I just don't get the need to bath them so often? My dogs have not had a full bath since the fall.
I do interim grooming myself with dry shampoo and conditioner. They roll in the snow, and I towel them off when they come in....that's almost a bath in itself! I make them look good by brushing and trimming.
I deal with their poop chutes as required, and muddy paws are also addressed with dry shampoo and towel offs.
Neither smell skunky (in fact, both smell like pups still). Believe me, DH would be the first to tell me if one of them was smelling nasty.
If I had to bath the dogs every two weeks, my back would give out and I would probably give up on having dogs!
It's really not a requirement to bath them that often, if you do proper grooming in between.
