During the pandemic, my dog became accustomed to having a human around 24x7. I cannot leave my dog for hours at a time without finding that he has thrown a tantrum -- urinating or defecating in places inside the house, or destroying something. Because of this experience, I will likely never have a dog as a pet again. He didn't use to be this needy -- it's the constant presence of humans that made him this anxious when they are away. But until my dog passes, the situation is at a stalemate.
