Dogs Panosteitis

Panosteitis, also known as 'wandering lameness', 'growing pains', eosinophilic panosteitis, and enostosis, is a disorder of skeletal development characterized by inflammation of the lining of the bone, with the thigh and upper arm bone being most frequently affected. 

The disease is marked by pain and lameness which may be accompanied by fever, muscle wasting, and unthriftiness. A dog can suddenly become reluctant to exercise and lose appetite. Pressure over the shaft of the affected bone elicits pain. The disease routinely affects multiple long bones for a period of weeks to months. 

The lameness shifts from one leg to another and may return to a previously affected leg. The German Shepherd Dog, German Shorthaired Pointer, St. Bernard, Basset Hound, Great Dane and Doberman Pinscher breeds at greater risk and male dogs are four times more frequently affected than females. Panosteitis rarely occurs after 18 tp 20 months of age.

Dogs : Canine Monocytic Ehrlichiosis

Canine monocytic ehrlichiosis (CME), previously known as canine rickettsiosis, canine hemorrhagic fever, tracker dog disease, canine tick typhus, Nairobi bleeding disorder, and tropical canine pancytopenia, is a tick-borne disease caused by rickettsia Ehrlichia canis, a small Gram-negative, coccoid bacterium. Ehrlichia canis is transmitted by the brown dog-tick Rhipicephalus sanguineus. The disease has been reported to occur in Asia, Africa, Europe, and America. To date, no effective vaccine has been developed and tick control remains the most effective preventive measure.

The course of ehrlichiosis can be divided into three phases: acute, subclinical, and chronic, each one being characterized by specific signs. Signs of the acute phase may include depression, lethargy, fever, enlarged lymph nodes, and occasional bleeding under skin and in the internal eye that may result in retinal detachment and blindness. Other clinical signs may include vomiting, clear or pus-filled discharge form the eyes and nose, lameness, loss of movement coordination, and difficulty breathing.

Dog diseases : Juvenile Cellulitis and Complement System

Juvenile Cellulitis

Juvenile cellulitis, also called juvenile pyoderma, puppy strangles, juvenile sterile granulomatous dermatitis and lymphadenitis) is an uncommon disorder of the face, pinnae, and submandibular lymph nodes, usually in puppies. The condition is presumed to be immune-mediated based on histopathological features and response to immunosuppressive forms of therapy. 

A heritable nature has been suggested. Dachshunds, Golden Retrievers, yellow Labrador Retrievers, Gordon Setters, Lhasa Apsos, and Pointers are most commonly affected, but any other breed can have this disease. Most affected animals are less than 4 months old, but occasionally the disorder is reported in adults. Several puppies or only one in the litter may be affected. Signs are characterized by vesicles or pustules in the inner surface of the outer ear, on the muzzle, lips, and eyelids which rapidly progresses to extensive facial swelling, abscesses and draining lesions. 

Dog's Healthy Feeding

If we were limited to using just one modality to treat our patients, it would have to be nutrition. There is little else that can match nutrition for the immediate, significant improvements in health. We have all, unfortunately, spent a generation feeding our animal companions "pet food".

Most commercially prepared foods contain byproducts, additives, preservatives and who knows what else.

Unfortunately we have been indoctrinated to believe that these diets are wonderful, nutritious and balanced for our animals. On paper they might look that way but on paper, the food from any of the fast food franchises also looks healthy. What is important is not only the amount of a nutrient but its source and bio-availability. Many commercial foods are cooked at high temperature and pressure and then extruded. This may take many of those added vitamins and turn them into toxic free radicals. Not a good thing to be feeding our animals. That is why we highly recommend that you feed as natural a diet as you can afford in both time and cost.

Our first choice for our patients is an all natural raw food diet. There are a number of books with recipes and each has their own devotees. For a starting place we recommend using one of the books listed at the end of this paper.

Dog diseases : Intervertebral Disk Disease

The vertebral column, or backbone, consists of 34 individual bones called vertebrae. The vertebral column also includes the spinal cord and nerves, tendons, muscles, ligaments, intervertebral disks, and blood supply. The vertebral column protects the spinal cord and many internal organs, serves as a base of attachment for tendons and ligaments, provides structural support, connects the upper and lower body, and enables a wide range of body movement. The bones in the vertebral column also store minerals and produce red blood cells. The disks separate the vertebrae from each other. 

These "cushions" absorb the stress and shock that the body incurs during movement. IVD degeneration occurs in all breeds of dogs; however, it is observed most frequently in the chondrodystrophoid breeds (Dachshund, Pekingese, French bulldog, Beagle, Basset Hound, American Cocker Spaniel, Shih Tzu, Lhasa Apso, and generally dogs with short thick legs). The intervertebral disk protrusion, characterized by partial protrusion, is seen more commonly in the non-chondrodystrophoid dogs, and usually develops in dogs of 6-10 years of age.

Structure of Intervertebral Disc
The intervertebral disk consists of two regions: the outer layer called annulus fibrosus of cartilage-like material and the central region called nucleus pulposus. The central region is a gel-like structure in the young animal which becomes progressively dehydrated and less gel-like with age.

Dog diseases : Kartagener Syndrome and L-2-hydroxyglutaric Acidemia

Kartagener Syndrome

Kartagener syndrome (KS), also known as Primary Ciliary Dyskinesia (PCD), Kartagener Triad, Kartagener's Syndrome, Kartagener's Triad, and Siewert Syndrome, is is a rare congenital condition associated with abnormal retention of mucus and bacteria in the respiratory tract. The syndrome is caused by mutations of genes encoding proteins which are components of sperm and cilia in the respiratory and the reproductive tracts. Cilia are hairlike structures found in various bodily tissues. Patients with KS may have exercise intolerance and chronic, thick, discharge from the nose. Nasal polyps and ear disease are commonly seen affected individuals. Males with KS may be infertile due to impaired sperm motility.

Ciliated epithelium covers most areas of the upper respiratory tract, including the nasal mucosa, nasal passages, middle ear, eustachian (auditory) tube, and pharynx (throat). The lower respiratory tract contains ciliated epithelium from the trachea to the respiratory bronchioles. Cilia propel overlying mucus via a 2-part ciliary beat cycle. 

Dogs : Lens Luxation And Subluxation

Dislocation, or luxation, of the lens arises as a result of rupture of the zonular fibers, which suspend the lens from the ciliary body. In the dog, lens luxation is most frequently encountered as a primary, heritable condition in which there appears to be an inherent weakness of the zonule. In subluxation the lens remains in its normal position, but will be shifted down or to one side. 

In anterior luxation the lens may go through the pupil and lie in the anterior chamber, where it may rub against the cornea and cause corneal inflammation. Two forms of lens luxation have been described in dogs: traumatic and primary. Traumatic form is characterized by a severe concurrent intraocular damage. Traumatic lens displacements usually have a poor prognosis due to the severity of ocular damage.

Primary lens luxation is seen most frequently in the Wirehaired Fox Terrier, Sealyham, Welsh and Manchester Terrier, and occasionally in the Boston Terrier, Basset Hound, Border Collie, and Cocker Spaniel. The lens usually does not displace, however, until the individual is 2 to 5 years old. 

Dogs : Adrenal Cortical Atrophy

Adrenal cortical atrophy is the destruction of the outer layer of the adrenal glands which results in insufficient production of mineralocorticoid and glucocorticoid hormones. The adrenals are two crescent-shaped glands that sit on top of each kidney and secrete hormones directly into the bloodstream. They are divided anatomically and functionally into two main parts: the medulla (middle) and the cortex (rind). Furthermore, each division of an adrenal gland consists of internal layers that produce different hormones. Constant stress and poor nutrition can weaken the adrenal glands.

When stress continues over prolonged periods of time, the body's hormonal and energy reserves become depleted, and the glands may either shrink in size or enlarge. The destruction of the adrenal glands is a gradual process. Initially partial destruction of the adrenal cortex produces symptoms that are only obvious during stressful situations such as boarding, travel or surgery. 

Dogs : Acute Peritonitis

Peritonitis is an inflammation of the peritoneum, the membrane lining the walls of the abdominal and pelvic cavities and covering contained internal organs. In small animals, acute septic peritonitis is a relatively common and important condition with high mortality rates.

Fluids, organic debris, cells, infectious organisms, and pus accumulate in the cavity in acute peritonitis. The causes can be from external injury or internal infections or diseases, such as bowel puncture from trauma, rupture from disease or ingested foreign bodies, with escape of contaminated bowel contents into the abdominal cavity; infections from abdominal cavity puncture, or after surgery, or spreading from infections in other abdominal organs or other areas of the body; damage to the urinary system, with escape of urine into the abdominal cavity; damage to the pancreas or liver with escape of bile or pancreatic enzymes into the abdominal cavity; and rupture of an infected uterus or prostate gland. 

Dogs : Canine Cone Degeneration and Acromegaly

Canine Cone Degeneration

Achromatopsia, also called rod monochromacy, is an inherited condition characterized by decreased visual acuity, absent color vision, photophobia, and nystagmus. Achromatopsic humans report that colored objects appear in shades of gray. Two forms of this condition have been described in humans. 

Complete achromatopsia is a congenital vision disorder in which all cone function is absent or severely diminished. The incomplete (atypical) form is defined as dyschromatopsia, in which the symptoms are similar to those of the complete achromatopsia (typical) form but with less visual dysfunction. 

In dogs, the condition is referred to as canine cone degeneration. Cones are light-sensitive retinal photoreceptors in the vertebrate eye. Although cone cells account for only 5% of photoreceptors, they are essential for high-acuity daylight-vision and discrimination of color. Canine cone degenration is caused by mutation in the canine GNGB3 gene. In the Alaskan Malamute, the complete gene is deleted, while in the German Shorthaired Pointer, the gene has substituted amino acids.
