My 11 yr old female Yorkie who is very healthy, up to date on all shots and never missed a scheduled checkup, has over the last couple of months on occasion wakes up in the morning shaking, quivering or whatever, doesn't want to eat and wants to stay under my feet like she's scared to death. Yesterday am she did this and it lasted until about noon then all was well she ate her morning meal and went back to being my little spoiled brat! This morning she did the same thing which is the first time she's ever done this 2 days in a row. She's only done this about 5 times total in the last couple of months!
