First off what is a wether?A wether is a castrated male goat.He will not stink like a buck nor will he go into rutt.
Why you say do a lot a breeders recommend a wether as a pet?I personally receive many e-mails with requests for does or doelings just for pets.They dont want to breed but want a friendly goat that will be a nice companion.
For people like that I suggest a wether.Why you say?Because wethers tend to be friendlier then does, are very loyal and are just like a doe basically because they do not have any of their male undesirable traits.They also are in a way better to have around if you dont like to deal with a doe in heat (check out detecting a doe in heat for more information).
I have one wether and he follows me everywhere, is not as ornery as my does and requires a lot less work.Of course I am not breeding him so that cuts down on my work load with him, but that is just my point.He is able to be a pet, plain and simple.
Wethers require a lot less food then a doe or buck.A handful of grain twice a day plus hay is all they need (check out diet/water for more information).
So if you are looking just for a pet or a companion for your doe a wether, or two, is just perfect.
