From Manga-Koekje:
ABout a high school senior named Taketo Iwase and a dog named Salsa. As they set off early on to resolve a problem with a criminal that Toshifumi (Taketo's brother) is having, Taketo sees that there is more to the dog (that can communicate in the human language) than meets the eye. Together they solve a number of troubles and also meet other different species (cat girls, dogs, birds, etc).
