My boys would do the same thing when they were puppies. Play for 15-20mins, then be out cold for a couple hours. Actually they are 10 months old now and when I take them for a nice 45 min walk, or bring them to my moms to run around for a couple hours, when they get home they pretty much fall right asleep for the night. I don't think it takes much for a yorkie to get worn out! |
