My small herd of goats is in need of a guardian. We have coyotes here and 50 acres of range. I would like a short-coated breed and remember seeing one, a Maremma? I think? Can't remember. It is absolutely miserably hot and humid here in the summer and gets to freezing in the winter. I'm in south middle TN. What breeds or cross breeds can you recommend? Also, I see LGD's advertised which have been born and raised with the goats, as opposed to with a family, being new to LGD's I am guessing this is preferable? Am I supposed to leave him or her with the goats all the time? Is one sufficient for a herd that might get to about 15 - 20 eventually (brush control work) or should they have a dog companion? Thanks in advance.
