I would like to have a dog, but if I'm away at work, I'm worried the dog would be bored and lonely. Cats are okay but dogs would encourage me to step out and exercise more. And it's also a lot of responsibility to make sure the pet is healthy anyway, I'm not ready to make that jump...
I've toyed with the idea of a communal pet, one main owner but they let neighbors play with it and such, but that's a lot of trust needed to do
A communal pet? That may work in a village. Don't get a dog just to take walks, get one when you are ready. I hear some breeds are okay to leave laying around everyday by themselves, wouldn't do it myself.
