Porsche, my 13 year old Yorkie, remains behind after having Bentley as her "brother" for over 10 years. She never cuddled him, nor him her. Yet, now that he has passed, she is showing some of the same signs of dementia that he had shown before he died. The most significant is that she gets us up in the middle of the night to come downstairs to sleep in her own bed. Since she sleeps with us, she whines or cries until one of us gets up to take her downstairs. Do you think this is grief or just being spoiled? My husband is the one coming downstairs with her. He is having a very hard time sleeping. What do you think?
