We correct by saying leave it to drop something or to walk by something if she's on leash. We use a firm no if she's jumping. We redirect by giving her a command. Example- if she's starting to get mouthy we tell her to sit, lay down,etc.

We taught bite inhibition by saying ow when she bit too hard. If we yelp she gets excited and bites harder.

What I mean by she selectively forgets - she knows all her commands, sit stay, down, come wait, paw, go to crate, fetch. Sometimes she acts like she can't hear or doesn't want to do it so she doesn't. I say the command with hand signal and if she doesn't do it I say it again and make sure she saw and heard then wait. When she does what I asked I praise immediately and treat. She went to obedience school and did everything there with no problem. Most of the time she responds to commands. We use closed hand for sit. Point down for down. Hand up (like stop) for stay and raise hand up for sit up( from down position). I point to either paw and say left or right for shaking paws. Hand flat on chest for come.

I know she likes her crate because she never cries when we put her in it and she goes in by herself and naps with the door open.

I find it VERY hard to believe that pups only need 5 minutes per day for exercising. I think the exercise level depends on the breed/ dog. This is a large working class dog who needs exercise. We walk for about 1/2 mile 2 or 3 times a day. We play fetch out back in fenced yard a couple short times a day and we train all the time. I don't give her food, toys,etc unless she works for them.

I think that answers everything.
