is a footpath runs through). If we are away from the farm and have no use for the dog that is now when it gets chained up.
It otherwise roams freely in the farm yard minding its own business except for the wag of a tail at passers by, or racing to us if it hears one of us whistle for it because there is some sheep work to do. It sleeps in corner of a warm barn if it wants to, but can often be found fast asleep outside on concrete in the snow if it feels like it.
Its a working dog, its absolutely filthy, exceptionally fit and healthy and has a wonderful life living about as naturally as it is possible for domesticated dogs to do. Its bred for working as a sheepdog, its highly intelligent, bored easily and needs to run for several miles a day.
If we let it in the house it wouldn't roam freely. It wouldn't get to hang around the sheep pens feeling important, or potter round the barns sniffing out rats. It wouldn't get to run joyfully, after the quadbike over several acres, splashing through rivers, dodging rocks and trees. It would get fat and unhealthy and bored. It would be a miserable life for it.
I'd rather see a farm dog outside than a fat, genetically mutilated lapdog locked up for hours on end in a semi detached, bored and lonely and unstimulated whilst its owners were at work.
