Beth, I'm sorry for both you and Nala for the loss of Branwen. Dogs grieve too, which can be expressed in some puzzling ways. I'm quite inclined to think the poor old girl is lonely and misses her buddy terribly, and therefore misses you even more when you are not there.

Despite the challenges it my pose, please consider getting Nala a pal of some kind. It worked for our 'Cuda dog after the loss of Yogi, helped him become and excellent dog for our family.

As you think on that, I really liked the idea of providing something to keep Nala busy in the house. I used to hide treats around the house for my border collies - in toys, under toys, behind the furniture - anywhere they were allowed to be. It takes a few minutes to set up, but I think they really enjoyed it. Be sure to use really small treats if you're going to put out a lot, though....wouldn't want Nala to gain too much weight (like mine did!).

Sending butterflies to you both to help you sort this out in a very happy way!

Hugs,
~T~
