Blue racing greyhounds are quite rare. Racing dogs are bred for speed and not confirmation or color. Blues come about by inheriting recessive genes from both mother and father. Unfortunately, this often leads to some “odd” health and/or behavioral issues. Although not all blues are “odd” many are and seem to have more than their share of “oddness.” Mulberry is no exception … incontinent, fussy, extremely LOUD, and not always so nice to the other dogs. But, we love her just the same.
