The other day I bragged about being fast, well I wasn't always fast. Here is a video of Grayce the Weim training me with a session of sprints when I was younger (make sure you have your volume on).
See Preston, I wasn't always a fast Puggle. And as you can see we are in fact very much alike (I cry too when I can't keep up, to tell them to wait for me!). You just need a good trainer like Grayce :)
