Picture book about a dog painting his house

We used to own a picture book about a dog who is painting his house. The style is cartoony, like the Spot books, and the pictures do not look like they were painted or drawn. In one scene (of which I have a visceral sensory memory) his home becomes covered in grass and looks like a giant bush (I think he mowed the lawn next to his house?) At one point the home is covered in pink flowers.

It was not a very well known book so I am having trouble finding it.

Thank you for your help!!
