Okay! Cause I don't want Cesar to interfere with our net-love.
I also want to say generally... as an amateur trainer, I do find it overwhelming sometimes because there are different training techniques and people are so vehement that only theirs really work. I've read to gently push a dog's hind quarters to force a Sit if they aren't minding you, and I've read you must NEVER do that (literally, NEVER) with a small dog, because you could break a bone.
It's not like if you want to learn algebra, and all you have to do is pick up a textbook, because basic algebra isn't a growing body of knowledge.
However, just because there are conflicting opinions and experts who are of course biased - they're human, they are going to be biased - doesn't mean there is not a lot of really great information out there. I urge anyone who is interested in training to read online articles, watch videos, read books, take classes, go to sessions, etc etc etc. You may have to sort out what you believe and what you don't, but without a doubt, you WILL learn a lot. That's my experience anyway.
