I’ve taken care of my 2 shih Tzus for around 4 years taking on the responsibility once I was more grown up , they’re our family dogs and 3 years ago we welcomed 2 labradors into the household! And between me and my sisters we learned everything from looking after puppies where we trained them to use outdoor for toilet , small tricks such as sit , wait , stay , paw and to the early rebellious youngster stages until up to now where they’re fairly trained go on daily walks and exercise and a nightly routine to settle down for bed.
