So you're saying that your dogs are alone for most of the day... and most of the night? This isn't the gotcha you think it is.
Wow I’m cruel and dense.
Yes I do think you are behaving in ways which are both of those things, I'm afraid. I'm sorry if this hurts your feelings, but I honestly believe that there is a greater principle at stake:
Having dogs isn't a right. Like most things in life, some people just aren't able to do so - because they live in rented flats for example, or they don't have the income to cover insurance or vet's bills, or because they work outside the home for more than three or four hours at a time. It's really unfair - but it's life.
Some people feel so strongly that they want to live with dogs that they make really big sacrifices in order to do so - change careers so that they can work from home or take their dogs with them, for example. Or move to rural areas where property is cheaper. But lots of decent humans have to come to terms with the fact that they are not, however unfair or sad this might be, in a position to give a dog a home.
The most awful thing to do in this situation is to insist that your right to have a dog trumps the dog's right to have its needs met. To say, 'they'll be fine at home alone', when you can't possibly really know whether or not that is true.
If you did look into it - surely the very barest minimum when we are considering whether we're fit to take responsibility for an animal - you'd discover that we do actually already know, and have done for at least the last 20 years, that dogs need much more than a couple of hours of human companionship in the morning and evening to be happy. That they might seem happy for those brief moments you're with them, but that's partly because of the contrast with the rest of their lives - the bulk of their lives, when they are sad, understimulated, lonely and often scared and stressed.
To charge ahead without looking into this is the mark of someone who is putting their own needs far higher than those of the dog that they will get so much love and affection from. And therefore it's the mark of someone who shouldn't have a dog at all.
As someone said upthread - this is where it's exactly like having children. NOT because dogs are the same as babies - but because both require you to totally orient your life around them, and often to make big sacrifices . And because sometimes, if you're not lucky enough to be in a situation to do so, you can't have them. It's not to do with your rights - it's because you can't offer what the child/dog needs.
