As far as the feistiness a couple things come to mind- 1. She may be biting more due to teething and 2. The Yorkshire Terrier Club of America recommends that puppies not be taken away from their moms before 12 weeks of age. That is partially due to the puppies being taught social skills by mom and litter mates during that time. The social skills would include appropriate play behaviors such is when is feistiness enough and gentler play. 3. It could be the pups age. When Ruby was a young pup she had two speeds..all out and sleep!! Good luck with the new pup. Post pics when you get this site figured out!!!
