We got a puppy at the SPCA.. she was about 6 weeks old and weighed just over 3 lbs. She was a stray with her mom and sibs. The mom looked like a spaniel mutt. One of the pups looked like a jack russell. Everyone assumes she has some chihuahua since we live in California. She is built like an Italian Greyhound. Very long thin legs. Full grown now, she weighs 8 lbs.... so what do you think she is?
