Is a greyhound dog called a whimper?

Answer 1

I've never heard that in all my years at dog shows and around purebred dogs.

A Greyhound is a separate breed from a Whippet, which may be where the confusion comes in.

There are 3 breeds that look like a Greyhound in but in different sizes

Greyhound (largest)

Whippet

Italian Greyhound (smallest)

AKC comments on the breeds:

"Both the Whippet and the Italian Greyhound look like miniature Greyhounds, with sleek, slender bodies and narrow heads. Both breeds are from the same “family” of dogs, known as sighthounds, and they likely share a common ancestor.

The breed we know as the Italian Greyhound originated in the Middle Ages, when Italians began importing small sighthounds en masse. It is unclear whether the dogs were used for hunting small game or for companionship. The Whippet, in contrast, was definitely a hunting dog — specifically for hunting hare in open fields. Their development began in 18th-century England, when they were known as “the poor man's Greyhound.”

The main difference between the two breeds is size: the Whippet is 18-to-22 inches tall at the shoulder, while the Italian Greyhound is only 13-to-15 inches tall."
