I apologize if this information is already somewhere else on the site, and I failed to find it. I'm trying to plan a yard and shelter for two pet Nigerian dwarf wethers and need to know the space requirements. (It's legal I checked.) I don't have other pets or kids currently, So I can easily shower them with attention, lots of play time, trick training, walking, hikes ect. And I'll give them plenty of things to keep them entertained while I'm away too. I live the Colorado mountains where it is very dry, and the winters are really cold. I'm not sure how high the fence should be, but we do have a bears in the area, and sooo many wondering off leash dogs. Suggestions? Also when walking the goats on a leash, would a dog whistle keep off leash dogs at bay? I could carry mace too for just in case. But still I'd like to scare off the dogs long before I have to mace them. Has anyone had trouble with this sort of thing? I'd like to take the goats to visit the old folks home nearby, but figured it wouldn't do to have them peeing and pooing on the floor. Is it possible to train them not to go inside, so long as the visits are short? Has anyone tried this before? Thanks for any help.
