How Often Do You Bathe Your Dog?

I bathe my dog about once a month. Sometimes more if she gets really dirty or stinky. But she tends to get dry skin so I try not to bathe her more than once a month. And there is also the fact that she HATES getting a bath so much! I don't know why. You can tell she feels a million times better afterwards because she gets hyper and wants to play and run around all over the place but she hates the actual "getting a bath" part. lol
