Exactly what I was thinking - although maybe OP thought their neighbours were going on an exceptionally long holiday? lol

Meh, they could have mostly moved, asked OP to watch dog then done the rest.

You don't necessarily need a moving van, we didn't the last time we moved.

some people r wierd... if they didn't want to b noticed they couldve moved out in the middle of the night

It never said it was an appartment. Just letting you know.

Why would they think of it if no one told them? I'd be pretty damn mad if I was trying to do a favor for someone and then they just took advantage of me like that. What if they don't have the financial means to take care of a dog? What if they just don't want a dog? That doesn't make them a bad person. Even if the neighbors for some reason could not bring the dog to wherever they moved to, I still think it was incredibly selfish of them and in no way is the OP in the wrong here (in my opinion).

don't say y'all

If they couldn't take care of their dog anymore or had to move to a place that doesn't allow pets they should have told the OP instead of just leaving.

Perhaps the moving vans showed up while the OP was at work. Most people actually do move during weekdays, after making settlement on their new home, so I can see how the OP missed these jerks moving. The fact that they were planning to dump their dog on the OP also made it imperative that they moved when the OP wasn't around. These people did not want this dog and were too lazy to take it to the pound themselves. More pets are being dumped now because of the economy. Pets, especially dogs, are expensive and as people are laid off or taking pay cuts, their budgets are strained and the dog becomes an unnecessary mouth to feed. OP, you did not choose to own a dog so don't feel bad if you don't want it. They are expensive, smelly, dirty, pooping, peeing, barking, barfing, humping, slobbering, jumping, chewing messes who trap you into rushing home for their crapping schedule (sorry, I have to leave this wonderful dinner party early so I can go home and walk Fido so he can take a dump). Some people are so desperate for companionship that they put up with this nonsense but you are not obligated to do so. You were stuck with this dog by trickery; you did not choose it. If you can't re-home it, take it to the pound. It will be worse for the dog if it is living in a home where it is unwanted.

Maybe they knew the neighbors were moving and thought they would pick the dog up when they left...

Not cool, man. Not cool.
