How much are mad dogs?

The term "mad dog" is not a recognized type of dog breed or a specific product, so there's no standard price for it.

It's possible you are referring to:

* A slang term: "Mad dog" can be slang for a person who is aggressive or dangerous, but this wouldn't have a price.

* A specific brand: There may be a product or brand that uses the term "mad dog," but without more context, it's impossible to determine a price.

Please provide more context or details about what you're looking for so I can give you a helpful answer.
