Do LGD's have to be so darn big ???????????? I just want a few chickens and Pygmy Goats, ducks, etc. Isn't there a smaller dog to guard my little flock of animals ?
Greetings @sophiemae and from the front range of Colorado. You could always save the cost of the dog, vet bills, dog food, etc and just buy very strong and secure fencing/enclosures... Depending on where you live, even that may not be enough if you deal with hungry bears, who will and do tear down chicken coops to get a chicken dinner.
Remember your LGD may face multiple predators at one time. Additionally a few weeks ago a very odd character came to buy sheep. All my internal alarms were jangling. From seemingly nowhere my Pyr materialized doing her rolling thunder routine. Then her "sisters" provided backup. Big dogs are not all bad.
I agree partially w/ @secuono since the word "need" was used You DO need good fencing and hot wire (regardless of anything else). And though you may technically not "need" a LGD, if you can afford one (or a pair <or several pair?>) what a great assist to the fence and hotwire as well as just plain great animals to have around for general protection! They are awesome!
