They are the only accessory reproductive glands in male monotremes. Placental mammals usually have one pair of bulbourethral glands, [8] while male marsupials have one to three pairs. [8] [9] [10] Of all domesticated animals, they are absent only in dogs. [4]

[4] As a young male animal reaches puberty, the testicles, which originally were inside the abdominal cavity, move down the inguinal canal to the scrotum. In a ridgling, either the testicles fail to descend, or they are trapped behind the external inguinal ring and cannot ...
Dogs reach puberty between 6 and 24 months old, at which age female dogs will start having an estrous cycle. There are four stages of estrous: proestrus, estrus, diestrus, and anestrus. A dog in estrus, also known as being "in heat", can become pregnant during this 3- to 21-day period. [3]
Animal non-reproductive sexual behavior encompasses sexual activities that non-human animals participate in which do not lead to the reproduction of the species.

Cryptorchidism is common in male dogs, occurring at a rate up to 10%. [19] This condition is one of the most common congenital defects in purebred dogs (11%), with 14% reported in Siberian Huskies. [20] Although the genetics are not fully understood, it is thought to be a recessive, and probably polygenetic, trait. [21]
