Outside of our regular business hours, we will refer you to one of two excellent emergency vet and critical care hospitals that are open 24 hours a day. If your pet seems ill or uncomfortable, we encourage you not to wait until we are open as your pet may continue to get worse. At the very least, please call one of the animal emergency clinics for their advice as to whether they feel a visit is recommended? The name of the emergency facilities is Blue Pearl and they have a location in Skokie (847) 673-9110 and Northfield (847) 564-5775. We will receive reports from them the next morning if they have seen and treated your pet so we will know what ongoing care or follow-up is necessary.
