In my case, my hounds are fed a rotation of high-quality, grain-free foods. Yet, they still have a slight smell to them. It isn't an awful smell, or overwhelming, but they do have a slight odor. I think I notice it more with the hounds because I had Sasha first, and she never smelled at all - unless she rolls in something (yuck!).I don't have a hound nor have I had really any extensive experience with hounds, but could the smell be due to food? I know dogs that are fed lower quality food generally have a more 'doggy' smell to them versus dogs who are fed a higher quality food. Are these hounds getting fed different foods than your non-hound dogs?
The yeast infections do smell awful. Heather had several yeast ear infections before we discovered her food allergies. My hounds ears are cleaned every week, and still, if they aren't bathed regularly, they do have a slight smell.Let me suggest something to consider...Some of these posts list dogs with droopy ears. Dogs with droopy ears have a higher chance of having a yeast infection (yeasty smell), bacterial infection (pungent smell), or possibly sinus infection (not exclusive to droopy ears, but may smell moldy). A mild infection may have a mild smell, but head shaking and ear scratching (or nose scratching for allergies) may indicate the need for closer examination.
I bring this up b/c my sister adopted a senior standard poodle. She told me that "poodles smell." I came by and recognized the smell, and the owner had sold the dog with a bad yeast infection in his ears. A trip to the Vet, 2 weeks of drops, a couple of months of maintenance ear cleaning, ... and poodles no longer smell...
Ever hugged a bloodhound?I have heard people say this before, I think it a myth.
My long haired dachshund never had a smell that's different from other dogs. Actuelly he normally does not stink at all unless he rolled in something haha. We Bathe him, clean his ears and teeth. Keeping their ears clean is very important, in both hounds and other dog groups. Many hounds or dogs in general can generate a smell from unclean ears and have bad breath from teeth that are never cared for.
As for other types of hounds, I have never noticed a bad smell on them either. I have been around plenty of Beagles, basset hounds, and some grey hounds.
