Removed the following from article, as it's not true--all dogs can scent in the air and after a rain. See article for better description.

Bloodhounds, unlike many breeds of dog, have the ability to follow a scent in the air. Most breeds follow the scent marks on the ground or on nearby objects. This is why many dogs will lose a scent after rain, or if it crosses water. The Bloodhound's nose is so sensitive, it is able to pick up the much more diffuse scent from the air.

"It is believed that..."

In the "Scenting Ability" section, the last sentence uses a common weasel term: "It is believed that pendulous ears and moist, pendulous lips...". I know this is a minor complaint, and the knowledge is less than arcane, but is there a source we can cite? – ClockworkSoul 15:49, 25 Feb 2005 (UTC)

You're right. I probably wrote that myself (for shame) and I'll see whether I can backtrack to where I got the info. Elf | Talk 20:41, 25 Feb 2005 (UTC)
