Smokey gets a bath once a week (unless he gets into mud, then it could be twice a week - or at least several rinse offs).
His nails stay pretty worn down cuz they do a lot of running on cement. But I usually have the vet cut them since the one time I tried I got the quick (Smokey didn't even flinch and he was a BABY! )
He hates having his ears cleaned so I've been thinking about taking him in for that at least ... But the ears seem to get pretty clean when I bathe him.
He hates it when I put like a cotton ball or Q tip in there to clean; he'd rather I just stick my pinkie finger in there and dig around.
