Part two ... my messag was too long!
You can then start making it more difficult, and becoming quieter about it.
After about two weeks I took off my shoes and tiptoed in sock feet to my first hard hiding spot. In the bathtub behind the shower curtain. Took Ky about 2 solid minutes of being IN the bathroom to find me. And trust me, it was REALLY hard to breathe quietly and not crack up laughing ... I could see her through the shower curtain, but she couldn't see me.
If you have more than one person in the household, teach your dog their names ... and then have them hide and say go find so and so ...
If you do sport training with your dog, I've been told you aren't supposed to play with them in the house (one of the reasons, I chose not to do sport training!) You are only supposed to play with them outside, and I was also told that they weren't supposed to play with other people.
