Something about the crinkle of plastic is what gets Nyx going, she loves it! One of my fondest memories of her puppyhood was when I picked up 2 plastic milk jugs for the first time and rubbed them against each other. Nyx looked a bit shocked at the sound...for a second, then charged right back to attack them! She's an oddball, anything noisy gets her excited!
She is also a master thief. I can't leave anything in the wheelbarrow after doing yard work or she'll steal in all and spread it all over the yard. Even the fire pit is not safe without a cover, she steals all the partially burnt logs out and spreads them all around! And the funniest part of this is how gall dern happy she is about doing it!
Recycling items have been her favorite toys her whole life. Conventional dog toys just get consumed! And they mostly squeak, which is good, but of the numerous toys she's had that did, once ripped apart I've only found one squeaker LOL!
