It's up to you - whichever you think best suits your thread However you might want to keep in mind the following: You might want to use the health/training/behaviour/grooming or activity specific categories (rather than the more general 'questions' or 'discussions' categories) if your thread is about one of those topics - because you may find that some members keep an eye out specifically for those categories and so your thread might have a better chance of getting noticed. We have made the colours for the non-general categories, such as health, behaviour etc more prominent - to help them stand out. This is because most threads will probably be general chat or discussions, and having more prominent colours will help these important categories stand out.
