My family’s had a dog for 7 years, who has food aggression issues and doesn’t do well with other people. I have helped teach and train her many tricks; she learned to ring a bell when she had to go potty. I have pet sat several different times by hanging out and taking out dogs or changing cat litter, feeding, and making sure they have plenty of water. Have also watched hedgehogs and chickens. I usually stayed with them for company and if the owners requested, I spent the night.
