Aspen is 7 Weeks old, her personality: nips my ankles, very very playful, whines and sometime barks when she wants attention... Could be because she is a puppy but could be one of her mixes? Her mom is a full blooded chocolate lab but can't figure out the dad... She has very broad sholders, think strong neck, about 15 pounds, has orange on her eye brows, white on her neck and chest to her belly, brindle socks with some white on her toes, black body but brownish in the sun, and "born" with a 2 inch tail... Im so confused

She is a pretty big 7 week old pup if she weighs l5 lbs. Can't tell you what she is made up from just by the description. Your vet would be able to give you some idea by looking at her. Just remember to have her vet checked soon, and get her lined up for all of her vaccinations, so she can grow strong and healthy.

I doubt any of the problems you are having are due to her being a mixed breed of any sort.

Puppies do that.. they are high energy, playful and test their boundaries every chance they get.

If you want to absolutely know what breeds your dog are... you can do a DNA test. The test companies claim to be accurate... My own personal experience wasn't that great, but maybe it was the company I went through. Google DNA dog testing... You might be able to figure out what makes your dog tick that way.

A picture might help us give a better guess, but no matter what, it would be a guess.
