What are the signs if a greyhound is ill?

Signs that a greyhound may be ill include lethargy or decreased activity, loss of appetite, unusual vocalizations, and changes in behavior or temperament. Additionally, look for physical symptoms such as vomiting, diarrhea, coughing, labored breathing, or signs of pain like whimpering or reluctance to move. Changes in drinking habits or difficulty in urination can also indicate health issues. If any of these signs are observed, it’s important to consult a veterinarian promptly.
