Which clinical signs suggest THC toxicity in a dog?

THC toxicity, or toxicity from tetrahydrocannabinol, the active component of cannabis, can produce a distinctive set of clinical signs in dogs. The presence of mydriasis (dilated pupils), bradycardia (slowed heart rate), ataxia (lack of voluntary coordination), and dribbling urine are particularly indicative of THC's effects on the central nervous system.

Mydriasis is common due to THC affecting neurotransmitter pathways, particularly those involving the autonomic nervous system. Bradycardia occurs as THC can impact heart rate regulation, potentially leading to an overall decreased heart rate. Ataxia signifies disruption in motor coordination, while dribbling urine points to possible impairment in bladder control, further reinforcing the neurological impacts of THC.

These signs collectively highlight the neurotoxic effects of THC, which can lead to altered mental status and motor function in dogs. Recognizing this constellation of symptoms is crucial for veterinarians in diagnosing and managing THC-related toxicity effectively. The other options, while they may be seen in different types of toxicity or health conditions, do not encapsulate the specific clinical manifestations associated with THC exposure.
