The Appenzeller Sennenhund is a medium-size breed of dog, one of the four regional breeds of Sennenhund-type dogs from the Swiss Alps. The name Sennenhund refers to people called Senn, herders in the Swiss Alps. Appenzell is an alpine region in the northeast of Switzerland.

Appearance

The Appenzeller Sennenhund is a large dog, 18.5-23 ins (47-58 cm) at the withers and weighing 49-70 lbs (22-32 kg). Like the other Sennenhunds, the Appenzeller Sennenhund has a heavy, molosser-like build and a distinctive tricolour coat. The breed's ears are small and triangular, set high and hanging down against the dog's cheeks, similar to a button ear. Faults in the breed's appearance include wall eye, kinked tail, a single coat, and a coat that is not tricolour.

Four breeds of Sennenhund

The four breeds of Sennenhund, with the original breed name followed by the most popular English version of the breed name.

• Grosser Schweizer Sennenhund, Greater Swiss Mountain Dog

• Berner Sennenhund, Bernese Mountain Dog

• Appenzeller Sennenhund, Appenzeller

• Entlebucher Sennenhund, Entlebucher Mountain Dog

History and purpose

The Appenzeller Sennenhund is descended from the general Sennenhund type which may have existed in antiquity, or descended from "cattle dogs left there by the Romans", but the first breed club for the breed was founded and the stud book for the breed started in 1906 by Albert Heim and others, who wrote the first breed standard in 1916. An early reference to the breed's predecessors was made in an 1853 book, "Tierleben der Alpenwelt" (Animal Life in the Alps), referring to dogs in the Appenzell region. The Appenzeller Sennenhund was only recognised internationally as a separate breed in 1989.

The Appenzeller Sennenhund was originally kept as a flock guardian, a draft dog, and general farm dog. The breed also was used for herding and as a guard dog. Today the breed is primarily kept as a companion, and excels in obedience competitions and Schutzhund.

Temperament

As with all large, very active working dogs, this breed should be well socialized early in life with other dogs and people and provided with regular activity and training if they are to be safely kept as a pet. According to the breed standard, the dogs are lively, high spirited, and suspicious of strangers.

Kennel club recognition

The breed is recognised with the Swiss breed standard under the name Appenzeller Sennenhund, translated into English as Appenzell Cattle Dog, by the Fédération Cynologique Internationale in Group 2 Pinscher and Schnauzer- Molossoid breeds- Swiss Mountain and Cattle Dogs and other breeds, Section 3 Swiss Mountain and Cattle Dogs. The breed is also recognised in the United States by the United Kennel Club in their Guardian Dog Group under the name Appenzeller, and is listed as a breed in the Foundation Stock Service by the American Kennel Club with the name Appenzeller Sennenhunde. The breed is not currently recognised by The Kennel Club or the other major kennel clubs in the English-speaking world, although it is also registered by small clubs and internet-based breed registries, and is promoted in North America as a rare breed for puppy buyers seeking a unique pet.

Breeding / Reproduction

In domestic dogs, sexual maturity begins to happen around age six to twelve months for both males and females, although this can be delayed until up to two years old for some large breeds. This is the time at which female dogs will have their first estrous cycle. They will experience subsequent estrous cycles biannually, during which the body prepares for pregnancy. At the peak of the cycle, females will come into estrus, being mentally and physically receptive to copulation. Because the ova survive and are capable of being fertilized for a week after ovulation, it is possible for a female to mate with more than one male.

Dogs bear their litters roughly 56 to 72 days after fertilization, with an average of 63 days, although the length of gestation can vary. An average litter consists of about six puppies, though this number may vary widely based on the breed of dog. Toy dogs generally produce from one to four puppies in each litter, while much larger breeds may average as many as twelve.

Some dog breeds have acquired traits through selective breeding that interfere with reproduction. Male French Bulldogs, for instance, are incapable of mounting the female. For many dogs of this breed, the female must be artificially inseminated in order to reproduce


Neutering

Neutering refers to the sterilization of animals, usually by removal of the male's testicles or the female's ovaries and uterus, in order to eliminate the ability to procreate and reduce sex drive. Because of the overpopulation of dogs in some countries, animal control agencies, such as the American Society for the Prevention of Cruelty to Animals (ASPCA), advise that dogs not intended for further breeding should be neutered, so that they do not have undesired puppies that may have to later be euthanized.

According to the Humane Society of the United States, 3–4 million dogs and cats are put down each year in the United States and many more are confined to cages in shelters because there are many more animals than there are homes. Spaying or castrating dogs helps keep overpopulation down. Local humane societies, SPCAs, and other animal protection organizations urge people to neuter their pets and to adopt animals from shelters instead of purchasing them.

Neutering reduces problems caused by hypersexuality, especially in male dogs. Spayed female dogs are less likely to develop some forms of cancer, affecting mammary glands, ovaries, and other reproductive organs. However, neutering increases the risk of urinary incontinence in female dogs, and prostate cancer in males, as well as osteosarcoma, hemangiosarcoma, cruciate ligament rupture, obesity, and diabetes mellitus in either gender.

Dog Communication

Dog communication refers to body movements and sounds dogs use to send signals to other dogs, and other animals (usually humans). Dog communication comes in a variety of forms, and is part of the foundation of dog social behavior (see Dog Society). Dogs use certain movements of their bodies and body parts and different vocalizations to send signals. There are a number of basic ways a dog can communicate. These are movements of the ears, eyes, eyebrows, mouth, head, tail, and entire body, as well as barks, growls, whines and whimpers, and howls.

It is important to note that while many gestures and actions have common, stereotypical meanings, researchers regularly seem to find that animal communication is often more complex and subtle than previously believed, and that the same gesture may have multiple distinct meanings depending on context and other behaviors. So, generalizations such as "X means Y" are often, but not always accurate. For example, even a simple tail wag may (depending on context) convey many meanings including:

• Excitement

• Anticipation

• Playfulness

• Contentment/enjoyment

• Happy, self-confidence

But also:

• Anxiety

• Questioning another animal or a human as to intentions

• Tentative role assessment on meeting another animal

• Reassurance ("I'm friendly, are you?")

• Reconciliation (after an aggressive interaction: "I still want to be friends")

• Uncertainty/apprehension

• Submissive placation

Combined with other body language, in a specific context, many gestures such as yawns and direction of vision all convey meaning. Panting may mean "Too hot"; it might also mean either emotional anxiety or happiness. Thus statements that a particular action "means" something should always be interpreted to mean "often means" something. As with human beings, who may smile or hug or stand a particular way for multiple reasons, many animals reuse gestures too.

Health risks to humans

In the USA, dogs cause 88% of the 86,000 falls caused by pets. Dog feces can cause a number of human diseases, including toxocariasis, which can cause blindness, and can also cause human hookworm. In the United States, about 10,000 cases of Toxocara infection are reported in humans each year. Almost 14% of the US population is infected with Toxocara, a parasite of dogs and cats that can be passed from animals to humans.

The incidence of dog bites, and especially fatal dog bites, is extremely rare in America considering the number of pet dogs in the country. Fatalities from dog bites occur in America at the rate of one per four million dogs. A Colorado study found that bites in children were less severe than bites in adults. The incidence of dog bites in the US is 12.9 per 10,000 inhabitants, but for boys aged 5 to 9 the incidence rate is 60.7 per 10,000. Moreover, children have a much higher chance to be bitten in the face or neck. Sharp claws with powerful muscles behind them can lacerate flesh in a scratch that can lead to serious infections.

In the UK between 2003 and 2004, there were 5,868 dog attacks on humans resulting in 5,770 working days lost in sick leave.
