@wildpotato First off, I’m loving this exercise and the fact that you are putting so much effort into training your goats!
As to the boredom and your theory of yelling due to lack of stimulation – if we were talking about dogs, I would definitely agree with you. In dogs, barking releases endorphins, so barking is often a symptom of anxiety. Could the same be true for goats?
I know there are Kong toys which goats could use. They may give them a longer period of fun than the milk cartons. I found an annoying video. Here is the toy the goat in the video is using. It takes my dogs about thirty – forty minutes to empty one of them, depending on how big the treats are and which dog is doing the work.
We had a petting zoo at a school I went to, so I know what taking an unwilling goat on a walk feels like. You mention luring. I’m guessing that timing is your issue, here. There are different kinds of reinforcement. Things which an animal will enjoy without any training are called “primary reinforcers”. Examples are food, play, companionship, etc. It is possible to train using these, but…the brain reacts stronger to secondary reinforcers – that is, the promise of good things to come. This is why clicker training works so well – it promises treats, and our brains go nuts.
In leash training your goats, the secondary reinforcers are working against you. Goat stops, you wave a carrot to lure her forward…you have just reinforced the stopping, because that’s when you gave the promise of food. Instead, try giving that promise while your goat is walking nicely. A clicker would work perfectly, here, and it would also make sense to use the environment as a reward. So, how about having some designated grazing spots along the walk, or a patch of extra-tasty stuff planted somewhere as a goal?
Why did the fencing help? Are the goats more sheltered now, less triggers to yell at? That’s something to think about: Can you block their view of your windows, for example? Sometimes, less input is all it takes.
So, they are yelling for attention – when do they stop? Do they want you in their area, and yell for you to come? Do you need to be touching them? Would they be interested in food as a reward at that moment?
If you think about it, the clicker is your remote-controlled reward. If it’s conditioned right, your goats are feeling happy as soon as they hear the click, and they’re brains get the message of, “Yep, right thing to do” in that exact moment. So, you can probably work this out.
One last question: Do both of them yell at the same time, or is one starting and the other joining in?
@keobooks No, dogs do not bark because they believe they are alpha dogs. In fact, there are no alpha dogs, because dogs are not even pack animals. I’m going to comment on your source, as its content could be dangerous for first-time dog owners:
“In a natural state, dogs would live their entire lives within the closely structure social order of their pack.”
In a natural state, dogs would scavenge near humans, individually or with a partner.
“Always praise your dog as if you own it. Put your hands firmly on the dog. Hug the dog.”
To a dog, a hug is something to endure because humans like it. Dogs do not typically see hugs as praise. That’s why so many bites happen when children try to hug the family dog.
“Hands on may mean a collar shake, a leash correction, a surprising assist into a sit or down.”
In other words, pain. A dog’s skin around his neck is incredibly thin, and his larnyx is just as sensitive as ours. Yes, leash jerks hurt. Anyone arguing against that is kidding themselves. A “surprising assist into a sit” is an excellent way to make your dog hand-shy.
“For particularly dominant dogs, make it a down-stay, and even more submissive position.”
There is no such thing as putting a dog into a submissive position. Submissive positions are assumed, voluntarily. If they are forced, they’re meaningless. No matter what Cesar Millan wants us to believe: Wolves to not throw each other on their backs for disobeying.
Barking is most likely to be motivated by fear, boredom or frustration, in my opinion. There are many more reasons why a dog might bark, too many to list – but those three are the ones I see and hear about most often.
