Atlantoaxial (AA) luxation is a condition in which instability, or excessive movement, is present between the first two vertebrae within the neck. This spinal disorder is most commonly seen in young, small breed dogs, such as Toy Poodles, Miniature Poodles, Yorkshire Terriers, Pomeranians, and Chihuahuas. Less commonly, however, large breed dogs and even cats can be affected.
Atrial fibrillation describes very rapid contractions or twitching of the heart muscle, specifically in the atria. Most of the time, atrial fibrillation in the dog occurs secondary to heart disease. Sometimes, in large breed dogs, atrial fibrillation will occur as a primary heart problem.
AV valve dysplasia describes a developmental malformation of the mitral or tricuspid valve, and may be referred to by the specific valve that is affected.
AIHA or IMHA is a life-threatening condition which may occur as a primary condition or secondary to another disease. Most dogs with AIHA have severe anemia, their gums will be very pale, they will be listless and tire more easily, be anorexic and will have increased heart and respiration rates. Diagnosis involves CBC, biochemical profiles, urinalysis, and X-rays or ultrasound of the abdomen and chest. Treatment may involve blood transfusions and other medications over a prolonged course of time. The prognosis may be better if an underlying cause can be identified.
The term autoimmune is a confusing one. Our bodies have an immune system that protects us from foreign invaders that can cause disease and infection; however, if you have an autoimmune disease, your immune system attacks itself by mistake, causing illness.
Bacterial pneumonia is an inflammation of the lung usually caused by bacterial or viral infection but can be caused by inhalation of an irritant. Typical signs of bacterial pneumonia include fever, difficulty breathing, lethargy and coughing. As these can also be caused by other disease, diagnostics include a full physical exam, blood work, radiographs, and may also require bronchoscopy with sample collection for cytology and bacterial culture and sensitivity. Treatment includes the use of one or more antibiotics that ideally would be selected using the results of a culture. Affected dogs may also require hospitalization and supportive care including intravenous fluids. Prognosis is good to guarded depending on the presence of predisposing factors.
Bandages or splints may be necessary at times if your dog has a wound or a broken bone. Bandages can be applied to the head, neck, chest, tail, or lower legs of a dog. Splints are usually applied below the knee on the back leg or below the midpoint of the humerus on the front leg. Home care is very important and you will need to monitor for changes closely. Your veterinarian will give you more specific directions for the length of time that your dog has to be bandaged.
Bite wounds are a common injury veterinarians see. If left alone, wounds have the potential to become more complicated, as they are likely infected and delaying treatment only makes it worse. Antibiotics, pain medications, and stitches may all be involved in the post-bite wound care.
Bladder stones are rock-like formations of minerals that develop in the urinary bladder. The most common signs that a dog has bladder stones are hematuria and dysuria. Bladder stones can develop within a few weeks or they may take months to form. Most bladder stones are visible on radiographs or an ultrasonic bladder examination. There are three main treatment options for bladder stones: 1) surgical removal; 2) non-surgical removal by urohydropropulsion, or 3) dietary dissolution. Prevention is possible in some cases, depending on the chemical composition of the stones.
Blepharitis means inflammation of the eyelid and can affect one or both eyes. The affected eyelid will usually be red, swollen, and itchy. Any condition that can cause irritation of the eyelids can lead to blepharitis. Common causes of blepharitis include congenital abnormalities, allergies, infections, tumors, and occasionally other inflammatory disorders. Your veterinarian will conduct an eye examination to determine the extent of the eyelid involvement. Specific treatment for blepharitis will depend on the underlying cause of the disorder and the prognosis depends on the cause.
