i have had 3 bassett hounds over the last 6 months and all 3 have had a smelly odor to them, i have not consulted with their vet about it yet but are getting them bathed about every 2 to 3 weeks. i was wondering if maybe the odor was isolated to their particular kind of breed being hound?
Maybe it is from there ears or the skin folds. I recommend a vet visit. Good luck, vetcare
