I don't think it's abuse, but I don't think it ever entirely fair.

First off, I am not saying I wouldn't do it. I work part-time right now, go to college classes and I have a very active dog. I live with my parents and my mom doesn't work so she is home with him most of the time. My dad is only home on weekends and nights, he works full-time. But anyway, someone is USUALLY home with Mikey. But sometimes not, he is young and he can hold his bladder very very well. He is such a good boy when we're not home, but that's not to say he likes it.

It's not abuse, and it is definitely situational as to whether its truly fair or not. Mikey is the most social, lovable, playful dog I have ever met. He seriously attaches himself to your hip, he is what you'd call a VELCRO dog. His first owners, loved him to bits, they spoiled him. The women we got Mikey from made the best decision to find him a new home because it wasn't fair to keep him in his crate all day, she'd let him out at night when she got home, and then it'd be back in his crate for bed a few hours later. She owns a car dealership so she was very busy. Mikey was a gift from her kids. They LOVED him. But it just wasn't fair, and they realized that.

In a situation, you need to realize whats fair for an animal and whats not. If you work full-time and have off nights and weekends or even some weekdays, yeah sure you could have a dog. Not a puppy, but it's not abuse. Some dogs actually like it. People have to make a living too. But if you work full time and have weekends off or whatever and you go out and leave the dog home alone ALL weekend, you have to see, well too a certain point that is just NOT fair.

Good luck in whatever decision you make.
