Why was the standard size of the Dalmatian consciously developed to be under 23 inches tall during their coaching period?
Answer
So they could comfortably trot under the wagon's axles or between the wheelers and leaders
The necessity of running beneath hitches directly influenced the breed standard; breeders preferred dogs under 23 inches tall so they could fit comfortably under the carriage axles or maneuver between the lead and wheel horses.
