I'm open to consider each dog on an individual basis.  If you want to bring your dog, please let me know their age, breed, and experience around livestock.  It is easier for me to welcome an elderly dog, a dog from a low prey drive breed, such as a King Charles Spaniel, or an experienced stock dog with a seasoned handler.  In contrast, a young dog - still learning manners, a high prey drive breed, such as a husky or belgian malinois,  or a dog and owner with no farm experience is not a good match for homestead life here. 

Additionally the farm has dangers to dogs. High voltage electric fences charged enough to keep a woolly sheep from passing are extremely painful to a curious and much more conductive wet dog nose.  I've seen a dog get a shock, loose bladder and bowel, then tremble and for the rest of the day.  A dog who is let wander could go to the neighbors cattle, where, the dog can be legally killed.  

The ewes see unfamiliar dogs as "Scary Wolf!"  Even if the dog never touches them, his simple presence slowes their growth because the sheep are on alert, not grazing.  I can give a clear NO to any  wolf hybrid coming to the farm.  

Sheep milk is higher in solids, compared to goat milk and cow milk,  protein, sugar, and fat are roughly double.  The high solids leads to nearly double the  yield of cheese from the same number of gallons of milk.  Safety is another reason I choose Sheep.  When working with livestock, occasionally an animal bumps or steps on a person.  When a 150 pound ewe steps on my foot it might cause a small bruise, a dairy cow can weigh over 1,000 pounds and a person getting stepped on is far more likely to suffer a serious injury.  Transportation of smaller animals is easier.  I frequently move lambs in a dog crate in a car and I can fit several adult sheep in the bed of a small pickup truck.  In contrast even a very young calf is too big for a dog crate and to move adult cattle a stock trailer and larger truck are needed.   After rain sheep can graze on soft, wet ground when heavier cattle would damage the pasture.  Goats are more mischievous escape artists that challenge fences far more than sheep.
