Japanese Clifford?

A long time ago I remember watching an anime about a dog.. his owner was a girl, and the dog was extremely jealous of this guy that the girl liked... that's about all I remember. << >> Yeah. I'm not exactly sure how many dog-animes there are, and was wondering if any of you know what I'm talking about.

I can only think of Hamtaro but that was about hamsters and not dogs.
