I have owned pets my entire life, mainly dogs and birds.
I currently own an indian ringneck and pet sit friends and family dogs when they go away. I love dogs and take care of them, take them for walks and most of the time they get to sit in the aircon at night and watch movies with me.
I have a nice sized yard for small and medium sized dogs. Big dogs would do fine overnight but wouldn't be suited long term. My yard is fully enclosed with a fence and pets would also be allowed inside.
