This was a charming, light-hearted game. Can't help fall in love with a game about dogs.
I respect the focus on fun with the dialogue and content, emphasising the charm of a good boy. Although it's readable at a large resolution, it can be a little hard to focus with the dog blending into the background since it's all black and white. I would increase the width of its white outline to make it stand out more. The use of background assets is a little chaotic too with inorganic placement and lack of consistency in pixel-line widths.
Good job though for a solo dev!
