在家犬中，研究了犬吠和咆哮的发声特征，以及咆哮的个体体型和发声特征之间的关系，但对哀鸣的相应信息较少。在本研究中，我们研究了16个品种的20只成年伴侣犬(雄性9只，雌性11只)的鸣叫频率和时间特征，体质量范围从3.5kgGg到70.0kgkg，属于16个品种。狗的叫声(每个人26-71声，总共824声)被记录在由狗主人模拟的条件乞讨环境中。叫声有3个独立的基频：低、高和超高频率，分别作为单音叫声或同时作为两声双音或三声复音的叫声出现。从最小到最大，低频的频率上限为0.24~2.13 khz，高频的上限为2.95~10.46 khz，超高频的频率上限为9.99~23.26 khz。在个体内，单声道的低基频低于双声道的哀鸣，而高基频在不同的哀鸣类型之间没有差异。低频、高频和超高频的所有频率变量均与犬体质量呈负相关。在持续时间方面，没有发现与体重相关。我们讨论了每个基频的潜在产生机制和声源；指出了高频狗鸣和啮齿动物超声波叫声之间的声学相似性，并假设超高基频的作用是允许社会团体成员之间进行私人的、“聊天”的交流。
In domestic dogs Canis familiaris, vocal traits have been investigated for barks and growls, and the relationship between individual body size and vocal traits investigated for growls, with less corresponding information for whines. In this study, we examined the frequency and temporal traits of whines of 20 adult companion dogs (9 males, 11 females), ranging in body mass from 3.5 to 70.0 kg and belonging to 16 breeds. Dog whines (26–71 per individual, 824 in total) were recorded in conditioned begging contexts modeled by dog owners. Whines had 3 independent fundamental frequencies: the low, the high and the ultra-high that occurred singly as monophonic calls or simultaneously as 2-voice biphonic or 3-voice polyphonic calls. From the smallest to largest dog, the upper frequency limit varied from 0.24 to 2.13 kHz for the low fundamental frequency, from 2.95 to 10.46 kHz for the high fundamental frequency and from 9.99 to 23.26 kHz for the ultra-high fundamental frequency. Within individuals, the low fundamental frequency was lower in monophonic than in biphonic whines, whereas the high fundamental frequency did not differ between those whine types. All frequency variables of the low, high, and ultra-high fundamental frequencies correlated negatively with dog body mass. For duration, no correlation with body mass was found. We discuss potential production mechanisms and sound sources for each fundamental frequency; point to the acoustic similarity between high-frequency dog whines and rodent ultrasonic calls and hypothesize that ultra-high fundamental frequencies function to allow private, “tete-a-tete” communication between members of social groups.
