Chantal Dupuis chose to paint, in oil paint, large-scale wildlife. This medium makes it possible to seek richness in terms of colors in order to shape her hyperrealistic style. She mainly focuses on the facial expressions, emotions and movement of each animal.

Each piece is a different wild animal and the theme is centered around the conservation of these. The scale of the animal and the large format of her works make it possible to put the animal forward in order to confront the public with the current state of these endangered animals. Chantal Dupuis is a Signature member of the Artists for Conservation organization. Each year, she chooses a wildlife rehabilitation center to which she donates 15% of the sale of each piece. In 2023, she chose to support the Holly Haven Wildlife Rescue Centre.
