If a dog presented with a cough, which two systems would you check in the dog?

When a dog presents with a cough, it is essential to examine the respiratory and cardiovascular systems. The respiratory system is directly involved in the act of coughing, as it encompasses the airways, lungs, and associated structures that can become irritated or infected, leading to coughing. Common respiratory issues such as bronchitis, pneumonia, or tracheobronchitis can cause coughing, making this system a primary focus for assessment.

The cardiovascular system is equally important to consider, as it works closely with the respiratory system to deliver oxygenated blood throughout the body. Conditions such as congestive heart failure can manifest as coughing due to fluid accumulation in the lungs or pulmonary edema. Coupled with respiratory problems, cardiovascular issues can significantly contribute to the clinical presentation of a cough.

While other systems, such as gastrointestinal, nervous, endocrine, integumentary, or urinary, may have indirect effects or might be evaluated in a more comprehensive examination, they are not directly related to the primary concerns associated with a cough. Therefore, focusing on the respiratory and cardiovascular systems ensures a targeted and relevant assessment based on the sign of coughing.
