We are seeing a HUGE increase in the number of tick borne diseases in the last several years. Multimodal protection is key to prevention in your pet. It is important to consider year around flea and tick protection and the Lyme Vaccine as the number of cases are growing!
4, the number of dogs cared for by Upper Peninsula Veterinary Service who were lost to Lyme nephritis in the last 6mo.
A 13yo GSP, 7yo Golden, 6yo Border Collie & this week a 3yo Golden.
To transmit Borrelia burgdorferi (Bb), the bacteria that causes Lyme disease, a tick has to be attached for 18-24 hours.
It takes 2-5 months from infection of Bb to manifest into nephritis.
When we test in-office for Lyme disease, we're actually detecting antibodies. Antibodies are activated to neutralize and bind to viruses and bacteria (like Bb) and prevent them from entering the body and causing infection.
When our in-house Lyme pops positive, it tells us the body has been asked to make antibodies--indicating exposure.
Exposure doesn't mean infection. It is possible that the body cleared the bacteria. But to ensure it was able to tackle Bb, we send blood to an outside lab for a more specific test. If it was unable and there is indication of an active Bb infection we aid the clearance with antibiotic therapy and follow up with send out testing again in 6mo.
The Golden from this week had her last dose of Advantix II 2 months ago; her timeline indicates she was infected between Oct 2025-Jan 2026. Her owners thought she was protected.
25 years ago topical medications (Frontline, Advantage/Advantix, Vectra/etc) were the best we had and their intended target was primarily fleas. Unfortunately, 20 years later, our tick population has exploded and although fleas & ticks (& lice & mites) are in the same family, topicals are poorly effective against ticks.
Sadly, no medication is able to be guaranteed 100% protective. But less so are products that claim to kill kicks naturally or those which can be purchased over the counter at your local feed store.
At UPVS we recommend layered protection:
1. Tick checks--if you see them, remove & destroy.
2. Year-round Veterinary APPROVED protection-- there is NO safe season. Ticks don't care about snow or negative temps. They drop off their overwinter hosts (deer, rabbits, rodents, etc) and take up residence in a new environment.
3. Vaccination-- certainly helpful but cannot be relied on a sole method of protection.
The owner of this week's Golden gave me permission to share her case--she is heartbroken--but hopes by doing so, she can help bring awareness to the seriousness of tick borne diseases...
