That's pretty uncalled for, don't you think? I don't know Zuzupetalz's situation, but as for myself:
I love dogs and I can't wait to adopt one from a rescue. However, my husband and I are at work all day and the dog would be by itself for long periods of time. Also, we wouldn't be able to afford large vet bills if something were to happen to it (sickness, injury, etc.) That, in my opinion, is WAY more selfish than not owning a dog.
