Nina Ottosson Interactive Games?

[Allyson, Peri & Taquito]

I searched some of the other forums on different interactive games. It looks like the Hide-a-Squirrel is a hit among many of you. What about the interactive games by Nina Ottosson? Our trainer recommends them...they make the pup work for a treat. They are somewhat expensive, so I wanted to see if any of you have had success with them. Any suggestions are greatly appreciated.
I can tell that Peri is always thinking. It is amazing how much exercise she gets, but still doesn't tire at all! However, when we train her, she gets zonked. I think using her brain makes her more tired than using her legs :) That is why I am interested in the interactive games.

No kidding - Riley is a lucky boy. Thanks for all of you input Ellen. I think I will start with the Brick one and see how Peri likes it. Many thanks!!!

[Leslie and Halas]

I bought Halas the Dog Fighter. He's doing great with it, as long as it's just the normal, smaller pegs. If I put the larger pegs in, he's not sure what to do with them. He just pushes on the small ones until they turn sideways and fall out. But the bigger ones won't do that. He has to grab those with his mouth and pull them straight up, and he hasn't figured that out yet. I just posted a video on our page if you want to check it out. He figured it out pretty quickly, but it's fun to watch him progress and get faster. I've been using training treats in it, but tonight I put his kibble in it when I took the video. So he got all of the pegs out, but left the kibble until the end. Then he ate all of the kibble pieces at once. It was supposed to be a birthday present (Sept. 1), but, of course, I couldn't wait that long to give it to him.
