4 yrs ago I bought my wife her first dog, ever. A pup that is half corgi, half mini australian shepherd. She's leaner than a true corgi, with lots of grit. Once at the petco store a friendly german shepherd got too close for our dog's comfort. She stood her ground, and looking up at this giant of a dog, she bared her teeth and uttered a menacing low growl (for a corgi). The owners of the GS busted out laughing, but the GS backed away.
