Modern thought often places fruits and vegetables at odds with each other. A food can belong to one but not both. Botanically speaking, a fruit develops from the wall of a plant's ovary and encases the seeds, so back in 1893, John Nix was right: Botanists consider tomatoes a fruit, not a vegetable.
Upper Respiratory Tract Infection in Dogs. Upper respiratory tract infections in the dog are most commonly due to bacteria and viruses. Until recently most clinicians assumed that dogs with acute onset nasal discharge, conjunctivitis, sneeze and cough had âkennel coughâ caused by Bordetella bronchiseptica.
Other causes of coughs. Although uncommon, tuberculosis does affect dogs and can cause upper respiratory symptoms. The cough associated with this bacterial infection is moist and productive; dogs may hack up bloody sputum, and suffer from labored breathing. Diagnosis is by x-ray of the lungs.
