"Look at that" is something you may have heard of if you're interested in clicker training and positive methods of training. It's in the book Control Unleashed, by Leslie McDevitt. It's sort of what I've done when working with Elka in respect to other dogs. At absolute perfection, I want her to just be able to ignore other dogs. At worst, I want her to be able to be calm around them. Lofty goals, right? Shoot for the stars!
So, I mentioned how we'd been counterconditioning when it came to dogs barking in yards. Look at that is similar. The idea is that you keep your dog under threshold, but within sight of the thing that makes them apprehensive/bonkers/afraid/hyper focused, whatever. Have lots of tasty treats! Say "Look at that" and indicate the Thing to your dog. When your dog looks at the Thing and stays calm, click and treat. Gradually, you'll be able to be closer to whatever the Thing is, as you've reinforced all of that lovely calm behavior. Here's another very good description of it, if I seem to muddled.
So, if your dog has a great need to focus on things that seem to make her anxious (bicycles, skateboards, other dogs, people in hats), consider playing Look at that! It seems like a strange thing, really, encouraging the dog to look at a thing when looking at that thing makes her nervous, but I think the key is that it allows the dog to realize that the Thing is a non issue, and that remaining calm and perhaps focused on your is much more rewarding.
I don't use the words "Look at that" with Elka (mostly because I forgot until I was more versed in what I thought it was), but I will say "Do you see?" Granted, I say a lot of things to Elka, such as "on by", "keep walking", and "that's not your problem", depending on proximity and behavior of the other dogs.
What with all of the encounters we've been having, reinforcing Elka's calmness around other dogs and focus on me is an invaluable thing. It helps in other venues; a squirrel ran across the sidewalk in front of us on a walk today and Elka's head came up, she took a step, and looked at me.
We had a great impromptu session of "look at that" today on the way home from our walk. We'd already gotten the yayas out at the park and were in the home stretch when a woman with a young golden retriever looking dog came out of a house across the street and proceeded up the sidewalk. From across the street, and down the block a little, Elka was able to look at the dog, and look at me, calmly and with no other excitement than getting the treat into her mouth. We walked in tandem for a block or so before Elka and I made the final turn to head home.
