I am having the same problem with my Michi who is almost 5 1/2 months old. He used to be the sweetest thing but the past 2 weeks he has changed so much. He bites like crazy and growls. He used to sleep so good in his crate all night from 9 pm to 5 am. Now he won't sleep in it and wakes up lot during the night. I don't know why the sudden change.... |
