Understanding Canine Blue Eye Disease: Causes and Preve

Certainly! Here's a revised version of the text with enhanced clarity, precision, and a more engaging, humanized tone:

Primary Symptoms:

Canine infectious hepatitis manifests in two distinct types: hepatitis and respiratory. These types exhibit varying symptoms.

Hepatitis Type Symptoms:

1. Dogs with hepatitis exhibit a poor mental state, a significant decrease in appetite, and a fever ranging from 40 to 41.5 degrees Celsius, which can last for 2 to 6 days, often showing a characteristic "saddleshaped" fever curve.

2. They may become excessively thirsty and drink water frequently, often dipping their front paws into water bowls. They may also suffer from conjunctivitis and excessive tearing.

3. Within 2 to 3 days of onset, the dogs' lower jaw and limbs may swell significantly, their abdomens may enlarge, and they may experience pain upon palpation. The mucous membranes may become pale, and one or both eyes may have cloudy corneas, which usually resolves in 6 to 8 days, leading to the nickname "blue eye disease."

4. Some dogs may experience bleeding gums, enlarged tonsils, and submandibular swelling, as well as poor blood coagulation. Some may also suffer from prolonged coma and seizures. Acute cases often result in death within 1 to 2 days of the onset of high fever.

Respiratory Type Symptoms:

1. Dogs with the respiratory type may have a prolonged high fever, increased pulse and breathing rate, and a transition from dry cough to mucopurulent or purulent nasal discharge.

2. Enlarged tonsils and pharyngitis may be present.

3. Some dogs may exhibit muscle tremors, vomiting, and diarrhea with mucus.

Diagnosis Key Points:

1. Canine infectious hepatitis can affect dogs of any age, though it is more common in puppies under one year old.

2. Dogs with the disease often display blue eye symptoms, mild jaundice, and poor blood coagulation.

3. Enlarged tonsils and lymph nodes throughout the body, excessive thirst, and increased water intake are common. Some dogs may suddenly die.

Treatment:

The general principle of treatment is as follows:

In the early stages, administering high doses of hyperimmune serum is recommended.

In the middle stages, intramuscular injections of broadspectrum antibiotics can help prevent secondary infections, while the antipyretic drug Wen'ao can be given orally.

For dogs with cloudy corneas, the use of Landoqing eye drops can be effective for treatment.
