👉 Dogtail is a term used to describe a type of hair pattern on dogs that can vary in length and thickness. It typically appears along the sides or back of the dog's coat, often starting at the tip of the tail and gradually spreading outwards towards the crown of the head. The term "dogtail" was first coined by veterinarian Dr. John H. Brown in 1934 to describe this particular pattern on a male dog named Frank.
