grooming
You don't need to get him groomed as long as his coat stays a length you can manage. Along with the brush use a metal comb- a grayhound comb they are called- it will show you where there are any mats or tangles to brush out. The comb is every bit as important as a brush. If he gets eye boogers wet a cotton ball and take them off with a fine comb, like a flea comb. If you don't remove them they can make sores under his eyes, if you pick them off when they are dry you can tear the skin. Depending on how much hair he has in his ears, some dogs need to have the hair plucked and some don't. There are two sides to the ear plucking thing, I'm somewhere in the middle. You shouldn't pull are the hair so it makes his ears sore but there has to be enough out to be able to keep them wiped out. Get some ear cleaner and wipe them out.
Washing him once a week is probably a little too much, you'll dry out his skin. Stay away from human shampoos and anything by Hartz Mountain. There are lots of good shampoos out there, you might have to try a couple to find one you like. Make sure you check to see if it's concentrated and needs to be diluted. Bio groom used to make a really great herbal shampoo, the tea tree shampoos are good if you like the smell. People seem to think oatmeal shampoos are good for skin problems, but I think they are too drying if you use them all the time.
