Hey,
Here's what I think is the best Bloodhound's Fang build in terms of damage.
This serves as a continuation to my early build guide using this weapon :    • Get a Very Strong Build in 30 Minutes...  
I included the location of every main item used in the build for your convenience.

Weapons :
Bloodhound's Fang +10
Clawmark Seal

Talismans :
-Shard of Alexander
-Ritual Sword
-Rotten Winged Insignia
-Lord of Blood's Exultation

Buffs :
-Golden Vow
-Flame Grant me Strength
-Bloodflame blade for anything that bleeds
-Lightning blade for anything that doesn't bleed

Thanks for watching.
