Dave and JC -ain't that the truth - forgetting that is
Deb's email and screen name since almost the beginning of email for her is "IForget" 
Dave that picture was taking 5 days before we lost her to lung cancer. Would never know she was suffering looking at the pic though.
And Molly, who was always a bundle of happiness, has had that sad look now for 3 months (2nd pic). The two were inseparable, even though they tried to take each other out early on.
I'm firmly convinced that dogs grieve...when I had the Greyhound rescue (Shug) he and my Austrailian Terrier, Nell, were big buddies. When she died, he got a mysterious illness and I ended up losing him 3 months later. A team of vets never found out exactly what was wrong with him, and we tried everything short of exploratory surgery. I think a broken heart played a part in it...
If anyone here lives in an area of the country where they race Greyhounds, I would strongly encourage you to adopt from the track...many of the dogs retire from racing at about 4 years old, and some of them just don't care for racing, so you can get one about 2 years old...all the shots, spayed/neutered, teeth cleaned, special collar. People think they would be "hyper" because of what they are bred to do, but nothing could be further from the truth. They are probably the sweetest, most intelligent, and sensitive breeds I've ever been around...plus, they are absolute couch potatoes. Clean like a cat too. Very well behaved...the local track does a fantastic job of screening the dogs based on personality traits, so they fit in homes either alone, with other dogs, or even with cats. Shug would fly around out in the backyard for about 3 minutes each day, then spend the remainder of the day literally on the couch. For a large breed, they are very graceful and know where their body is in space, so don't knock things off tables, etc. Very well mannered. Crate trained as well.
