I've been around dog folks pretty much most of my life and I've heard a gambit of weird stuff but honestly I wonder where some of this comes from.

Today I was told I was keeping my dogs wrong by not letting them correct each other because by not letting them do so they will be doggie socially inept and never truly get along. I just thought - yet somehow they know which end to sniff? I certainly didn't teach them that.

I swear I get the won't bloody meat make your dog mean thing on a biweekly basis. I know I feel particularly feral after sushi and cherry cool aide. Was there a movie, ad campaign or something this came from?

At least twice a year I hear the tie the dead chicken head around the neck thing to cure chicken killers. Personally I think my dogs would probably love that, truly a collar any dog would love. I bet it would attract other dogs.... and raccoons. Maybe I can start a new coondog collar and leash line. I'll call it Pepe le Wooof.

I honestly think it's the natural human tendency to veer towards extremes.

As positive training methods gain visibility and acceptance, a certain chunk of people are going to veer to the far opposite, and reach waaaaaay back for training ideas.

I've always wondered about some of the things I've heard about over the years.
Letting dogs correct one another
Most don't,I do. I wouldn't recommend it for most folks. My dogs have always been a part of a pack but I've never had one of them NOT know who the pack leader is. I've always picked my own dogs and brought them into the pack as pups.
Even when I had 3-4 terriers they always ran together and I never had a serious fight.
bloody meat
"I" believe this comes from a dog normally being more possessive when it eats raw.
My two intact male GSDs are kenneled or in the yard together 24/7. When I feed them I put both bowls (kibble) on the ground about 6ft apart and go back in the house. NO problems.
Give them each an RMB and I wouldn't think of leaving them alone. They can hardly look at one another without growling. It doesn't make them mean but it sure makes them possessive. I can pick up the RMBs with no second glace from either dog.
Dead chicken around the neck
A friend of mine had one of her hunting terriers start killing her chickens. She did the wire it around the neck thing and after a couple of days that little bassid terrier was strutting around like it had some expensive parfuuum under it's ears.
There is probably just a tiny bit of fact to most old wives tales but then folks get hold of them and play pass the message. Ask the 10th person what the message was and you won't even think they are on the same subject.
JMHO of course!

I think in some circumstances, yea the dogs should be able to correct eachother. Like a new puppy and an older dog. Of course its the human that maintains order and makes sure the dogs behave but I think on a certain level it not unhealthy.Young dog learns from older dog that certain things arent acceptable- theres no stress for either dog in the process.

Many folks here won't let a young puppy interact with a older dog, so there would be no reason/need for a dog to correct a pup. I do think that there is stress involved for a puppy when a dog corrects it, even if it's a relatively mild correction. As with any training- a correction is negative. Negative things bring about stressful feelings.

Quite a few sport/working dog people want a pup to feel he's the biggest, baddest puppy in the world for the sake of building up a puppies confidence, which can benefit work later in the dogs life. As few corrections are given to pups as possible, and great lengths are gone to to ensure that the puppy never feels intimidated by a older dog.

Just another view point. I don't want another dog teaching my dog what is acceptable... thats what I'm for. I don't want to have a dog pack, and thats what I feel you'd get, letting a pup be raised by an older dog.

IMO, It is my job to monitor my dogs' behavior and catch a problem before it starts. I feel that dogs correcting each other can lead to tension between them. If I can redirrect before there is reason to correct; it works out for all of us! I have actually gotten after my older dog for trying to correct the younger one. It only happened once, 18 months ago when Haz was new to our house. They get their own space when needed and no problems ever.

I tried the dead chicken. Twice.
It is super gross and doesn't work at all.

LOL! Good to know Betty! Thanks. (I'd never heard of that one before this thread. Quite the interesting idea.)
