This page features Companion Dog group breeds, offering detailed information for anyone interested in learning about these dogs. Each breed profile includes key traits such as temperament, size, energy level, and general care needs.
Many of these breeds originated in one of the other seven Groups but have been specially adapted to serve as family companions. With the exception of the English Bulldog and the Dalmatian, the Companion Dogs tend to be “miniaturized” versions of their ancestors. Companion Dogs are lively, intelligent, and affectionate.

The Biewer Terrier, pronounced BEE-VARE, is a toy breed that shares a close lineage with the Yorkshire Terrier. Renowned for its cheerful disposition, lively spirit, and sharp intelligence, this breed can present challenges in housetraining due to its petite size, necessitating dedication and patience from its owner. The Biewer Terrier is quite vocal and brimming with energy. Although generally friendly, it tends to be cautious around unfamiliar faces, often displaying signs of anxiety when meeting new people or dogs. To keep this spirited pup safe during play, a securely fenced yard is crucial; however, it’s important never to leave the dog outside unsupervised, as it could be vulnerable to predatory birds.

The Tibetan Spaniel, celebrated for its independent spirit and gentle demeanor, was originally bred by Buddhist monks in Tibet. This breed is reminiscent of a lion, which holds significant meaning in Buddhism. While it shares some characteristics with the Pekingese, the Tibetan Spaniel features a slightly elongated face and does not possess the excessive skin commonly found in that breed. Its body is longer than it is tall, complemented by a small, rounded head that is well-proportioned to its frame. The muzzle is of medium length and smooth, free from wrinkles, while its dark, widely spaced eyes add to its charm. This delightful dog is adorned with a silky, flat double coat and a feathery tail that arches gracefully over its back, along with a longer mane around its neck. Historically, this loyal breed functioned as both a watchdog and a companion, alerting its owners to potential dangers with its distinctive bark. To maintain the health of its coat, regular grooming is vital, requiring daily brushing and combing to avoid matting. The Tibetan Spaniel has moderate energy levels, so it is important to provide adequate mental and physical stimulation to keep it engaged and stave off boredom.

The contemporary Yorkshire Terrier is a small breed primarily valued for companionship. In stark contrast, its forebears were much larger and were utilized for hunting small rodents and other vermin. It is thought that the Yorkshire Terrier emerged from a mix of several terrier breeds, with some contributions from the Maltese. Among these breeds are the Skye Terrier, Dandie Dinmont, Manchester Terrier, and the now-extinct Paisley or Clydesdale Terrier. Over the years, this brave little hunting dog evolved into a trendy pet, so petite that many women now carry them in handbags or under their arms. The American Kennel Club officially recognized the Yorkshire Terrier in 1885.

The Bolognese, a breed that hails from northern Italy, is celebrated as a companion dog and is one of the oldest breeds in Europe, with origins dating back to the 12th century. In the United States, however, this breed remains relatively rare. Bolognese dogs are known for their intelligence and ability to learn quickly, making them generally easy to train, although they may show a hint of stubbornness at times. Their unique, thick, curly white coat necessitates daily brushing and occasional professional grooming to keep it in good shape. Affectionately called Bolos, these dogs are low-energy and adapt well to living in apartments. Since they were specifically bred for companionship, they struggle with being left alone, which can lead to separation anxiety and result in unwanted behaviors like barking, chewing on furniture, or urinating indoors. Furthermore, due to their small size and potential delicacy, Bolognese dogs may not be the best fit for families with young children.

The Miniature Pinscher should not be mistaken for a diminutive version of the Doberman Pinscher; instead, it is more accurately described as a small-scale likeness of its larger relative. Interestingly, the Miniature Pinscher actually predates the Doberman. Often referred to as the Min Pin, this breed originates from the German Pinscher lineage and may also share ancestry with the Italian Greyhound and Dachshund. While the Miniature Pinscher has been officially recognized for over two centuries, the specifics of its ancestral background continue to spark discussion among enthusiasts. Nevertheless, this distinguished breed has been featured in Renaissance art, and artifacts from as far back as 2,000 years ago attest to its enduring existence.

The Affenpinscher, commonly known as the "monkey dog," gets its name from a German term that reflects its playful appearance, particularly its resemblance to primates. Initially bred for hunting rats, these dogs were also referred to as ratters. The breed originated in Germany during the 17th and 18th centuries, evolving from various small terrier breeds. Their small stature and loving disposition made them popular as lapdogs among women, leading breeders to focus on creating even smaller versions. Typically, Affenpinschers reach a height of 9 to 11 inches and weigh about 9 pounds. They have medium-length, wiry fur that comes in several colors, including belge, tan, red, silver, gray, and black. Nowadays, this breed is relatively rare and not commonly found. It is recommended to keep Affenpinschers away from households with young children, as they generally dislike being squeezed or chased.
