My german shepard started drouling a lot of white phelm. He looks sick and is not barking like he usually does. He is 9 months old. A relative thought that he could have eaten a frog. He is not wanting to eat very well. He is up to date on his shots.

Have you thought about taking him to the vet? It could be anything from a viral infection to something be lodged in his throat. Could even be something internal like kidneys or liver. Best not to wait and see. Make an appointment with your vet.
