How do you make pet dyes?

[Llorth]

I have my animal taming at 64 (yay for jewelry) and now I want to level it by making pet dyes. I have the dye and the bottles, now what? I double clicked the dyes and targeted the bottle and received the message "You can not dye that".

How do I create pet dyes?

Thanks in advance.

You must use brush (animal trainers sell it) double click brush then select what you want.
