Totally agree, pets can be a very powerful resource to strengthen the identity of a brand. When they are well designed and reflect the values or personality of the company, they become memorable and generate an emotional connection with the public. That connection makes customers not only remember the brand, but also perceive it as closer and more accessible.
Another point in favor is that pets attract attention naturally. In events, fairs or street campaigns, they usually generate curiosity and attract people who could otherwise not be interested in the brand. They can even be a direct interaction point: photos, dynamics or draws with the pet often increase public participation.
