My dog yelps when I touch its neck, and also when it lowers its head

If a dog yelps when its neck is touched or when lowering its head, it is likely due to pain. Possible causes include cervical problems such as cervical spondylitis or nerve damage, wounds on the neck or head, or bone spurs. These cause screaming when moving.

The owner can first check the body; if no external wounds, lumps, or cysts are found, take the dog to the vet for a full check such as X-ray or CT. For now, avoid moving the dog unnecessarily and, after diagnosis, choose conservative or surgical treatment.
