As the weather (slowly and inconsistently) gets nicer here in Ontario, dogs start to go swimming more. My dog, Ozzie (pictured below), is an embarrassment to the Labrador breed as he will not swim, but he’ll happily wade through water, as long as his feet don’t leave the ground (but he still manages to get

Rocky Mountain Spotted Fever: What Are The Signs?

Our emerging concerns about Rocky Mountain Spotted Fever (RMSF) in Long Point, Ontario, have led to a variety of questions from veterinarians and dog owners. (It’s also led to a lot of rumours, and sorting out what’s real illness vs internet chatter and hype is tough – but that’s another story.)
We’re still trying…
Update: Rocky Mountain Spotted Fever, Ontario

I recently wrote about a couple cases of Rocky Mountain Spotted Fever (RMSF) in dogs in Ontario. It’s not a disease we expect to find here, but we’re concerned about this tick-borne disease because it can be very nasty, and we do have the ticks for it. Ticks and the diseases they transmit are…
Rocky Mountain Spotted Fever, Ontario
I’ve heard of a few possible cases of Rocky Mountain Spotted Fever (RMSF) in dogs in Ontario in the past week. It’s pretty preliminary information, but it’s relevant to both dog and human health so it’s worth getting some information out about it now.

COVID-19 and Overdue Dog/Cat Vaccines, Part 4: Lyme disease
Lyme disease vaccine is a non-core vaccine, meaning it’s not needed for all dogs in all areas. It’s an effective vaccine, and I’d consider it a reasonable vaccine to give to dogs in (or visiting) higher risk areas, especially when there might be owner compliance issues with tick preventive medication. Available tick preventatives are very…
Asian Longhorned tick and the role of canine (and feline) surveillance
As the Asian Longhorned tick (Haemophysalis longicornis) continues to spread in the US, we wait for it to make an appearance in Canada. This “exotic tick” was introduced to the US from Asia possibly a while ago, but was only first detected in 2017 in New Jersey. It has since clearly established itself…
PetsAndTicks… New for 2019
I keep saying spring is approaching and I keep getting disappointed by the cold weather. But it’s going to happen soon, so we’ve been gearing up for tick season. There are a few new initiatives underway for tracking ticks and tickborne diseases in Canadian dogs and cats. Check out the recent post at PetsAndTicks.com for…
