Diagnosis differential diagnosis causes of cough. Causes of breathlessness. buy viagra cheap Causes of exercise intolerance/syncope: infectious tracheobronchitis ('kennel cough' ), especially in dobermann. Chronic bronchitis. Degenerative mitral valve disease. buying cheap viagra online uk Degenerative tricuspid valve disease. Pneumonia. Bronchopneumonia. Eosinophilic bronchopneumopathy ('allergic lung disease'). Sequelae prognosis classic form boxer: may survive months. daily viagra insurance coverage Giant breeds can usually maintain quality of life for 3-6 months. Dobermann: generally <6 weeks, rarely >6 months survival after onset of signs. Pimobendan therapy may prolong survival. Some cocker spaniel: >2-8 years. Giant breeds: may survive several years from onset of dysrhythmias but poor prognosis once congestive signs develop. viagra online canada reviews Ventricular dysrhythmias risk of sudden death even with anti-dysrhythmic therapy. Expected response to treatment control of congestive signs: decreased cough/breathlessness. Ascites. Restlessness. Increased appetite/weight gain. Exercise tolerance. Decreased ventricular rate, ie atrial fibrillation to <160 bpm. generic viagra canada Control of ventricular dysrhythmia. Normal or slightly elevated blood urea and creatinine levels. Reasons for treatment failure standard. Relentless progression of disease process, eg congestive signs, dysrhythmia. Development of an arrhythmia, eg atrial fibrillation and ventricular tachycardia. Complications due to concurrent disease, especially renal disease, hypothyroidism. Digoxin toxicity or other intolerance of medication, eg anorexia, diarrhea.
