Hi again Buffymad:
You really are in a quandary, poor thing.
In an ideal world, we could spend every waking hour with our pets, if we wanted to. But that is not the case and, yes, there are times when the vast majority of us has to leave them unattended. That's just life.
It doesn't mean to say that that is a reason for not having a dog, otherwise many thousands in the UK would not have a home. My wife and I have been in the situation where both of us had to work full time, albeit I was a shift worker, and there were occasions where our dogs at the time were without us for several hours now and again. You get around that simply by ensuring that they're exercised as close to your departure as possible, and when you get home. They are very resilient creatures.
I personally would never contemplate leaving mine in a crate. It's akin to imprisonment, although others will disagree, this is my point of view. My reasoning is that I have invited the dog to share my home, not to be locked in a box in it. We once had a cocker spaniel who gouged one side of a door with his claws because we'd left him for a few hours. Pain in the bum? Yes, but we sanded down the door and repainted it.
If we invite a dog into our home we should do so out of love for it and be prepared for the odd "indiscretion". After all, it's only their way of protesting for our "desertion". But by bunging them into a crate is not only barbaric, it's a sure sign that you've no trust or respect for an animal who only wants you to love it.
Incidentally, we've always been able to leave any of our dogs and cats for short periods without finding dead bodies on our return. They actually get to like, sometimes love, one another.
