my dog is 2 years old. he is a german shepherd. and he's been a very good dog until for some unusual reason when i woke up there was dischrge all around him in a puddle. there was a yellow thick texture with water on the floor. i m not sure what may have caused it but a few days before we fed him steamed beef...was this the cause of his leakage. and was it wrong to feed him this kind of beef or any meat? how can we stop him from leaving discharge drops all over the house.he also licks a lot down "there". is there any medication to stop all this?
