Merle is a pattern dilution gene. This means that the dogs original coat colour is diluted by the Merle gene in a pattern unique to every dog. For example, Blue Merle is the result of the Merle gene over a black coat while Red Merle is the result of the Merle gene over a chocolate coat. The Merle gene is not physically displayed in coat colours that are too pale for the Merle gene to dilute, this includes; red/tan, gold, cream, sable and fawn.
White cloudy urine in men may be caused by the presence of semen in the urine. This milky colored urine in males commonly occurs after an ejaculation. Cloudy urine may also occur after drinking alcohol. A darkish appearance to the urine may signify a problem with the liver such as cirrhosis or acute viral hepatitis.
If your urine is cloudy, it can mean that you have some phosphate in your urine, which can lead to kidney stones. If your urine is constantly cloudy, it could mean you have an infection. If cloudiness gets worse and you experience burning or urgency, go see a doctor. More: Measure Your Sweat Loss for Optimal Hydration.
