Hhhmm so you think every situation can be solved by positive you try it with a red zone aggressive dog that wants to rip another dog or person to shreds or has and let's see if hanging food and praising the dog or ignoring it works.
Yes, if you are a first rate trainer and know what you are doing.
It's doesn't work in all cases I'm a professional dog trainer and have been for over twelves years and have studied and been to many seminars on every type of training method and I have no problem saying that.
I was a professional trainer for 15 years and trained not only dogs but many wild animals. I have trained animals who had no intent or desire to please me or be my friend. Killing me was the top priority on their mind.
I too have studied in many seminars and with many top notch professional trainers. I have used pinch collars and choke chains. I have jerked and pulled dogs all over town. That was before I learned how to train effectively using 100% positive methods.
You can't always use just one method of training it's not just the dog or the person your training.
Assuming the animal isn't brain damaged, any animal can be trained (I prefer the term "teach") using only positive reinforcement IF the trainer is competent. I have seen anything from rhino's to gorillas to elephants to lions and tigers and many other so called dangerous animals trained this way.
There are so many different options available and if your smart you read up and know all of them otherwise you limit yourself.
I know them all by experience but it is down right cruel to use pain to get an animal to perform a behavior you wish if you can get the same behavior without pain. If you are competent with that species, you can.
If you don't agree with it don't get on other people who do.
Well, I do. When I see someone using pain it is showing me that the animal is smarter than the trainer and the trainer has no other way to control the animal, whatever species the animal happens to be.
Because you have no idea what their situation is or their dogs.
Don't need to know. If they are using pain, they are wrong and/or ignorant. One or the other. If ignorant they need to get educated. The days of the compulsive trainer are quckly coming to an end. There are fewer and fewer of them every day. The end won't come too soon for me.
I don't have a problem with opinion but don't tell someone you don't need it because you really don't know. State your preference that's all I'm saying
I do know and you don't need it. EVER! If you think you need it, so some research and/or ask for help.
As you can tell, I don't have a lot of patience with trainers who still insist on using aversive methods in todays world.
