When did you start liking your first high energy dog?

Got a 9 month old rescue puppy last month. Rescue had her listed as a lab mix but she is definitely a mix of several working breeds.

My previous dog was a chihuahua terrier mix. I remember him being crazy during his younger years, but more recently I remember him being a lazy old man.

I wanted a more energetic dog for long walks, hikes, dog parks, etc. But now I have a crazy, unstoppable, nap-fighting landshark. Is this my life or is this partly the puppy stages?
