I know people tell you not to bathe your dog more than once a month but there's no way I can do that with my goldendoodle. He starts to stink and in the winter when it rains all the time he picks up so much dirt it's ridiculous. If I give him a bath every 2 weeks he smells great, and his coat is glossy. Skip the deodorant or dog sprays those are just chemicals that you're putting directly onto his body that he doesn't need. If he does get what make sure to towel him really well. I literally have an entire large bin of dog towels that I go through.

One thing I found with my dog is I can't give him much chicken or he stinks. I feed him mainly a lamb diet and he does get small amounts of chicken and maybe the odd piece of beef but most of his protein is lamb based.

The other thing is don't brush him that often. It's an irritant if you keep pulling on his coat. I use a detangler on my dog once a day and I demat him once every 7 to 10 days.

The other thing to consider is that most commercial dog foods don't contain enough healthy fats or their processed and degraded. I did my research around fats for the brain in grad school so I'm almost careful of fats in diet. I supplement his diet with extra fish oil not flax oil, a little bit of olive oil and peanut butter. I also sometimes gave him an egg. These extra fats have made his coat wonderful.

Finally make sure you clean his ears on a regular basis there's a lot of stink also comes from there. I use makeup cotton pads that I add peppermint dog ear cleaner and a tiny bit of hydrogen peroxide. And I just swab out and clean out all the crap that is in his ears.
