I don't know what N.I. agility is, but I'm just now barely starting to get into agility as well. My boy is larger at 12lbs but I've seen some small yorkies doing agility! I bought AKC Junior equipment from amazon.com, but so far only have weave poles and a "tire" jump. You can also get a pretty cheap set from entirelypets.com (I think it's about $47). But of course the equipment isn't the greatest quality or anything. Also, I know it's possible to make your own with buying PVC poles from a hardware store, or improvising using logs, sticks, benches, trees etc. I'm hoping to take an agility class this summer-excited!
