CollieMan - that's a great cue
Pulling the lips back is a submissive gesture (how we're talking about it in this thread, lol). That's probably why bunch of you have seen it while doing obedience or petting. Greeting is definitely a good time to catch some dogs too.
I read an example of this in a training book (I think it was by Brian Kilcommens) - a young Standard Poodle was going to be euthanized due to 'aggression', because he would 'attack' all visitors, jumping up on them and try to 'bite' etc. They hired a few different traditional trainers who instructed to use various physical corrections, but the dog only got worse. The author was the dogs last chance... he entered the house prepared for a vicious dog, but was greeted by a big fluffy Poodle with a submissive grin who wanted to cover his face in kisses!... With each correction that had been given, the poor dog submitted more and more, making the 'trainers' believe he was getting even worse and applying harsher corrections :dogohmy:
Here are some ways to get the behavior:
- petting excitedly and using a high-pitched voice
- putting your face in theirs while petting
- blowing gently on their nose
- catching them just before they sneeze
- massaging their ears
- 'tickling' the corners of their mouth, especially if they are panting
- gently brushing their whiskers forward
- fold their lip in so the hair touches a canine tooth
... the last two will get more of a 'snarl' look, and the others should get more of a stretched smile :dogbiggrin:
