This dog clearly loves being part of a dog pack, valuing the security and sense of belonging that only a pack can provide.
I’m sure she loves running around too.

If I moved somewhere I could bike to work from, I would totally get a dog backpack. But one sized for a corgi.

She looked completely at ease. I think she probably had plenty of practice at this.
And, a corgi pack would provide a great workout the human as well ;-]!
