Trixie and Dixie

These 2 little sweeties were placed under a trash can in a woman’s yard in all this heat! It was so very fortunate that she went out and heard the faint sounds of cries coming from under her trash can. They are appx 7 weeks old, they have had their first set of shots and worming. Trixie only weighs a little over 4 lbs and Dixie around 6 lbs. We are unsure of their breed mix.. possibly lab?
