Knowing how your greyhound behaves when he is healthy can prevent some emergencies. If your ex-racer greyhound does show any of the following symptoms, call your veterinarian immediately for help or so the vet can be prepared, if needed, for your greyhound’s arrival:
- Any loss of appetite that continues for 24 hours. 
- Vomiting or diarrhea that persists for more than 24 hours, or any vomiting or diarrhea in a dog more than eight years of age. 
- Symptoms of bloat, such as unsuccessful attempts to vomit, rapid shallow breathing, a distressed appearance, and a painful or enlarged abdomen. 
- A first seizure, recurrent seizures, or any seizure that lasts more than three minutes. 
- Body temperature above 104 degrees or below 100 degrees. 
- A serious fall or blow to head, chest, or abdomen even if there is no apparent injury; any injury to the eye, no matter how minor; or any encounter with a moving vehicle. 
- Any open wound or injury in which bleeding continues for more than five minutes, despite your efforts to control it. 
- Difficulty breathing. 
- Collapse or unconsciousness. 
- Snake bite. 
- Heatstroke. 
- Poisoning. 
- Burns, no matter how minor. 
- Straining or difficulty urinating or defecating.
