There's no denying hounds can have a distinctive odour, but in their defence have smelt far worse in other breeds & like any dog/hound is down to management & input.
I've known two Otter hounds in recent years & both fabulous gentle boys, but not really in ideal circumstances, bought with little thought & no research. One, very over weight, with front problems that required surgery to one leg & by the tine we knew him, limped, was sluggish & inactive. The second, always imagined was a whim purchase, left alone for long periods most days, had little if any input or company, & ate everything from school uniforms (serves them right for leaving them lying around), to skirting boards, walls, window sills & anything in between.
Personally love hounds they are not easy, wouldn't want them any other way, but wouldn't want to own one I couldn't let off lead, but that's down to training & constantly being aware to what's going on.
Otter hounds are 'large', need lots of floor space, our two bassets used to curl up easily between the outstretched legs of our friends hound.
We had two hounds, both could suffer vocal separation anxiety depending on the circumstances, the elder was the worst & when he bayed, it was a sound you couldn't ignore, deep & bassy, & heard a long distance away.
