I am so sorry to hear about your loss. I have a cat that is ten years old, and after all that time, they really seem like part of your famiy. My mother-in-law's dog passed away several years ago and their cat who was very close to the dog, really freaked out. She went through a weird depression. They even had to put her on a kitty form of Prozac for awhile. I hope you are able to show your other dog some extra attention for awhile, you could probably both use it.

Sending hugs and happy thoughts your way....
