Hi Max,
How is it going with Echo?
Wait and stay require patience and practice and for me, eye contact. My dogs are not released without holding eye contact. To be honest, I want eye contact with everything they do, so in future situations they revert to looking at me before making their own choices.
The first thing I do with my dogs is teach them to make eye contact. I usually start by celling their name and giving them treats for looking at me and acknowledging their name. Then I teach them to look at me eyes, using treats, and eventualy adding the command later (I use eyes, some trainers use look or focus) To get longevity, I ask for eyes, give a bridge word (in my case "Good" which lets them know they are doing the right thing and to hold it) and then mark the release (Yes) and treat or not treat... I don't always give treats except when the first start. I count in my head before I release them. If they hold it for a second, thats great. When they are reliable at a second of eye contact, I wait for 2 seconds, then 3, then 5, then 10, etc.
When I teach sit and down, I want eye contact before the release. By this point, it is kind of automatic as they are looking to find out what to do next. I ask for eye contact before letting them through a door, out or in their keenels, before eating, etc. It becomes so automatic that I realy don't need to ask them for it and they will wait looking at me until I give them the next command or release them.
This will help on the focus, and also on patience.
At some point she will look to you before she goes for a rabbit or deer or whatever, simply because shes learned to wait for you to tell her what to do.
Let us know how its going!
