Less you be tempted to think heavy drug use...nope, just an Energizer Puppy!
This morning I let Denali play with her new puppy, Sage, for a LONG time. The puppy never did "run down." After 2.5 hours I had to crate him, just to give this girl a break! Sage adores his new big sister, and just can't get enough play time. Currently she looks like this and he's upside down, snoring in his crate!
