The Rat Terrier is an American dog breed with a background as a farm dog and hunting companion. [1] They share much ancestry with the small hunting dogs known as feists . Common throughout family farms in the 1920s and 1930s, they are now recognized by the United (UKC) and American Kennel Clubs (AKC) and are considered a rare breed. [ 2 ]
A white-tailed deer's tail. The tail is the elongated section at the rear end of a bilaterian animal's body; in general, the term refers to a distinct, flexible appendage extending backwards from the midline of the torso.

[1] [2] Neither bitch whelped another hairless pup in multiple litters until, in 1981 at the age of nine, Josephine produced two more hairless pups, a dog and ...

A closeup of a rat tail. The characteristic long tail of most rodents is a feature that has been extensively studied in various rat species models, which suggest three primary functions of this structure: thermoregulation, [13] minor proprioception, and a nocifensive-mediated degloving response.

The breed is an agile dog with a lean and athletic build; the head is triangular with a semi-flat skull. The eyes are very dark and the Ratonero has a long muzzle, and high set ears that bend over at the tip. The tail is traditionally docked to one quarter of its length, [2] however they may also be born with a natural bobtail. [4]
People whose dogs had the most eye contact with them - a mutual gaze - registered the largest increases in oxytocin levels. The dogs also had an oxytocin spike correlating with that of their owner.
Dogs have ear mobility that allows them to rapidly pinpoint the exact location of a sound. Eighteen or more muscles can tilt, rotate, raise, or lower a dog's ear. A dog can identify a sound's location much faster than a human can, as well as hear sounds at four times the distance. [41] Dogs can lose their hearing from age or an ear infection. [42]
