Just a few suggestions and a couple questions.

First the questions? How long (seconds) does Nebo focus on you before he turns away without distractions? How many times a day do you practice with him? If you throw a piece of food on the floor in front of him when he is focusing on you will he lung for the food or remain focused?

My main suggestion is to take his kibble at meal time and make him focus on you before he gets fed. This will be a couple times a day at least. I take about 10 minutes and work mine before feeding when I work on attention work since this is really the foundation for all other obedience work. I take kibble in my fingers and then extend my hands all the way out to my side. the dog is sitting in front and his eyes must stay on me or I break out in a OK - lets try it again voice and start over.

The main thing to remember in attention work is not to push the dog too fast. If you consistently get 5 seconds without distractions then go for 6 the next time. You must get atleast a 9 out of 10 success rate before moving on to 7 seconds. Your goal is to get to 30 seconds without distractions right now.

After you get to the 30 seconds, then you throw in non serious distractions. This would be something that doesn't really throw Nebo into a frenzy (such as dogs). When he breaks attention you need to step out of your position give the OK - lets do it again phrase and start over. This is all with his meal! If he doesn't focus correctly put the bowl on the counter, walk away and then wait about 10 minutes if you want and try again. The idea is he needs to work for his food.

If he is highly motivated by food this will work rather quickly and he should be doing great focus work (even with distractions) in a short period of time.

Another suggestion.... on nights when you go to class and know there is going to be a high distraction level, don't feed Nebo first. Wait till you get home. Talk to the instructor ahead of time and ask if you can work on distractions even if they are doing something else. Most instructors realize when someone has a problem point and want you to work on it if you want. Just put him in a heal and work attention instead of doing other things.

One last thing.... if you are in class and the attention is really bad put him in puppy management (take leash with your foot and force him into a down and remain standing on the leash as close to the buckle as possible). Once he settles you can release him and try again.

Don't feel obligated to keep up with the class. You need to get what is important for your dog at this phase of his training accomplished and a good trainer will recognize this. That doesn't mean you make distractions while the others are training though.

Let me know if you have any questions about any of this!
