If you’re a Mini Aussie owner, tick season is not just an inconvenience — it’s a real health conversation. And it’s one that deserves more thought than a monthly chew and a checkbox.
I’ve been raising Mini Australian Shepherds in Middle Tennessee for over 18 years. Tick exposure is part of life here. We border some of the densest tick habitat in the country — and the approach I take with my own dogs, and recommend to every BBA family, is not the one most vets default to.
This post is about prevention first, terrain-building as the foundation, and knowing exactly what to do when a tick finds your dog anyway.
“Most owners only focus on removing the tick. What happens after removal is where long-term resilience is built.”
The Warning Every Aussie Owner Needs to Hear First
Before we talk about prevention options, there is something specific to Australian Shepherds — Mini and standard — that most vets either don’t know or don’t think to mention.
Aussies carry a significantly elevated rate of the MDR1 (ABCB1) gene mutation — a genetic variant that affects the blood-brain barrier’s ability to pump certain drugs back out of the brain. In dogs with this mutation, some medications that are safe for other breeds can reach toxic levels in the nervous system.
The isoxazoline class of flea and tick preventatives — which includes NexGard, Bravecto, Simparica, Credelio, and Revolution Plus — work by targeting GABA receptors in insects. In dogs with the MDR1 mutation, these drugs can cross the blood-brain barrier more readily, with reported adverse effects including:
- ⚠Tremors and muscle weakness
- ⚠Ataxia (loss of coordination)
- ⚠Seizures
- ⚠Lethargy and behavioural changes
- ⚠Vomiting, hypersalivation
- ⚠In severe cases, death
Approximately 50% of Australian Shepherds carry at least one copy of the MDR1 mutation. Because this mutation is so prevalent in the breed — and because even a negative test doesn’t account for every variant — at Blue Buckaroo we recommend treating all Aussies as MDR1 affected as a precautionary standard. The risk is real enough that we won’t gamble on it.
Our recommendation: avoid isoxazoline-class preventatives for Aussies entirely and choose alternatives that do not carry this risk profile.
The Terrain-First Philosophy
Ticks don’t just bite any dog indiscriminately. Research and holistic practitioners consistently observe that dogs with strong immune terrain, low toxic burden, and a healthy microbiome are less attractive to parasites — and more resilient when exposure does happen.
Prevention isn’t just about repelling — it’s about building a dog that can handle exposure.
Natural Prevention Strategies That Actually Work
Natural prevention is a layered approach — repellents, environmental management, and a dog whose immune terrain makes them a less desirable host.
When Conventional Prevention Makes Sense
I’m not going to tell you that chemical preventatives are never appropriate. If you’re in a high-Lyme area, if your dog is immunocompromised, or if natural prevention alone isn’t sufficient — conventional options are sometimes the right call. What I ask is that you make that decision with full information.
- →Avoid all isoxazoline-class products for Aussies — NexGard, Bravecto, Simparica, Credelio, Revolution Plus. We treat all Aussies as MDR1 affected.
- →Consider topical Frontline (fipronil-based) if chemical prevention is needed — different mechanism, does not carry the same MDR1 risk profile.
- →Seresto collar (flumethrin/imidacloprid) is another option some integrative vets find acceptable — discuss with your vet.
- →Support the liver and gut around any chemical use — milk thistle, probiotics, real food.
- →Watch closely for adverse reactions in the 48 hours after any new preventative.
You Found a Tick. Now What?
Even with the best prevention in place, ticks happen. The priority when you find one is not panic — it’s response. The first 48 hours matter more than most owners realise.
The Forever Canine After The Bite™ guide is the most comprehensive tick response resource I’ve found. It covers the full 4-phase roadmap — immediate response, active support, gut restoration, and long-term immune strengthening — with dosing guides, herb protocols, and an 8-week monitoring tracker. This is the resource I recommend to every BBA family in tick country.
What We Do at Blue Buckaroo
Every BBA puppy family in tick-exposed areas gets our tick protocol as part of their go-home resources. Here’s the short version of what we do and recommend:
- ✓We treat all Aussies as MDR1 affected — no exceptions, regardless of test status
- ✓We do not recommend NexGard, Bravecto, Simparica, Credelio, or Revolution Plus for any Aussie
- ✓Terrain-first: real food, gut support, omega-3s, and medicinal mushrooms through tick season
- ✓Cedar or neem-based topical repellent before walks in tick habitat
- ✓Tick check after every outdoor exposure — ears, groin, armpits, between toes
- ✓Ledum 200C and olive leaf extract on hand at all times — start same day as any bite
- ✓Milk thistle seed in food through peak tick season as liver baseline
- ✓After The Bite™ guide in the go-home resources folder — know the protocol before you need it

Immediate response protocol, Lyme monitoring, liver + lymph support, gut restoration, herbal protocols, dosing guides, and an 8-week tracker. Don’t wait for a bite to figure out the plan.
