I think the dog part is perfect with the song. It's unexpected, but once you think about it, it's like wow, the dog noises go excellent with the song. As far as verses go, maybe a few more would have been nice, but for just a fill in, it does nicely.

Few questions though, the dog? Was it one of the band member's pet? Was it the same dog that was on Live at Ummagumma?
