The American Kennel Club (AKC) breed standards for the Vizsla states that the coat should be short, smooth, dense, and close-lying, without a woolly undercoat. The Vizsla is not suited to being kept outside since, unlike most other breeds, it does not have an undercoat. They are self-cleaning dogs and rarely need to be bathed, if ever. They have little noticeable 'dog smell' detectable by humans. After several forays into lakes and streams they will develop an aroma that is a weaker version of the 'wet dog' smell. A quick bath and this odor will vanish. Various breeds are often mistaken for Vizslas and vice versa are commonly mistaken for other breeds. Redbone Coonhounds, Weimaraners and Rhodesian Ridgebacks are most commonly mixed up. The body structure of a Vizsla is very similar in appearance to a Weimaraner and a Redbone Coonhound, though the Vizsla is typically leaner with a more defined musculature. However, Weimaraners and Rhodesian Ridgebacks are larger than Vizslas.
