We have a lone puppy too. She was only one in litter to make it. Ginger is 16 weeks old and over 20 pounds. We try and feed her 3 times a day, while she is growing. Her mother is full beagle, we have no idea what was the breed of the father. Her paws suggest she will get to about 60 pounds.

This was Ginger at 6 weeks. I will try and get a more recent picture online soon.
