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.
Sometimes smelling the ground or rolling a ball around with his nose can cause a dog to pick up debris that can adhere to nose and dry-up. Illnesses like distemper, parvovirus, allergies, or an upper respiratory infection can cause a dog's nose to become runny, and the mucous build-up can become dry and crusty. Conditions like lupus and hypothyroidism can cause crusting of the nose as well.
