My advice: use cows instead!

I'd consider that as long as I can expand my tiny room to fit such a giant pet :)

Then you would only need one single cow :)

dogs burn energy through running and playing.
It would be inefficient, since you need to feed them tons of food every month. But yes!

I do agree that dogs run a lot. I'd definitely look into getting cats since they are more efficient house warmers :)

Cats do sleep 20 hours a day (more or less..)
I highly recommend them :)

Cat wins. I'd source for one. Wish me luck :)
