Fainting or near Fainting. Rapid Heartbeat â Tachycardia. When the heart beats too quickly (usually above 100 beats per minute), the lower chambers, or ventricles, do not have enough time to fill with blood, so they cannot effectively pump blood to the rest of the body.
If a horse has two copies of Gray, all offspring of this horse will be gray. Research indicates that horses with one copy of Gray often retain some of the original pigment while homozygotes tend to progress to almost completely white. Gray is found in many breeds and is the predominant color of the Lippizaner breed. Gray horses have a high incidence of dermal melanomas that are commonly seen around the tail and head. Over 70% of Gray horses older than 15 years will develop melanoma.
