Kong has weakness in his legs, cloudy brown pee, very bad diarrhea, he has no appetite, an he has blood in his slobber
I'm really sorry to hear that Kong is experiencing these symptoms. These symptoms could indicate a serious underlying condition such as a severe infection, organ dysfunction, or poisoning.
While you prepare to seek immediate veterinary care, make sure he has access to fresh water at all times. Hydration is crucial, especially with diarrhea, as dehydration can worsen his condition. Secondly, keep him in a quiet and comfortable place where he can rest without being disturbed. Lastly, closely monitor his symptoms, noting any changes or additional symptoms that may develop.
Given the severity of his symptoms, it's essential to get him to a veterinarian as soon as possible. Kong's symptoms are long-standing, so I recommend testing to determine the exact cause and treat accordingly.
If you have any further questions, please don't hesitate to ask. Thank you.
