The possibility of self-study is very small. Knowledge of pet grooming, medical care, etc. needs professional and systematic training.

At present, there are many training institutions. I suggest you work in a pet shop first. General pet stores will also help employees sign up for training and study.

Even if you have been in the pet industry for several years, you still need to keep learning.

The threshold for opening a pet shop is very low and you can spend money. But you have to consider your business model, your competitive advantage, your main business and so on.
