If you leave horns on your Goat

 In the early 1980s my then wife and I bought two milk goats (one and Alpine and the other a Nubian) from the local Zen Monastery in Mt. Shasta which at that time had at least 25 or 30 goats. So, we brought them home to the acre of land we were renting into a shed that became their barn easily. They became pets and milk goats as our older children were all around 5 to 8 years of age then (the three of them two boys and a girl). We drank the Goats milk as a family and made Feta Cheese also with it by running it through a cloth screening process and letting it sit and congeal into Feta Cheese. We also sold Goats milk and Feta Cheese to friends who wanted to buy it then too. We lived on the corner of Lassen Lane and Old Stage Road then in an older house. I'm not sure it is there anymore. Then we had to take back the Nubian Goat because she got mastitis and we didn't have money for a Veterinarian then because we were also raising 3 kids. So, we kept the Alpine Goat milker for a long time before selling her too eventually when we moved out onto our land 20 to 30 miles east of the city of Mt. Shasta onto our 2 1/2 acres with an A-Frame I and my father and my wife and kids and friends built there. The land had a spring on it for water too. 

The point is if you leave horns on your goat they can get entangled in things and they might horn you if they are in a bad mood. However, the good part of leaving horns on your goat is that they can then defend themselves against most things including wild dogs and raccoons. However, if it is a mountain lion likely their horns might not be enough to stop a mountain lion if that is what comes after them when you aren't there or are asleep at night.

Later in the SF Bay area we rented land about 7 acres of ranch lands and also had a pygmy Goat that we called Barney and we left his horns on so he could defend himself. However, sometimes he knocked our 4 year old daughter down with his head by head butting her from behind playfully. He might butt us too but at least he could defend himself from wild animals and dogs. So, removing a goats horns might be easier for you to deal with but more likely that some roving wild animal will kill them when you aren't there to protect them. It's a little like declawing your cat. They just won't survive outside at all if you declaw your cat, especially the front claws they use for climbing trees.
