It helps to think about brand as a building. Values are foundation; name is a roof. The building under such a unique roof as yours must be bigger than a blog. Thus, a national media about animal rescue and wildlife in Portugal is good one to aim for.
I'd strongly recommend trying finding the end users in Portugal in the following niches:
a) NGOs
b) pet-related biz
c) national media
d) vegan/vegetarian/eco biz
