It looks like you may have more predators than you thought if Hera is worrying about being able to protect the whole pasture. Predator load is what determines the number of LGDs y need, not the number of acres or animals. If she is bringing the sheep back to the shed, Hera may be worried about not being able to protect them in the field. OTOH LGDs want to stay with lambing ewes and newborns because they are most at risk. The smell of lambing and afterbirth carries several miles and attracts predators. If you can keep the sheep closer to the barn so she can check on the newborns and feel that they are safe while protecting the sheep in the pasture, you should be alright. When you have 2 LGDs one will usually take on the newborn duties if they feel there is a threat while the other does pasture duty. They will often trade off duties during the lambing period. With her leg problem and age, I would definitely get another LGD now. If you want a puppy, you have to start looking now in order to guarantee one from a good breeder and litter. Hera will help train the puppy now before she is too old.
If you want to try the 1-year-old cross bred, be very careful. I am not very fond of crossbreds because you don't know which parent they may take after. Some are excellent while others may not be. You will want to inspect the dog and how it interacts with the goats. Goats are often more forceful with LGDs than sheep and will often discipline a playful or aggressive LGD. If this dog is too playful the sheep may not be able to discipline him when he enters an adolescent play period chasing.
I would not agree to take this dog permanently but would ask for a trial period. Female Anatoloans can be very dominant, and Hera may not allow it on the property. Just because she needs help guarding doesn't mean that she will accept another adult LGD on HER property. If she decides to beat up this male and he defends himself you may have a problem. Hera may get injured due to her bad leg. (If a fight happens, do NOT get between them trying to stop the fight! They will be too powerful and YOU will get hurt!) You will need to have an introductory trial period with this new dog to see if she accepts him, if he will submit to her authority, and if he will get along with Bruno. Although a 1-year-old is technically a puppy in large breeds he may go after Bruno.
Also be aware that Komondors have dense mats of corded hair that can grow to the ground. They do not respond well to brushing because of this dreadlock type coat. This long hair will collect lots of debris and need to be trimmed around the legs and face. With the mud at your place, you might not like all that coat. On the other hand, since it is crossed with an Anatolian the coat will probably not be as bad as a purebred. The Komondor is known for being good with family and family pets, but aggressive with strangers. They also need 6' fences since they can wander.
It would be worth a trip to see the dog as long as it is not too far away to look at the dog and judge his LGD abilities. Are you sure that the predator load is so high that you need an immediate adult LGD? Otherwise, I would start looking now for another Anatolian puppy. You can get a female since there is such a distance in the ages. With Bruno on the property, I would not suggest getting a male Anatolian.
Success!
That would be HORRIBLE!!!
