I, too, have a small property. I'm adopting a 4-yo what looks to be a collie/shepherd cross this weekend. The people she's coming from have 1.5 acres and have never had to put up a fence for her. I did research the cross, and they are supposedly quite amazing. I'll have to let everyone know how she is, because I can't afford fencing a property that I don't own, plus fences don't keep coons out.
Electrical poultry netting will keep raccoons out. I use that and dogs. It is not a one dimensional approach when it comes to predator management. It is not just dogs, dog breed, fence, poultry breed, forage base, or your husbandry / dog handling technique. It the combination of this.
