Bailey nearly died to find us. she was in the middle of the road in a very rural area, my wife almost ran her over. After checking with the only two house in the area, my wife decided that she was dumped there and needed to join our family.
We believe she is either a pit or a mastiff. Judging by her size (5lbs.), her teeth, and that her bellybutton is still healing, we think she's about 5 weeks old. The vet agrees, and says that other than a slight heart murmur, she's a pretty healthy girl.
