I keep trying to fix my wolf

Her name is Aysa ID 2801040

I kept making an request with help me but i can never reply on it thats why i do it like this

I looked up how to get my wolf better on help

this is what there is standing:

My wolf is injured. How do I heal it? If your wolf is injured there will be a red cross next to them on your Den page. It will also say on their Wolf page that they are injured, and it will list the color potion you need to heal it. Go to Realm > Barter > Search and search the Market Dens for the potion. After you purchase it, you can use it either on the Wolf Page, or on your Den Page.

I do what there is standing but i can not find the color potion they talk about. Can somebody please help me how i can heal my wolf? Thanks
