The reflex can be blocked by intravenous injection of an anti-muscarinic acetylcholine (ACh) antagonist, such as atropine or glycopyrrolate. If bradycardia does occur, removal of the stimulus is immediately indicated. This often results in the restoration of normal sinus rhythm of the heart.
Bradycardia can also result from the inhibition of the flow of action potentials through the atrioventricular (AV) node. While this can be normal in young patients due to excessive vagus nerve tone, symptomatic bradycardia due to AV node dysfunction in older people is commonly due to structural heart disease, myocardial ischemia, or age-related ...
It mostly affects young to middle-aged female dogs, [9] as the average age at diagnosis being four years old (although it has been found in puppies and dogs up to twelve years old). About seventy percent of dogs that are diagnosed with hypoadrenocorticism are female. [9] Hypoadrenocorticism is still relatively uncommon or underdiagnosed in dogs.

Individual dogs of any breed can have a profound reaction characterized by hypotension, especially if there is an underlying heart problem. In giant-breed dogs and sighthounds, the sedative effects of acepromazine may last for 12–24 hours, which is much longer than the usual 3–4 hours. [16] [20]
As more cases of a mysterious, potentially fatal respiratory illness in dogs are reported, dog parents are taking extra precautions. As more cases of a mysterious, potentially fatal respiratory ...
Neurogenic shock is a distributive type of shock resulting in hypotension (low blood pressure), often with bradycardia (slowed heart rate), caused by disruption of autonomic nervous system pathways. [1] It can occur after damage to the central nervous system, such as spinal cord injury and traumatic brain injury.
But while kennel cough clears up after 7 to 10 days, this new illness lasts weeks and sometimes leads to acute, or even fatal, cases of pneumonia. ... the onset of pneumonia in dogs can be treated ...
