Behavior
This robust, courageous dog has great endurance, but does not always have a good disposition. The Dachshund is independent, belligerent, has a tendency to bite, and tries to exert his dominance over other dogs. His habit of barking at the least noise makes him a good guard dog. The Dachshund is affectionate and cheerful, but tends to be possessive and often jealous. The smooth variety is the most energetic, while the wirehaired variety is the most rustic and has the greatest hunting instinct. The longhaired variety is the calmest of the three. All Dachshunds must receive firm but gentle training from a very young age.
The Dachshund is well-suited to life as a house dog, particularly the longhaired variety. However, this small dog needs plenty of exercise to maintain his mental health. The wirehaired and longhaired varieties require regular brushing and combing.
Dachshunds can be difficult to housebreak, and patience and consistency are often needed in this endeavor.
According to the American Kennel Club's breed standards, "the dachshund is clever, lively and courageous to the point of rashness, persevering in above and below ground work, with all the senses well-developed. Any display of shyness is a serious fault." Their temperment and body language give the impression that they do not know or care about their relatively small size. Like many small hunting dogs, they will challenge a larger dog. Indulged dachshunds may become snappy or extremely obstinate.
Many dachshunds do not like unfamiliar people, and many will growl or bark at them. Although the dachshund is generally an energetic dog, some are sedate. This dog's behavior is such that it is not the dog for everyone. A bored, untrained dachshund will become destructive. If raised improperly and not socialized at a young age, dachshunds can become aggressive or fearful. They require a caring, loving owner who understands their need for entertainment and exercise.
Dachshunds may not be the best pets for small children. Like any dog, dachshunds need a proper introduction at a young age. Well-trained dachshunds and well-behaved children usually get along fine. Otherwise, they may be aggressive and bite an unfamiliar child, especially one that moves quickly around them or teases them. However, many dachshunds are very tolerant and loyal to children within their family, but these children should be mindful of the vulnerability of the breed's back.
Health
The breed is prone to spinal problems, especially intervertebral disk disease (IVDD), due in part to an extremely long spinal column and short rib cage. The risk of injury may be worsened by obesity, jumping, rough handling, or intense exercise, which place greater strain on the vertebrae. About 20–25% of dachshunds will develop IVDD. Dachshunds with a number of calcified intervertebral discs at a young age have a higher risk of developing disc disease in later life. In addition, studies have shown that development of calcified discs is highly heritable in the breed. An appropriate screening programme for IVDD has been identified by Finnish researchers and a UK IVDD screening programme has been developed for breeders with the aim to reduce prevalence of spinal problems.
Treatment consists of combinations of crate confinement and courses of anti-inflammatory medications (steroids and non-steroidal anti-inflammatory drugs like carprofen and meloxicam), or chronic pain medications, like tramadol. Serious cases may require surgery to remove the troublesome disk contents. A dog may need the aid of a cart to get around if paralysis occurs.
A minimally invasive procedure called "percutaneous laser disk ablation" has been developed at the Oklahoma State University Veterinary Hospital. Originally, the procedure was used in clinical trials only on dachshunds that had suffered previous back incidents. Since dachshunds are prone to back issues, the goal is to expand this treatment to dogs in a normal population.
In addition to back problems, the breed is prone to patellar luxation where the kneecap can become dislodged. Dachshunds may also be affected by osteogenesis imperfecta (brittle bone disease). The condition seems to be mainly limited to wire-haired Dachshunds, with 17% being carriers. A genetic test is available to allow breeders to avoid breeding carriers to carriers. In such pairings, each puppy will have a 25% chance of being affected.
In some double dapples, there are varying degrees of vision and hearing loss, including reduced or absent eyes. Not all double dapples have problems with their eyes and/or ears, which may include degrees of hearing loss, full deafness, malformed ears, congenital eye defects, reduced or absent eyes, partial or full blindness, or varying degrees of both vision and hearing problems; but heightened problems can occur due to the genetic process in which two dapple genes cross, particularly in certain breeding lines. Dapple genes, which are dominant genes, are considered "dilution" genes, meaning whatever color the dog would have originally carried is lightened, or diluted, randomly; two dominant "dilution" genes can cancel each other out, or "cross", removing all color and producing a white recessive gene, essentially a white mutation. When occurring genetically within the eyes or ears, this white mutation can be detrimental to development, causing hearing or vision problems.
Other dachshund health problems include hereditary epilepsy, granulomatous meningoencephalitis, dental issues, Cushing's syndrome, thyroid and autoimmune problems, various allergies and atopies, and various eye conditions including cataracts, glaucoma, progressive retinal atrophy, corneal ulcers, nonucerative corneal disease, sudden acquired retinal degeneration, and cherry eye. Dachshunds are also 2.5 times more likely than other breeds of dogs to develop patent ductus arteriosus, a congenital heart defect. Dilute color dogs (Blue, Isabella, and Cream) are very susceptible to color dilution alopecia, a skin disorder that can result in hair loss and extreme sensitivity to sun. Since the occurrence and severity of these health problems is largely hereditary, breeders are working to eliminate these.
Factors influencing the litter size of puppies and the proportion of stillborn puppies per litter were analyzed in normally sized German dachshunds. The records analyzed contained data on 42,855 litters. It was found that as the inbreeding coefficient increased, litter size decreased and the percentage of stillborn puppies increased, thus indicating inbreeding depression. It was also found that young and older dams had smaller litter sizes and more stillborn puppies than middle-aged dams.
