Puppy Bath

How often do you give your Frenchie a bath?  We bathed Ivy much more frequently when she was a puppy as she would sometimes have accidents or make a bigger mess when she was younger.  We now bring her to the groomer once a month and give her baths as needed (as we don't want her skin to dry out).  One thing I have struggled to find is a good brush/comb for brushing her between baths and grooming appointments.  Have any of you found a good brush that works well to pull out the dead hairs? The one I am using doesn't seem to be doing the job. 

Ivy always thinks she likes baths until she is actually in it... 

Everything is a little pink hued due to the 1950's pink tiled bathroom!
