Honestly, I bathe Daisy whenever she starts "smelling like a dog". You know that smell, when she smells like everything else in the house does. Usually, it's once every 2-3 weeks. It's usually on a Saturday because that's when I'm the most free, but it doesn't matter. Whenever it smells of 'DOG' when she walks into the room, I take her upstairs and draw her a bath. :P

I use 3 different shampoos. Two of them are prescriptions from the vets that are medicated, and one is an over the counter shampoo.

The one I use for her body is called Dermal-Soothe. It's an anti-itch shampoo that's supposed to soothe the entire body. I always do a quick lather of this on her feet and such. The other one is called ChlorhexiDerm (the active ingredient is Chlorhexidine Gluconate). I apply this to her paws, between her toes, on her privates, and on her belly. I let both shampoos sit for about 10 minutes total. Each foot has to stay out of the water for a good 2-3 minutes. The over the counter shampoo is changes. Just anything that is tear-free (as the two medicated ones are not allowed near her face) and that is a good brand, imo. I can't remember the brand I'm using right now, but it smells WONDERFUL.
