This thread just reminded me both my guys need a bath very badly.... o_O
Berts was getting a bath every week because he would wander under his brother's leg when the boys are outside....

He hasn't done that in a while, so it's been nearly 2 weeks since the last bath. He needs a weekly bath simply because he really doesn't have a guard coat (all puppy fluff) so he picks up and carried around dirt and junk.
Jacks had a bath last month, I think.... o_O He should really be getting baths every three weeks.
In summer if the baths are connected to post-hiking/swimming trips, I will always use a shampoo that takes care of fleas and ticks.
Year round we use cowboy magic. With Berts, I don't care since it's just puppy fluff and will shed out. But Jacks I do use conditioner. I used to buy dog conditioner (cowboy magic again), but now usually keep a tube of conditioner that comes with Loreal hair coloring. And I mainly use it on his mane/feathering. As I'm not using a lot, a single tube lasts me a long time.
