* Greyhounds are built for speed and have been bred specifically for racing. They can reach speeds of up to 45 mph in short bursts.
* Labradoodles are a cross between a Labrador Retriever and a Poodle, and while they are athletic dogs, they are not known for their speed. They are more suited to activities like swimming, retrieving, and playing fetch.
While a labradoodle might be faster than some other breeds, they will not be able to match the speed of a greyhound.
