spleen cancer in dogs |

The source of the disease is unknown, with the Environment Agency ruling out any chemical contamination in water supplies. Experts believe the disease is “very similar” to Alabama Rot, thought to be related to a toxin produced by E. Coli bacteria. However, no evidence of this has been found after no signs were shown on the infected dogs.
Prostate cancer* is rare in dogs and occurs in both intact and neutered animals. It is malignant. The most common type is adenocarcinoma. Signs include blood in the urine and straining to urinate or defecate. It most commonly spreads to bone and the lungs.[161]
Eye diseases are common in dogs. Cataracts, canine glaucoma, and entropion are seen in dogs. Canine-specific eye diseases include progressive retinal atrophy, Collie eye anomaly, sudden acquired retinal degeneration, and cherry eye. Injury to the eye can result in corneal ulcers.
Laboratory tests include blood tests (e.g., to detect a low white blood cell count) and other tests to detect the virus (e.g., ELISA, electron microscopy). ELISA (enzyme-linked immunosorbent assay), which detects the presence of the virus in stool, is used most often. In some cases, recent immunization with the live virus can produce a false positive test result.
The best way to diagnose a worm problem is with a visit to the vet. Treatment depends on which type of worm your dog has, but generally includes an oral medication and may require follow-up. Don’t try treating worms yourself: A medication that kills roundworms, for example, doesn’t kill tapeworms.
People exposed to Salmonella might have diarrhea, vomiting, fever, or abdominal cramps. Infants, elderly persons, and those with weakened immune systems are more likely than others to develop severe illness.
Nuclear sclerosis is a consistent finding in dogs greater than seven years old. Nuclear sclerosis appears as a bilateral bluish-grey haziness at the nucleus, or center of the lens,[62] and has little effect on vision.[66] This is may be confused with cataracts.[67]
Pyometra is an infection of the uterus. It is a common and potentially fatal condition in dogs. The main risk period for a female is for eight weeks after her peak standing heat (or estrus cycle) has ended.[6]
Corneal dystrophy is a condition characterized by bilateral, noninflammatory opacity of the cornea. It appears as grayish white lines, circles, or clouding of the cornea. Corneal dystrophy can also have a crystalline appearance.[62]

Being familiar with these common dog health issues should help you know which ones you can treat yourself, and when it’s time to see a vet. If you find yourself visiting the vet often perhaps pet insurance is something you should consider. It can greatly reduce your out-of-pocket cost when visiting your veterinarian. Check out our Pet Insurance Comparison to see which pet insurance providers might be a good fit for your family.
What’s true for humans is also true for dogs. Of-the-moment food regimens—like the wolf diet, raw-food craze, or grain-free eating—aren’t worth the money or time. Yes, they can provide balanced meals, and thus aren’t harmful, Case says, “but there is no demonstrated evidence of their health benefits” over other more-standard diets. Tip: Want to provide your pooch with raw food? Be sure it’s pasteurized to ensure safety.
How to treat: Vaccines can be administered regularly to prevent some types of kennel cough. If your dog catches kennel cough you should take him to your vet where he might be prescribed medications that will speed up the recovery process. Keep your pup away from other dogs (especially in public places where the illness can spread rapidly), and give him lots of rest. Once you see signs of recovery, take him for regular walks until he is himself again.
Orthopedic diseases in dogs can be developmental, hereditary, traumatic, or degenerative. Because of the active nature of dogs, injuries happen frequently. One of the most common of these is an anterior cruciate ligament injury, a condition which often requires surgery. Bone fractures are a frequent occurrence in outdoor dogs due to trauma from being hit by cars. Degenerative joint disease is common in older dogs and is one of the most likely reasons for prescription of non-steroidal anti-inflammatory drugs.

Older, small breeds of dogs are prone to congestive heart failure due to degeneration of the mitral valve. This condition is known to be inherited in Cavalier King Charles Spaniels. Degenerative valve disease is the most common form of heart disease in dogs.[23] Mitral insufficiency leads to turbulent blood flow and increased pressure in the left atrium. This causes increased pressure in the pulmonary blood vessels and pulmonary edema (a build-up of fluid in the lungs). Decreased output of blood by the left ventricle causes the body to compensate by increasing sympathetic tone and activating the renin–angiotensin–aldosterone system (RAAS). Increased sympathetic tone leads to increased peripheral vascular resistance and increased heart rate and contractility of the heart muscle. Chronic elevation of sympathetic tone damages the heart muscle. Activation of the RAAS results in increased retention of water and sodium by the kidneys, vasoconstriction, and other effects that result in increased blood volume. It also results in an increase in diastolic pressure and leads to pulmonary edema. Treatment for congestive heart failure has historically focussed on two types of drugs that address these concerns: diuretics (especially furosemide), which decrease blood volume, and ACE inhibitors, which interrupt the RAAS. Recently, pimobendan – which increases the force with which the heart muscle contracts, and is also a vasodilator – is being more widely used in the treatment of congestive heart failure caused by valvular disease. A major veterinary study, called the QUEST study (QUality of life and Extension of Survival Time), published in September 2008 found that dogs with congestive heart failure receiving pimobendan plus furosemide had significantly better survival outcomes than those receiving benazepril (an ACE inhibitor) plus furosemide.[24] However, ACE inhibitors and pimobendan have different mechanisms of action, and many veterinary cardiologists recommend they be used concurrently. Within the past decade, a new surgical technique has been developed for mitral valve repair that replaces or strengthens the mitral valve chords with polytetrafluoroethylene (PTFE) prostheses and tightens the mitral valve ring to reduce or eliminate regurgitation.[25][26][27][28]
Pick a dog that is bright, alert, and playful. Dogs and puppies should have shiny, soft fur that is free of stool. Signs of illness in a dog include appearing sluggish or depressed, having diarrhea, abnormal breathing, and fluid running from its eyes or nose. Make sure to take your new dog or puppy to the veterinarian within a few days to a week after adoption for a health visit.

Keeping your dog away from tick-prone areas and checking your dog for ticks are always good ideas, but preventative tick medicines are the most effective way to prevent Lyme disease, and other tick-borne illnesses.
Heartworm is a parasitic worm that lives in the heart and pulmonary arteries of an infected animal. The worms travel through the bloodstream—harming arteries and vital organs as they go—ultimately completing their journey to the vessels of the lung and the heart chamber about six months after the initial infection. Several hundred worms can live in one dog for five to seven years.
Degenerative (myxomatous) mitral valve disease* is a common cause of congestive heart failure in dogs, especially small, older dogs.[48] The leaflets of the valve become thickened and nodular, leading to mitral valve regurgitation and volume overload of the left side of the heart. Cavalier King Charles Spaniels and Dachshunds have an inherited form of this disease.[49]
“We would also encourage all vets and owners to work with David and his team at Anderson Moores so we can have a clear picture of confirmed cases in the UK, to help prevent more dogs falling victim to this terrible disease.”
Intussusception* is characterized by telescoping of one part of the gastrointestinal tract into another part, forming an obstruction. It is most common in dogs six to eight months old. Surgery is necessary for treatment.[147]
Eye proptosis is a condition resulting in forward displacement and entrapment of the eye from behind by the eyelids. It is a common result of head trauma in dogs. Most commonly it occurs in brachycephalic (short nosed) breeds.[62]
Sensitivity to anaesthesia can occur in any breed, but sighthounds have been the breeds most documented to have anesthetic concerns. Sighthounds are known to have prolonged recovery times from ultra short-acting thiobarbiturates such as thiopental.[164]
Leishmaniasis is a protozoan disease of people and animals. It is transmitted by sandflies and is uncommon in North America. The two forms of the disease are visceral and cutaneous. The cutaneous form of leishmaniasis is most common in people and appears as one or more painless ulcers on the skin. Visceral leishmaniasis is less common and is characterized by fever, weight loss, enlarged spleen, and anemia. Dogs can develop both forms at the same time and have a variety of symptoms.
Pericardial effusion* is a collection of fluid in the pericardium. It is usually serosanguinous (bloody fluid). Serosanguinous accumulation can be caused by cancer, usually hemangiosarcoma or a heart base tumor, idiopathic pericarditis. Rare causes include trauma, clotting disorders, and left atrial rupture. Serous accumulation is rare and caused by heart failure, peritoneopericardial diaphragmatic hernias, uremia, pericardial cysts, or hypoalbuminemia. Rarely pericardial effusion can be caused by infection and consist of pus. An echocardiogram should be done prior to draining the fluid, if possible, to identify the cause (e.g., tumor). Drainage of the fluid (pericardiocentesis) relieves the clinical signs and, in the case of idiopathic pericarditis, can be curative.[49]
Laryngeal paralysis is unilateral or bilateral paralysis of the larynx. In dogs it can be congenital, seen in the Bouvier des Flandres, Bull Terrier, Dalmatian, Rottweiler and Huskies, or an acquired, idiopathic disease, seen in older Labrador Retrievers, Golden Retrievers, St. Bernards, and Irish Setters. Signs include change in voice and difficulty breathing.[61]
Sporotrichosis is a fungal disease caused by Sporothrix schenckii that affects both dogs and humans. It is a rare disease in dogs, with cat and horse infections predominating in veterinary medicine. The disease in dogs is usually nodular skin lesions of the head and trunk.[22]
Sudden acquired retinal degeneration (SARD) is a disease in dogs causing sudden blindness. It can occur in any breed. The cause is unknown, but possibly involves either autoimmune disease, a toxin, or Cushing’s disease. Symptoms include sudden permanent blindness, dilated pupils, and loss of the pupillary light reflex.[62]
Rarely, Capnocytophaga can spread to people through bites, scratches, or close contact from a dog or cat and cause illness. Most people who have contact with a dog or cat do not become sick. People with weakened immune systems who have difficulty fighting off infections (for example, people with cancer or those taking certain medications such as steroids) are at greater risk of becoming ill.
What to look for: If your dog is vomiting, there could be any number of causes. Generally speaking, it’s best to assess your dog’s behavior leading up to the vomiting to see if there might be a more serious issue. General vomiting, initially, is normal and could have been from something your dog ate.
Umbilical hernia* is a failure of the umbilical ring of the abdominal wall to close. They are very common and can be caused by genetics or by traction on the umbilical cord or by the cord being cut too close to the body. They are corrected by surgery.[160]
