Veterinarians are advising pet owners to be vigilant about their surroundings after a little Chihuahua was sickened from a possible cannabis-infused edible it ate at a B.C. dog park.

Michelle Tuan says she took her Chihuahua-cross named 鈥淒orito鈥 to the Leigh Dog Park in Coquitlam, B.C. on Wednesday. Several hours after the visit, Tuan said she noticed her pet behaving strangely.

鈥淲hen I went to go pick him up, he was whimpering and crying out like he was injured,鈥 she recalled to CTV Vancouver on Friday.

Tuan said she grabbed a treat and tried to coax her dog to walk over to her.

鈥淗is whole body was kind of like curved,鈥 she said. 鈥淸He] was sort of walking almost sideways towards me. I don鈥檛 know how old he is because he is a rescue dog and I thought maybe he was having a stroke.鈥

Dorito didn鈥檛 in fact suffer a stroke, but it may have ingested cannabis. That鈥檚 according to the veterinarian Tuan brought her dog to the day after the visit to the dog park.

Tuan said the veterinarian told her that Dorito had tested positive for THC, the psychoactive ingredient found in cannabis, and the dog likely ate a pot-infused edible left behind at the fenced-in park.

Veterinarian Fraser Davidson said his clinic has noticed an increase in dogs coming in regularly that have ingested marijuana. He said the main symptoms for dogs include stumbling, not responding, and falling over.

鈥淔ortunately the signs, while they鈥檙e disturbing, don鈥檛 tend to be life-threatening,鈥 he explained. 鈥淚t鈥檚 more just the animals going through a miserable time. I think the public just need general education that it鈥檚 not just children that are at risk.鈥

Tuan said her dog was given a charcoal solution to remove the THC from its system. Although Dorito is feeling much better, Tuan said she鈥檚 still shaken from the incident.

鈥淚 don鈥檛 think we鈥檒l be going back to a dog park for a long time,鈥 she said.
