What is it called when a horse makes funny noise and its neck swollen?

It's impossible to say for sure what's wrong with a horse based on just a funny noise and swollen neck. These are both symptoms of various health issues, and it's important to consult a veterinarian for a proper diagnosis and treatment.

Here are some possibilities, but it's crucial to contact your veterinarian immediately:

* Strangles: A highly contagious bacterial infection affecting the upper respiratory system. Symptoms include a swollen throat, difficulty breathing, and fever.

* Abscess: A collection of pus that can occur in the neck due to infection.

* Laryngeal Hemiplegia: A condition affecting the larynx, which can cause a "roaring" noise.

* Trauma: A possible injury to the neck, such as from a kick or a bite.

* Other infections: Viral or bacterial infections can cause swelling and noise in the neck.

Remember: Never attempt to self-diagnose or treat a sick horse. Prompt veterinary attention is crucial for a speedy recovery.
