Her weaves are looking good, I wouldn't worry that much about speed right now. Once she has the entrances down and the footing the speed will come. When the time comes I've found that gates help a lot in the speed aspect of weaves
as it's a no fail concept and it gives the dog a chance to really build their confidence, it also helps to have something the really like to work for at the end to toss out for them. Like I said though I would work more on the footing and entrances like you currently are.

I've just started working entrances and weaves with Kiz who knows how long that will take to teach him hopefully not to long. He seems to be able to pick up physical activities better then the boring stationary ones. Guess we'll see.
