Data Collection and Statistics for Experiment?

I was supposed to do an experiment and I came up with the idea of teaching an old dog vs a young dog how to fetch a ball. The thing is now that I think about it I can't think of any statistical tests to run on the data because I was just going to measure the total time it took each dog to learn. So my question is can anyone think of some other way of collecting the data and some statistical tests that I could use with that type of data?
