Animal hospital in Kelowna sees uptick in cannabis toxicity in dogs

According to Fairfield Animal Hospital, one of the most common presentations at the Emergency clinic is dogs that have ingested some form of THC. 

Lately, however, they’ve seen the number of cases go up even more. 

“It is not unusual to have several cases come in weekly. The Easter long weekend the clinic had a record number. 13 dogs were seen on emergency that were showing signs of a marijuana ingestion,” said Dr. Jennifer Watt from Fairfield Animal Hospital.

While legally ingested by many in Kelowna, the drug itself or the by-products made from the THC component is toxic to dogs. 

Dogs begin to show symptoms 30-90 minutes after consumption of THC, says Watt. 

The classic symptoms she pointed out include incoordination, listlessness, dilated pupils, slow heart rate, urinary incontinence, and a startle reaction (the dog appears drowsy but then over reacts to noise and touch). 

“Most of these cases resolve with time,” explains Watt. “The problem arises when the dog gets into a lot of THC.”

The severity depends on the type of drug and the individual dog, much like with people. 

Too much THC can lower the heart rate, blood pressure, and body temperature to dangerous levels and can cause a loss of consciousness. 

“If a dog gets into THC or is exhibiting symptoms of a drug ingestion it is important to get medical care for them,” Watt continues. “It is helpful for the relevant information to be given to the veterinary team. There is no judgement. There is a urine drug test that can give results in 30 seconds.”

If the ingestion has happened within 30 minutes, vomiting can be induced to get rid of material in the stomach and charcoal given to prevent absorption of any remaining drug. 

Once symptoms are shown an injection for nausea can be given since this is often a concern. If vitals are stable and the dog is still able to walk, drink, and eat they can be sent home for care. 
“If the dogs are not conscious or extremely sedated with a low blood pressure and a low body temperature they are admitted and treated with fluid support, supplemental warming, and close observation. In most cases the chance of a fatality is extremely small but possible,” Watt says. 

“Most cases of THC toxicity resolve within a short time. THC is stored in the fat deposits so the effects can last for days. Rest easy, there has not been any evidence that marijuana causes permanent effects in dogs.”

Watt adds that one thing to note is that THC edibles that are made with chocolate, nuts, butters, and oils can cause other issues. 

These ingredients affect the body in different ways and do require medical treatment. 

To avoid having to take your beloved pooch to the clinic, it’s best to keep your stash in a safe place.
