Degenerative myelopathy (DM), a disease affecting the spinal cord, results in slowly progressive hind limb weakness and paralysis. It is considered a disease of middle-aged to older dogs, including German shepherds, German shepherd crosses, Siberian huskies, and collies. It will be suspected based on breed, medical history, physical examination, and diagnostic tests. Unfortunately, there is no effective treatment, and it is a progressive, incurable disease.

Demodectic mange is caused by a parasitic mite that lives in the hair follicles of dogs. As long as the body's immune system is functioning properly, these mites cause no harm. Demodectic mange most often occurs when a dog has an immature or weakened immune system, allowing the number of skin mites to increase rapidly. Topical, oral, and injectable medications are available to treat demodectic mange.

Miliary Dermatitis in Cats
La dermatitis miliar es un término general usado para describir una condición cutánea en los gatos que normalmente suele ser consecuencia de una reacción alérgica. Debido a que la mayoría de las dermatitis alérgicas o reacciones de la piel en los gatos son provocadas por una alergia a las pulgas, los dos términos han llegado a ser sinónimos.

Dermatomyositis is hereditary, immune-mediated disease of the skin muscles and blood vessels affecting primarily collies, Shetland Sheepdogs and mixes of these breeds. Other breeds can experience similar disease. Signs are usually first recognized in puppies but can present in young adulthood. Signs include: skin lesions (crusty erosions, patchy alopecia or ulcers) around the eyes, lips, face, ear flaps or tail tip, foot pad lesions; atrophy of chewing muscles or difficulty chewing; stiff gait and megaesophagus in severely affected dogs. Skin biopsies are diagnostic. Treatment involves treating secondary bacterial infections, reducing sun exposure, EFAs, and immunomodulatory medications including tetracycline, niacinamide, pentoxifylline, cyclosporine and corticosteroids. Prognosis varies depending on severity.

Testing for diabetes includes confirming hyperglycemia and glucosuria while looking for other conditions by taking a complete blood count (anemia, infection), biochemistry profile (hepatic disease, pancreatitis), and a urinalysis (urinary tract infection). Monitoring includes regular glucose curves and additional exams and testing based on the pet owner's monitoring of their cat's clinical signs at home. Urine glucose testing and fructosamine are sometimes used in diabetic monitoring and urine testing for infection may be recommended.

Diabetes insipidus is rare in cats and is characterized by excessive drinking and the production of enormous volumes of extremely dilute urine. Despite drinking large volumes of water, the cat can become dehydrated from urinating so much. Increased drinking and urination are common signs of several other health conditions, so it is essential that several diagnostic tests be performed to diagnose diabetes insipidus. While the condition is rarely curable, it is usually successfully controlled.

Diabetes insipidus results in excessive drinking and urination. As many conditions cause these signs, a number of diagnostic tests including bloodwork and urinalysis need to be performed to rule out other causes. After more common causes are ruled out, a modified water deprivation test can confirm disease and an MRI or therapeutic trial can be performed. Diabetes insipidus results from reduced production of ADH from the brain or reduced sensitivity to ADH in the kidney. Treatment depends on the cause of the disease either replacing the lack of ADH with a synthetic replacement or using a hydrochlorothiazide and a low salt diet to decrease urine production.

Diabetes Mellitus in Dogs: Overview
La diabetes mellitus es una enfermedad del páncreas. El páncreas es un pequeño pero vital órgano localizado cerca del estómago. Tiene dos tipos diferentes de poblaciones de células. Uno de los grupos de células produce los enzimas necesarios para la digestión. El otro grupo de células, las células beta, producen la hormona insulina. La insulina regula los niveles de glucosa en la sangre y controla la liberación de glucosa a los tejidos del organismo. En términos simples, la diabetes mellitus esta provocada por un fallo del páncreas en la regulación del azúcar sanguíneo.

Diabetes is an inability of the body to regulate blood sugar caused by an abnormality of the pancreas. It is the second-most common endocrine disease in cats. It causes increased thirst, urination, appetite, and weight loss. Cats most commonly have type 2 diabetes, caused by decreased insulin production or insulin resistance, and it is often associated with obesity. Diabetes is diagnosed by measuring increased levels of glucose in the urine and blood. Diabetes treatment includes insulin injections and dietary changes. Changes in blood sugar must be monitored regularly.
