Hey Nerdy,
Is the odour more noticeable during the winter and spring seasons or during the times when your climate is at it's most humid or windy? Our B has that distinct wet dog smell after baths or when out in the rain, however the smell does not stay. He does have that funky corn chip smell in his paws when it's dry outside but that goes away too as Kairoe cleans himself like a champ when he's not sleeping.
One thing that does come into mind, is when he accidentally steps in his urine or he accidently sprays himself - usually happens when he pees against the wind! When that happens he does smell horrible and it will linger throughout the apt. and on him until we wash it out.
I think if you rub something on his coat - that is pet friendly, it may get him to want to get the scent off and perhaps train him to groom himself more frequently. - we just don't know what will work that smells nice to a human but wanting a dog to lick it off…
Cheers!
