I do a bit of grooming every night. I brush Thor's teeth, clip just one toe nail, brush him, and usually cut a bit of his hair. I don't do a particularly good job on the hair. I want to take him to a groomer again once I get his nose hair fully grown out.
Thor pretty much never gets ear wax, and doesn't need his anal glands expressed. We're both lucky there.
Usually I only bathe him once per month! It's a bit gross, but he hates baths so much, I feel bad doing them more frequently.
