yorkie mama,
I did not see the age of your yorkie. Mine is only 12 weeks and loves to play, but she just plays in short spurts - she plays hard for about 30 minutes, then it is nap time again. I think some dogs just would rather cuddle. If you concerned though, a simple blood test at the vet can at least check her "numbers" and let you know if everything is normal. Then you won't have to worry. Good luck! Lucky's mom |
