• Diabetes Mellitus: Principles of Treatment in Dogs

  Diabetes mellitus is an inability to regulate blood glucose caused by a loss of insulin production (Type I) or inadequate insulin supply or resistance (Type II). Dogs need insulin injections to manage diabetes. Sometimes special diets may help manage the disease. Response to insulin needs to be monitored to ensure adequate dosing and to avoid hypoglycemia caused by insulin overdose. Blood glucose curves are most commonly used for this including: in-clinic blood glucose curves, home glucose curves with hand-held glucometers and continuous glucose monitoring systems. Urine glucose testing and fructosamine testing may also be used to manage the disease. Hypoglycemia is the consequence of administering too much insulin compared to the amount of food ingested. Signs can range from lethargy to seizures and coma. It can be managed acutely with administration of sugar syrup to the gums but more severely affected dogs will need IV dextrose solutions.

• Diarrhea in Dogs

  Diarrhea is a symptom of an underlying problem that may be minor or very serious. Some cases may resolve on their own or with minimal treatment, while other cases require in-depth diagnostic testing and more aggressive treatment to address the underlying condition. The possible causes, diagnostic tests, and treatment protocols for diarrhea in dogs are numerous and are explained in this handout.

• Diarrhea Questionnaire for Dogs

  If your dog is having diarrhea, please complete this questionnaire as accurately as possible before your appointment. This information will be very helpful to your veterinarian in determining the cause of diarrhea.

• Discoid (Cutaneous) Lupus Erythematosus

  Discoid Lupus Erythematosus (DLE) is an autoimmune condition that causes skin sloughing particularly around the nose causing scabbing and erosions that can become infected with bacteria. It can also affect the ear flaps, genitals and rarely spread through the entire body. DLE is diagnosed by submitting skin biopsies of affected areas for histopathological analysis. As well as antibiotics to treat secondary bacterial infections, treatment involves suppression of the immune system including tacrolimus or steroid ointments/creams applied to the affected area. Some dogs will need tetracycline and niacinamide or stronger anti-inflammatories such as cyclosporine or corticosteroids. These treatments can be weaned once lesions resolve but flare-ups will likely occur, needing rechecks and repeat therapy. Sun exposure must be minimized as UV light can worsen the disease. If untreated, lesions can develop into squamous cell carcinoma.

• Discospondylitis/Diskospondylitis

  Discospondylitis is a bacterial or fungal infection of the intervertebral disks and the adjacent vertebral bones. It primarily affects dogs, though rarely can affect cats. It affects large breed dogs more often and generally starts clinically as back pain. The diagnosis and treatment of this condition are outlined in this handout.

• Disobedient, Unruly, and Hyperactive Dogs

  Dogs exhibit many normal behaviors that can seem unruly. Some dogs are overly active and never seem to settle. Attempts to stop disruptive, normal behaviors using corrections are not typically successful. Effective techniques rely on training desired responses instead. Sometimes, even when trained, dogs do not listen. This is usually due to a lack of understanding rather than deliberate disobedience. Retraining basic skills can be helpful.

• Distemper in Dogs

  Distemper virus is a highly contagious disease that can affect multiple body systems and is potentially fatal. Puppies are most susceptible, and respiratory, gastrointestinal, or neurologic signs may be seen. Vaccines are available and are highly effective at preventing disease.

• DNA Testing

  DNA is a large complex molecule that carries the genetic information or genetic code of an organism. All common forms of life, such as viruses, bacteria, plants, and animals carry a copy of their own genetic code in each of their cells. Each organism has a unique section of DNA that is just like a fingerprint. DNA-PCR is often used to detect the presence of infectious organisms; especially when detecting extremely small numbers of infectious organisms and for detecting certain viruses and bacteria that are difficult to diagnose by other methods.

• Do Dogs Mourn?

  Just like people, your dog can mourn when there has been a loss in their world, and the symptoms are similar. There are ways that you can help, with some guidance from your veterinarian or a behaviorist if needed.

• Do Dogs Recognize Facial Expressions?

  The simple answer to a complicated, much researched question is, yes! Dogs do recognize our facial expressions which makes them wonderful family members.
