I'm told a llama with sheep, or a donkey, will help protect the flock. There is a large white dog breed that is bred and lives to herd and guard sheep, and often live with their flock. So if anything shows up, they have protection.
As for cattle, we had Charolais on the farm. Large white cows, meat animals, and they were insanely protective of their calves. They could and were crossed with part bison (bull was 3/8ths) and would throw a very large calf (some were close to 90#, I know I helped pull them sometimes) that grew well and fast with good meat. Some came out 'pink' when we had Hereford in the cross. We later got mostly Herefords and Angus and kept those old Charolais cows with the herd as they helped protect it. That calf bellered and she'd come over 4 strands of barbed wire to get you, one we confined in the barn as we knew she was going to have problems and she climbed/crawled an 11' fencing (we added boards, 2x12's) and got out and had it outside the barn in a blizzard in March (I helped pull that by pickup headlights). Or she'd tree you on the windmill tower, and someone would have to get the big tractor and bucket to give you the ride of shame out in the lifted bucket with her dancing around down there wanting to stomp you into a bloody booger. Most of the time they were no trouble, unless her calf said something. If you want a cow that can protect herself, leave the horns on. You might end up with one or two in your herd that are kind of antisocial but are wicked in defense, and you keep them for that. We never kept a bull but would arrange with a neighbor to take one of their bulls for a few months, and boy can they eat. That is why you usually don't keep a bull unless you're running a large herd, and usually trying to raise breeding stock (and bull calves to sell at auction). AI is often cheaper and easier. When the folks had milk cows it was almost always Holsteins and an occasional Guernsey or Swiss.
If you want to do things right a blue heeler or border collie that is trained is a good cattle dog to help you work the herd. I'd say the blue heeler is better with bulls and that border collie lives to work. They can be very good dogs but they need to be trained and given a job.
