P.E.I. vet seeks puppies to be part of Lyme disease study

A veterinarian on P.E.I. is looking for puppies on P.E.I. to be part of a lifetime study to better understand their risk for developing Lyme disease and another disease called leptospirosis.

"Our hope is by following a group of young dogs through the course of their life that we would be able to answer some of these questions as far as how are they exposed to some of these diseases," said Dr. Michelle Evason, who teaches at the Atlantic Veterinary College in Charlottetown.

Not only are we asking people to be involved, we're asking people to stay involved. Dr. JasonStull, veterinarian

"And perhaps even more importantly what can we do to prevent them."

Lots of unknowns

Evason saidone of the challenges is all of the unknowns around Lyme disease, both in dogs and humans.

"We just don't know a lot about it," said Evason.

"This is a new condition for us over the past five to six years and on the Island itself, finding more of these ticks that carry Lyme disease is new."

When a dog tests positive for Lyme disease, she said,there are still lots of questions.

"We don't know if that then means they are going to develop severe clinical signs associated with Lyme diseaseand if we should be treating them with antibiotics, yes or no," Evason said.

"And it may be different from Lyme disease or other tick-borne diseases in other places."

100 puppies wanted

The study started a year-and-a-half ago in Ontario, where more than 200 puppies are now enrolled.

Evason launched the study in Atlantic Canada this summer and now has 30 puppies signed up, including 10 on P.E.I., with a target of 100 in the region.

Her vet students and co-researchers visited all the veterinary clinics on the Island in June and to date seven clinics have enrolled puppies.

The vet clinics collect blood samples from each of the puppies, then samples will be collected annuallyfor the lifetime of the dog.

Pet owners are also asked to fill in a questionnaire.

'Big concern'

In Atlantic Canada, Evason also added leptospirosis to the study.

"That's a really big concern and a fairly recent one again here in Atlantic Canada," Evason said, pointingto an outbreak last year in Halifax and surrounding areas.

"We know that it's a disease that can be spread from animals like raccoons and rats that shed it in their urine," Evasonsaid.

"Then dogs that splash through a puddle that has been contaminated with that urine can contract leptospirosis and become very ill."

Lifetime study

Dr. Jason Stull is a veterinary epidemiologist and co-author of the study in Atlantic Canada.

"This is a really challenging type of research to do because not only are we asking people to be involved, we're asking people to stay involved," Stull said.

"You don't see a lot of these types of studies occurring in veterinary medicine but I think it's one that if we want to answer these types of questions, this is the way we do it."

Owner concerns

Susan Tweel is eager to hear more about the research, to help her decide what she needs to do to protect eight-month-old Lucy.

"There was no question that I wanted her protected against Lyme disease so she takes a monthly medication for that," Tweel said.

"The veterinarian didn't necessarily recommend that she needed to be vaccinated for leptospirosis but we travel a lot off-Island where there are concerns about that, so I wanted to make sure she was covered."

Evason saidthe goal is to follow the dogs for their lifetime, with updates along the way. She and her co-researcher have already presented the findings of their baseline study in Ontario at two conferences this year.
