Hi Snoop. They are pretty easy once you have the basics....like a five foot fence around their paddock. There is no reason why you can't walk goats with dogs, our's are very good with them and only don't go because of other dogs in the village...they are not streetwise. They only need a baby every two years, some even longer, to keep you in milk. We milk twice a day at the moment but will be dropping to once for the winter, partly to give her more use from her food (there will be less milk) but also because we will be going to the UK for a week so our neighbour will be milking. We have a pet sitter for the rest of the animals, but he has never milked. She lets us know when she wants milking (she is just by the back door) and gets straight onto her platform when she sees the feed bowl. Other breeds will give more/less milk. If you invest in a cream separator you can get cream (so butter), or you can leave the milk to sit for a few days for the cream to rise, but it gets 'goatier' as it sits. It took me a week or two to get used to the milk in coffee, but I always use it from the last milking and it just tastes creamy now. I prefer to freeze the milk for cheese for the same reason, you get goaty cheese if the milk is kept in the fridge for a few days.
For food, they get any spare branches from edible trees (info on the net) an hour or more browsing the verges/hedgerows around the outskirts of the village. You will be able to do the same i expect, but check your local restrictions. I believe you can't let them roam about in the UK now, but I might be wrong. In Spain you might even have a village herder who will take them out for the day as we do here if we wanted him to, saves on food for a nominal cost. They get goat nuts and oats wen milked...with a tiny amount for baby, with veggies. Most spare veg...dying beans...maize stalks (not cobs) cabbages, courgettes, cues, watermelon, beans, chard etc, toms and peppers in small quantities, weeds, sunflowers. If you chuck anything over the fence there's a stampede of goats, ducks and chooks all going for their favourite bits. Hay is available at all times. They burp a lot and some people give them bicarb in a bowl for them to help themselves, but I think that's when they are on a restricted diet. Any poultry food needs to be kept out of reach. There is plenty of info on their care and what they can and can't eat. Our's are friendly and cheerful.
One thing I have picked up, some goats produce very goaty milk, so if you can, taste it. Our's came from a friend so it wasn't an issue. And although you can keep one, they get very clingy towards their keeper and will try and follow, so two is best, like we have, mother and daughter. Mind you, they recognise Dave's car turning into the lane though they've never seen it, so I always know when he is home.
