Wat d’Lëtzebuerger schonns ëmmer woussten, huet elo eng wëssenschaftlech Etüde ënnermauert. Dat geet op mannst aus engem rezenten Artikel vun amerikanesche Fuerscher, deen am “Journal of Zoology” publizéiert gouf, ervir:
We tested the hypothesis that urine marking is a dishonest signal in male dogs. We examined whether raised-leg angle is a proxy for urine mark height and whether small dogs exhibit larger raised-leg angles than large dogs. We videotaped urinations of male dogs and measured height of urine marks and degree of raised-leg angles. We found significant positive relationships between both raised-leg angle and height of urine mark and body size and height of urine mark; raised-leg angle was a stronger predictor than body size. We found a significant negative relationship between body size and average raised-leg angle. Our findings support raised-leg angle as a proxy for urine mark height and provide evidence that scent marking can be dishonest. Assuming body size is a proxy for competitive ability, small male dogs may place urine marks higher, relative to their own body size, than larger male dogs to exaggerate competitive ability.
