First of all, the average amateur's standards are not nearly as high as an experienced pro. We can focus on our dogs all day long. Now you might think that can be to our advantage, but how much time does your dog spend where the standards are a little looser? Truthfully? A pro's dogs get out to air, trained and maybe a little run but they are either closely supervised or confined. The amateur dog is less supervised and OB is not 24/7.
Pro's that take in a new dog to train rarely find OB where they want it. For example.....one of the rules for starting force fetch is to have solid OB skills. What does "solid" mean? Pretty good on a leash is not enough.
If you can walk to the holding blind, sit your dog and leave.......that's a start. If after you leave the blind, you can ask your dog to heel and sit. That's better. If on the way to the line, you can take a step back and your dog responds with a backward heel.......that's almost there. If you change your pace going to the line and the dog does, too. Good for you! If you get to the line together and your dog sits beside you without a command. That's the standard.
But if you can casually make it to the line (both you and the dog) while not doing any of the "dances" I just described and look cool doing it........you are no longer a "grasshopper".
