Sausage variety? (3)

Ross

I believe the answer is:

dog

I'm a little stuck... Click here to teach me more about this clue!

This clue could be a double definition.

'sausage' is the first definition.
(I know that dog is a type of sausage)

'variety?' is the second definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.

Can you help me to learn more?

(Other definitions for dog that I've seen before include "'Every . . . has its day'" , "Cur" , "Domesticated canine" , "Shadow" , "Hound" .)

I've seen this clue in the Evening Standard.
