This is our dog. We believe she's a mix of blue heeler and dalmatian among other things. In retrospect, that's not a combination I'd recommend. She's been a handful to say the least. We got her from the shelter as a very sick puppy 12 years ago this fall. While the tag on her collar says "Opal" (as in black opals commonly found in Australia), she has many, many names. I have a pet name for her (yes, a pet name for a pet) that I think describes her more accurately than simply Opal.... rottenuselessgoodfornothinghunkofstinkingdogflesh. Say that 5 times fast. She also has the distinction of having jumped off the Look Rock Firetower. We think she was after a squirrel or chipmonk. Apparently they climb trees better than dogs.
