Electroretinogram (ERG) flicker photometry was used to examine the photopigment complements of representatives of four genera of Canid: domestic dog (Canis familiaris), Island gray fox (Urocyon littoralis), red fox (Vulpes vulpes), and Arctic fox (Alopex lagopus). These four genera share a common cone pigment complement; each has one cone pigment with peak sensitivity of about 555 nm and a second cone pigment with peak at 430-435 nm. These pigment measurements accord well with the conclusions of an earlier investigation of color vision in the dog, and this fact allows some predictions about color vision in the wild canids. An additional set of measurements place the peak of the dog rod pigment at about 508 nm.
视网膜电图（ERG）闪烁光度法被用于检测犬科四个属的代表动物的光色素组成：家犬（Canis familiaris）、海岛灰狐（Urocyon littoralis）、赤狐（Vulpes vulpes）和北极狐（Alopex lagopus）。这四个属具有共同的视锥色素组成；每个属都有一种视锥色素，其峰值敏感度约为555纳米，还有第二种视锥色素，峰值在430 - 435纳米。这些色素测量结果与早期对犬类色觉的研究结论非常吻合，这一事实使得我们能够对野生犬科动物的色觉进行一些预测。另外一组测量结果表明犬类视杆色素的峰值约在508纳米。
