What would be the religion of my dog?

I think to be Muslim you have to say that you believe Mohammad is the one tru way to god (I think...) If your dog tried to say that it would just sound like arf's- I think he's an arfertarianist. I have two dogs and this is what religion they are. I'm Christian, but they believe in Arf. It's ok, though- all dogs go to heaven, so it really doesn't matter.
