Research is the key to everything. You can find almost everything you need on the internet nowadays. In this case, you there is what we call shih poo guide. What is this? Well, it is a guide on how to take good care of your dog. However, I think that the most important lesson that this can give you is to know your dog well and their needs.
What do I need to know?
What is their usual behavior? What would be a good diet of them and what would be a good environment for them? These are the most basic things that you need to learn about your dog. For this kind of breed, they have a more energetic and playful behavior. They do like to bark a lot and they enjoy cuddling. I would highly recommend to train them on how to be silent at times. For their diet, it is highly recommended to feed them dry dog food. I was able to read an explanation that this is because of their mixed nature. It is to protect their teeth. For the environment, they can survive in pretty much any environment but you may need to monitor them because they tend to heat up from time to time. This is because they do have a lot of hair and it has a tendency to feel hot.
