Google nest still can't tell the difference between alpacas and humans! Do you have any cameras? Where? We normally track gates and water buckets/ feeding areas!
I have some farm dogs I LOVE to death, total goofballs. They're not exactly trained but one did help me find a goat the other day... and the other broke through the fence to join us, so pro/pro 💖
I only have 2 who's hooves get out of hand. Those I have to trim whenever I notice them start to get twisted. The rest seem to manage okay with a combo of asphalt and dry barns
