Bob, sorry to hear about Nico. You have my sympathy.
I know what it's like, since I'm on the fourth and fifth bearded collies I've shared my life with. I wish I could say something to help the pain and the big hole in your life that is now there, but I can't. Right now you're surrounded with people, things, and situations that all remind you of Nico. It's a crappy feeling, but it gets less so over time. But there still isn't a day that goes by that I don't think about the canine and human family members I've lost.
Unfortunately, the "deal" between man and canine is that when you get a dog, unless you're very old or very unlucky, you're probably going to outlive and lose him/her. From the dog's perspective, it's a great deal; they hopefully live to what is, for them, a long life to an old age of usually 12-18 years, a great life with a lifelong friend and protector. From man's perspective, it's a great deal while they're alive and around, but the downside is that you have to lose them, and in most cases, it's a loss you'll mourn forever, just like losing any other member of your family that you lived with for years. It does enable us to experience more than one canine companion during our lifetime, so there's a silver lining in that regard, but most of us would rather have that special friend live as long as we do. Too bad that's just not the way the world works. But the way it does work, it's a great life for the dogs, so I'm good with that.
Some people will ask you whether you're going to get another, and do so right now when it's the furthest thing from your mind. Don't get upset; they're just trying to make you feel better. As far as that goes, it may take you a while until the feeling is right, or you may not get another at all. Just don't rush it. When I lost Cosmo (whom some of you met
at NSXPO 2001 in Wisconsin) a couple of years ago, even though I knew I would eventually get another, I didn't want to do that too soon, because I didn't want to think of the new dog as "Cosmo's replacement". So Layla, Cosmo's daughter, was an "only child" for a while. Four months later, it was a matter of sheer luck that I heard about an available puppy, and Casey's been with us ever since then. Sometimes it just happens that way, almost like divine intervention, like when you met Nico.
Below is a photo of Layla and Casey taken this morning, after we spent a couple hours combing them out.
I was going to close with the Rainbow Bridge, which I've read a hundred times and still can't do so without a tear in my eye. But I see Hugh already did so, above.
Gotta love 'em while you got 'em. For those who have canine companions, give yours an extra hug tonight, in memory of Nico.
