Query: too tall, wheels get choked with fur

My 50 percentile 6 month old couldn't touch the ground in the lowest setting. Since we had bought this used, and couldn't return it, I took my dremel and cut some new notches. That worked great. The wheels were ok on the carpet and the tile. They aren't super smooth, but how fast do you want your baby scooting around the house? The biggest problem is that we have a dog, and the dog fur clogs the wheels and there is no way to clean the wheels out. I finally found a caster wheel supplier that had small enough wheels that fit, but it took 2 weeks to ship and the wheels cost more than I paid for the walker ($20). If you have pets, look for a walker with wheels that you can get the fur out of the axle. I didn't see any at babies R us or walmart though, so good luck.
