How to stop Acrobat Reader Icons appearing in dock every time I open a pdf?

Just to add 😎

Permanently change the app used to open all files of a particular type

1. On your Mac, click the Finder icon  in the Dock to open a Finder window.
2. Select a file, then choose File > Get Info.
3. You can also Control-click the file, then choose Get Info.
4. In the Info window, click the arrow  next to “Open with.”
5. Click the pop-up menu, choose an app, then click Change All.
6. Note: Don’t click Change All if you only want the specific file you selected to open with that app.

Open the PDF with a different app. Preview perhaps.
