A dog's glans consists of two sections: Behind the lower, long part (pars longa glandis) lies the "knot" (Bulbus glandis) [1] which expands only after penetrating the vagina and causes the male dog to remain inside the bitch ("Tie") for some time after ejaculation (typically between 15 and 30 min).
For domestic dogs the tie may last up to half an hour or more, though usually less. [7] When male canines are sexually excited, the bulbus glandis may swell up inside the penile sheath, even if the dog has been neutered. [8] The bulbus glandis also occurs in the penises of some pinnipeds, including South American fur seals. [9]
In the greater short-nosed fruit bat, copulation by males is dorsoventral and the females lick the shaft or the base of the male's penis, but not the glans which has already penetrated the vagina. While the females do this, the penis is not withdrawn and research has shown a positive relationship between length of the time that the penis is ...
The clitoris (/ ˈ k l ɪ t ər ɪ s / ⓘ or / k l ɪ ˈ t ɔːr ɪ s / ⓘ; pl.: clitorises or clitorides) is a female sex organ present in mammals, ostriches and other amniotes.. Although the clitoris exists in all mammal species, [1] [2] [3] most studies deal with the human clitoris - few detailed studies of the anatomy of the clitoris in non-humans exist. [4]
Cloaca of a red-tailed hawk. A cloaca (/ k l oʊ ˈ eɪ k ə / ⓘ kloh-AY-kə), pl.: cloacae (/ k l oʊ ˈ eɪ s i / kloh-AY-see or / k l oʊ ˈ eɪ k i / kloh-AY-kee), or vent, is the rear orifice that serves as the only opening for the digestive (), reproductive, and urinary tracts (if present) of many vertebrate animals.
According to a 2020 study, humans have a visual field of up to 190 degrees, while dogs' visual field varies greatly from breed to breed but can extend up to 240 degrees in dogs with laterally ...
Animal non-reproductive sexual behavior encompasses sexual activities that non-human animals participate in which do not lead to the reproduction of the species. Although procreation continues to be the primary explanation for sexual behavior in animals, recent observations on animal behavior have given alternative reasons for the engagement in sexual activities by animals.

A notable example of a bird with a pseudo-penis is the red-billed buffalo weaver, which do not use their pseudo-penis for direct insertion during copulation; however it does play a part in successful mating and stimulation. [15] Similarly to the red-billed buffalo weaver, the cassowary, a ratite, exhibits a pseudo-penis in both males and females.
