In January, we had to put down our Rotty due to cancer. She was part of "Sadie's pack", my German Shepherd. Sadie seemed fine for a while, though she had adopted me as her "special person" instead of anyone else in the house. That was four months ago...now Sadie seems to be showing signs of stress...she is 10 years old and all of a sudden she is "marking" my side of the bed, is hysterical when I leave the house without her, even when the other family members are home, is never farther than a few feet away from me at all times, when we are in the house, and always keeps her eye on me. She even tosses her beds around the room and balls up the bathroom carpet when she is left alone, even for a couple of hours...and it seems to be getting worse. I have been spending more time with her, and taking her with me as much as I can, along with taking her for daily walks, just the two of us. She has never been an only dog before, and I know that this is new to her, but I would like to make her feel safe and secure, to ease her stress! But I am at a loss as how to go about it. She just visited the vet, so she has a clean bill of health. Is it possible to start mourning the loss of a pack member four months after the fact? Any ideas as to how to handle this would be appreciated!
