Yes, I agree that they don't understand punishment. But the guide says you can gently lift their chin to let them know not to do something.
Do whatever works for you and your pigs, we're all different. I'm not saying not to, just passing on my education.
I believe in strong bonds with your pets, it's not hard to do and you will enjoy your pet more for its entire life, and in return, they will also enjoy your company and unless a unavoidable health concern arrises, I believe it will also extend an animals life span, you're their will to live if the bonds there, and it's never to late to begin trying!
I'm just saying in my studies, which are up to date. I do a refresher course every year. Punishment does not work on guinea pigs and rabbits. Positive reinforcement does. Their brains physically do not understand it and they're likely to be confused, become depressed and more stressed/ anxious.
If they're doing something you don't want them to do, show them what to do instead.
Example: cage biting, I got fruit tree branches and weaved them through the lower grids. They chew the branches instead, good for their teeth also. If they continue for attention. Turn your back and ignore, as soon as they stop reward with a treat. Ideally clicker training first would be super useful here. I'm halfway through clicker training one of my pigs, maybe I'll do a thread on it once completed!
Example of positive reinforcement vs Punishment (I'm using a dog as an example sorry!)
PUNISHMENT: If a dog jumps on you, and you punish each time, they will learn. But depending on the dog and the punishment you're using (and their reason for jumping) you will need to punish successfully eveytime (can't be tired and lazy one day and let them get away with it or you're back to square one and have a super confused dog) they will need a minimum of 30 repetitions or more before they even BEGIN to understand, then more reps until they finally do. Usually 10, sometimes more. This will weaken the bond between you and your pet and you will need to do other extra fun activities to try and restore / maintain it (more work)
Summary: it takes longer and is more stressful for all involved.
POSITIVE REINFORCEMENT: If your dog jumps on you and you ignore it until it has all 4 paws on the ground then quickly reward, you'll only have to do this 10 times in a row each time the dog jumps. Once the dog learns to keep his feet on the ground.. you can introduce the sit.
If you introduce the sit first here.. some dogs will get it.. some dogs will not. You will accidentally teach them that sit is a 2 step command. Part one: jump on human. Part 2: sit. Part 3: human should give me reward. This is much harder to fix than the jumping itself as you've accidentally taught them a command.. that they liked doing anyway!
Summary: positive reinforcement is faster and strengthens your bond AT THE SAME TIME, what a bonus. Less work!
I'm not telling anyone what to do, just laying out some stat's and facts and free information that my clients pay for
I met a chihuahua once, when you said sit, he leaped at your thigh, nipped it, then bounced into a sit. It was very hard to keep a straight face in that consultation
Happy training
