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.
Congestive Heart Failure Can Cause Dog Respiratory Symptoms. One reason for heavy dog breathing is congestive heart failure. Congestive heart failure occurs when the heart, damaged by poor diet or genetic abnormalities, fails to pump an adequate amount of blood through the body. This leads to fluid retention in the lung and body cavities.
