That could be possible! But since they have bad cardiovascular problems they can’t really run for to long or walk for long distances if not taken care of properly!
there must be a deeply ingrained instinct for dogs to run fast with each other that gets tapped into when a person is riding on a bike/open vehicle alongside them
Guessing you know this because you had a Dane that just lays on the couch all day and never gets to play outside and be a dog, then had a heart attack? Sorry for your loss.
Fast, until a greyhound passes that at 45 mph. What makes a greyhound faster is how they run. It's called a double suspension gait, like a horse or a cheeta. Seeing this Dane run, they are only suspended once in her gait.
