Yesterday, my GSD got a hold of 3 of my ducks and tore their necks open bad. The wounds are deep, muscle exposed, punctures, skin abrasions. I have flushed them well, cleaned with betadine, and applied FuraZone cream, which I mixed with sugar to help with granulation of the tissue. That has worked like a miracle, and the wounds themselves are healing rapidly. However, my male Ruen, Sarge, is lethargic. He is inside on cage rest and will not stay out of his water bowl, He drools a lot when he drinks, and is not eating very much. My concern is that he may be fevered, or have internal injuries. How can I tell? And how do u treat a fever in a duck? I cannot get to a feed store or vet, and must home treat.
