I've always wanted to try agility with my dog, but she's pretty dominant - not nasty, she wants to basically push other dogs around, not hurt them (though this is obviously unacceptable to some other dogs, which leads to WWIII) - so I'm hesitant to take her to agility classes. Therefore, I made us a little practice run in the yard - a ladder on its side, a hoe across two birdbath bases, a piece of wood across two chairs, etc. She's picked up the idea of "over" though she's less enthusiastic than I'd hoped. She will, however, do much for a liver treat. And we're working on 'through' with a tarp tunnel between two chairs. Any other suggestions for rough approximations of agility obstacles that don't require hammer, nails or any skill at assembly? Any suggestions welcome, actually.
