Thank you for your question.Anorexia and lethargy are non-specific signs of the young buck and can be seen associated with a wide range of conditions. Therefore, getting a temperature would be a good start since the presence of fever would potentially cross some of our concerns off our differential list.Now to help us determine if he could have a urinary blockage:Can you tell me when you last saw him urinate?
Is he dribbling urine?Is he straining, flagging his tail, or stretching out his front and hind legs or positioning to urinate but not passing anything?
Does his belly look distended or bloated?Is he collapsed, grunting, grinding his teeth, showing increased vocalization or kicking at his side (essentially is he in pain)?Otherwise, how long has he had diarrhea?Can you describe what he is passing?
Sorry, I didn't get back to you, he is now fine... he did not have a temp and no sign of urinary blockage
