My pet is shivering and seems scare.

Question
Hi,
I own miniature Schnazuer and she's coming 10 this yr. She's very close to me and just 2 days ago, she's pooing and peeing on wrong places, and she seem afraid/scared, her tail would be flat down and she would follow whoever is around and wans their companion. Is she feeling insecure? Due to work i wasn't home that often for these past few weeks as i used to. Or she's really getting old and getting senile.

Answer
Something is stressing this dog out.

It most certainly could be because you are suddenly not around as much as you used to be. Dogs, particularly older ones, do NOT like change in their lives. Be sure to give her some quality time when you are around... taking her for some long walks to tire her out, etc.

She could also be experiencing pain of some sort, or hearing sounds that are bothering her. Is there any building going on near you that she can hear? Leave a radio on for her when you leave.
