Though some Otterhounds do have a fair amount of coat they do not shed
a great deal. Expect to brush an OH on a weekly basis to keep the coat
from matting. Otterhounds have big hairy feet that are attracted to
mud. Most OHs aren't slobbery dogs, but they've got beards and long
hairy ears that get into their water bowls, food dishes, etc., and
then act as transport mechanisms to spread water, food, etc. around.
Though an Otterhound's undercoat should be somewhat oily, they don't
seem to develop the strong "doggy" odor that some oily coated dogs do.
Unless you are actively showing the dog, frequent baths should not be
necessary. You will probably need to clean ears on a regular basis.
