A fox is extremely unlikely to attack a pack of three dogs, or even one if the dog is larger. You can buy concentrated bobcat urine to set up a perimeter. No guarantees, but it might work. Check with your local county agricultural agent or with your fish and wildlife department ( or whatever y'all call it there) for rabies info and further suggestions. Good luck!
