Please choose the correct ending to complete the given sentence: Pets and Animals: [header] How to diagnose canine infectious hepatitis [title] Be aware of the signs of infection. [step] The first sign is a fever of 104f (40c) or over, which lasts for 1-6 days. The dog may also have sticky eyes, which is a very similar presentation to distemper.

Ending1: The reason the dog's nose may be pale is because saliva causes the nose hairs to sit in the bleeding fluids. Saliva helps to slow down the healing process, making it easier to see the infected material. Ending2: While not always obvious in dogs, look closely to the dog's face as the infected pus will look brownish and dark. It is the most common symptom for household infected dogs. Ending3: Dogs with ich usually become very ill very quickly and are extremely lethargic and lacking in energy, off their food, develop sickness and diarrhea, and then a raft of other symptoms. This varies slightly from distemper, where the symptoms tend to come on less quickly. Ending4: The dog may also have missing teeth, resulting in white patches on its head. It may also have possibly been infected with pancreatic lymph nodes, which only appear at night.
