Dog health conditions

A saddle thrombus is when a large blood clot becomes lodged in the aorta, obstructing blood flow to the hind limbs in dogs. The aorta is a large artery which carries blood from the heart to the rest of the body

Sago palm poisoning in dogs is a potentially fatal condition caused by the ingestion of all parts of the Cycas revoluta plant.

Salmonella poisoning in dogs is caused by infection of Salmonella bacteria, which is usually ingested through contaminated food or water. Dogs tend to show no symptoms of salmonella infection, despite shedding the bacteria in their feces and contaminating the environment.

Salmon poisoning disease (SPD) is a potentially life-threatening infectious disease that affects dogs and other members of the canine species. SPD is transmitted by a parasitic flatworm found in raw fish that is commonly infected with the Neorickettsia helminthoeca bacteria

Salt toxicosis occurs when dogs consume too much sodium.

Sarcoptic mange is a specific type of mange that occurs in dogs with an infestation of Sarcoptes scabiei - a parasitic mite that burrows along the surface of the skin in places with sparse hair including the outer ears, abdomen, and elbows.

Seasonal allergies are a common condition in dogs. Most seasonal allergy symptoms in dogs result from exposure to flea saliva and/or pollen.

Seasonal nasal hypopigmentation (SNH), aka “snow nose” in dogs, describes a seasonal loss of nasal pigment (called melanin) resulting in a lighter, pink colored nose. The cause is unknown but may involve light or temperature-dependent enzymes that decrease melanin production.

Seborrhea in dogs describes a defect in the keratinization of the skin or claws, which results in flaking skin. Primary seborrhea is inherited, while secondary seborrhea is caused by conditions including infection, allergies, or hormonal conditions.

Separation anxiety occurs when a dog develops a disproportionate fear or agitation in response to being separated from their owners or housemates.

Shaker syndrome describes a sudden onset of full body tremors in dogs. This common condition is thought to be immune mediated, but the exact cause is unknown.

Sialocele describes the leakage and accumulation of saliva in the tissues surrounding the salivary gland. Dogs with a sialocele present with a firm, painful swelling around the head and neck, which sometimes fluctuates in size.

Skin abscesses are a common condition in dogs caused by the introduction of bacteria under the skin as the result of a puncture wound. Once bacteria enter under the skin, they cause the tissue to swell, leading to pain, discomfort, and the production of pus.

Skin tags in dogs are benign masses arising from a small area of skin. They usually have a stalk and can be quite long.

Sleep aid toxicosis is a form of poisoning due to overdose or incorrect administration of benzodiazepines.

Snail and slug bait poisoning (metaldehyde toxicosis) occurs when dogs ingest a toxic amount of these pest control baits, which typically contain the toxin metaldehyde.

Rhabdomyosarcoma is a rare, malignant tumor of the striated (skeletal) muscle in dogs.

Soft tissue sarcomas are a common condition in dogs; they are a group of tumors which develop in the soft tissues, especially the chest, legs, or abdomen.

Solar dermatitis is a condition caused by exposure to UV rays, which leads to irritated skin, rashes, and potentially cancerous growths.

Squamous cell carcinoma (SCC) is a malignant tumor formed of keratinocytes, a type of skin cell. SCCs are often characterized by the location of the tumor (e.g. oral, digital, etc.).

Peptic ulcers are open, painful sores inside the lining of the digestive tract. Severe ulcers can perforate the stomach, leading to life threatening sepsis or peritonitis.

Helicobacter is a type of bacteria that can cause stomach infections in dogs. The precise pathogenic nature of the infection is currently unknown, and the presence of Helicobacter bacteria in the animal's stomach is not definitely linked to gastrointestinal symptoms

Stomatitis is a broad definition of inflammation of the gums and mucous membranes of the mouth. Refers to serious cases of gingivitis, periodontitis, pharyngitis, that include widespread irritation and ulceration of the tongue, gums, back of the throat, and palate.

A stroke, or cerebrovascular accident in dogs (CVA), is when there is a loss of blood flow to part of the brain, which damages brain tissue. There are two mechanisms of stroke: obstruction (ischemic) or rupture (hemorrhagic) of the blood vessels of the brain; ischemic events are more common in dogs.
