where does a male dog enter a female dog
Canine reproduction Male canines are the only animals that have a locking bulbus glandis or "bulb", a spherical area of erectile tissue at the base of the penis. During copulation, and only after the male's penis is fully inside the female's vagina, the bulbus glandis becomes engorged with blood.[9] In coyotes, when the female's vagina subsequently contracts, the penis becomes locked inside the female.[10] This is known as "tying" or "knotting". While characteristic of mating in most canids, the copulatory tie has been reported to be absent[11] or very brief (less than one minute)[12] in the African wild dog, possibly due to the abundance of large predators in its environment.[13]
A Dog's Purpose (film) His strong spirit is reborn and reincarnated as a newborn Retriever puppy in 1961. Toby leaves his cage at a puppy mill and is found by two garbage men who plan to sell him for their own profit. They leave to drink and Toby is spotted locked inside their pick-up truck by a young boy named Ethan and his mother, who rescue him from the brink of death by heatstroke. After they convince Ethan's father, the dog is allowed to stay and renamed Bailey.
