My dog seems to be crippled when she gets out. Like she is almost in there too much. She can barely walk when she gets out. Is that bad. Am I leaving her in there to long. I thought it was a part of training to leave them in there. She doesnt even want to get up and walk when I open it up. What is a decent amount of time they should spend in the cage at 10 weeks old. Thank you once again.
