Ability is great, good choice.
I would say, at least for me, since the fang moves are relearnable at all times, we should get another move. Honestly, they all suck. Bash, is there any use at all for after you?
Also, dang it gamefreak, you make a dog Pokemon and have lick as an egg move. I'm voting for lick, just because dog that doesn't know how to lick is not a dog.
Actually, pursuit, lick, and yawn are all pretty adorable dog moves. Endure is kind of like a guard dog thing too. Yup,i vote for those moves to make the most dog like set possible.
