We just bought a female cane Corso. We were told she was born on November 1st. We got home and weighed her and she only weighs 6 lbs. Is this normal? She also had a sister who was about the same size as her. Google says she should weigh 20 lbs at 8 weeks. She eats just fine and doesn't appear to be skinny/under weight. Could she be a runt or not fully bred? We love her already regardless just worried about her weight.
