Ryan Reynolds’s dog is having a lively week!

The actor’s multi-breed pooch, Baxter, has been spending quality time with a new lady – one Blake Lively – who sent tongues wagging when she stepped out with beau Reynolds this weekend in New York City.

And now tails are wagging, as the Gossip Girl star was spotted taking Baxter for a brisk walk during a break in filming her show Tuesday in Manhattan.

Lively held her teacup Maltipoo, Penny, in her arms and kept her wrapped in a fuzzy brown blanket as a leashed Baxter pounded the pavement.

Later that night, Lively and Baxter left the Gossip Girl set together, and the following morning, headed off to another day of work.
