Regarding the food bowl- No, there is no reason for her to find or indicate on it. I've taught my dog that the food bowl is out of bounds while training. She should never attempt to steal reinforcement from that bowl- and you can see that she clearly understands that concept. She walks right past that bowl multiple times in the video and it doesn't phase her at all. This is Susan Garrett's game called "It's yer choice." Pimg has a choice of stealing reinforcement from there. But I've worked with her to the point where she no longer has a need to. She works right passed them.
Wildo - I haven't had much time either to comment or reply to some PM's lately so no worries.
Your comment above is what I am talking about . What is her reward . The whole thing is a controlled obedience exercise without drive . She finds the box , oh boy lucky me, eats the treat , and walks away . You ask her to go to her crate , which she does obediently. When you have a new find for her you ask her to come out of the crate -- where she is sitting nicely, "good dog" , and she strolls out and does her rounds till she is lucky again. Rinse and repeat.
You taught her to walk right past her reward -- way way too much obedience - and confusing to the dog . If she is to find "something" (the bits in the bowl) she is too find them here there , everywhere and indicate , and not in a select area - which is reminiscent of an agility exercise - too much direction .
For a starter there are too many boxes .
Two would be good.
Use them as covers , not open.
Hide object under . Let dog go back and forth between the two. Once there is a glimmer of committment or heightened interest in one , then YOU go in and reinforce it -- is it here? where is it? , get beside the box show you are happy , tap the box , get her to be more interested look at it , look at you, look at it again, hoping that she will touch it or bark -- but party mode . Up end box , whoa , there it is good girl , you found it, good guy , (celebrate) make the dog feel the reward , which you give her .
That is your strong indication . The dog stays with the location till you arrive to confirm. She can walk around it , nose pointing, look to it , look to you, look back to box, scratch at it , move it around , but she has to stay with it .
