If exposed to antifreeze he won't survive, but if it is caused but the heat and dehydration he has a good chance to recover funtion with aggressive treatment. So keep him hydrated, monitor electrolytes and perhaps he can come thru. Best of luck. If he can return to normal I am sure he will find his forever home. Best to you.
