Nice entry! I love how colorful and playful this one is. I kinda like how the music (and dogs?) speed up as time ticks down more also, even though it makes it a bit more stressful. I think an infinite time mode would be very cool.
The UI that you have made for this is quite nice also.
The main constructive feedback I have is try to have the dogs not crowd each other so much because everything starts jittering then and it's hard to grab a hold of what they want you to at that point.
