There are three stages of rabies symptoms.
Prodromal stage: This stage usually lasts for 2 – 3 days. Dogs become nervous and may avoid contact with people. They often run a fever. They will lick the site of the bite excessively.
Furious stage. Lasts between 1 – 7 days. Dogs become irritable and aggressive. They are hypersensitive to auditory and visual stimuli.
Paralytic stage. Nerves of the head and neck are affected. The dog becomes unable to swallow and so begins to salivate and drool. Dogs may make choking sounds and it may seem as if something is lodged in their throats. Labored breathing and dropping of the jaw occur as the muscles of the diaphragm and face become more and more paralyzed. The dog will get weaker and weaker and eventually die of respiratory failure.
