Ever notice how many 2 yr. old dogs just love to run? Sometimes, Yoko takes off on her outrun at neck breaking speeds. There will come a time (maybe) that she will need to "think" a little before take off. It's just SO much fun to run. :0) Yoko is a lot like Jet. Soft, easy dogs that just want to do everything right.
Kilt has been anything BUT an easy, soft dog. Kilt needed and still does at times what I call "grinding down" on. I believe I took that term from an article Candy Kennedy wrote. It was a good article. If you can find it, read it. Instead of just taking off, I sometimes have to stop her immediately and maybe a few more times in order to get her to think....not just take off. I need her to be "mindful" of what she is doing.
Every dog matures at a different rate and I certainly wouldn't grind down on a soft or novice dog. I have several dogs in mind right now that would benefit from a "grinding." LOL I was never hard enough or knew what I was doing with Kilt. I had been spoiled by Jet. Kilt turns 6 yrs. old next month and she is really trying to think now.
Gotta love a thinking dog.
