Your Dog Got Bitten by a Rattlesnake. Do This Now.
The first 50°F weekend of the year, Rocky and I hit a trail we hadn’t touched since October. Fifteen minutes in, he was limping. A foxtail had already found its way between his front toes, sitting in dried grass I hadn’t even noticed, because I was still thinking in winter mode. New snow, ice melt, cold. Those were the hazards I’d been focused on for months.
Spring has its own playbook. And if you’re still running your winter protocol into mud season, you’re setting yourself up for exactly the kind of trailside mess I found myself dealing with that morning.
The short version: check paws at the trailhead before you start, after every creek crossing, and immediately when you get back to the car. Now here’s the full breakdown.
Quick Info
Hazard Peak Window Priority Foxtails / Grass Awns March–June (by region) High — can migrate into tissue Ticks March–November, peak April–May High — Lyme disease transmission Snowmelt chemicals February–April Medium — paw burns, ingestion risk Slick mud / wet rock March–May Medium — soft tissue injury Cold water streams March–May Low–Medium — hypothermia risk in small dogs Best paw protection: Dog boots for foxtail country; paw wax for chemical runoff and cracking Key gear add: Rain jacket for spring shower conditions Spring window: Most hazards peak in the 6–8 weeks between snowmelt and full summer
Winter is predictable. You know to watch for ice melt, cold exposure, and shortened daylight. Summer is mostly about heat management. Spring is neither: it’s a revolving hazard window where you can hit frozen ground, salty puddles from snowmelt runoff, early foxtail grasses, and active tick habitat all on the same trail, sometimes in the same mile.
I’ve talked to owners who nail their winter kit and summer kit but completely skip spring prep. Their dogs end up at the vet in April with either an infected foxtail wound or a tick-borne illness that started on what felt like a mild, easy hike.
The seasonal transition matters. Treat it as its own planning window.
Foxtails are the hazard most hikers underestimate until their dog has one. They’re the seed heads from wild barley and other grasses — small, sharp, and designed by nature to burrow forward through anything they contact. They don’t work back out. They migrate.
Paws are the most common entry point, specifically the skin between the toes. A foxtail that gets ignored for a few days can track upward into the paw pad, or — worst case — into the lymphatic system. The UC Davis School of Veterinary Medicine documents cases where foxtails migrated from paw entries to the lungs and spinal cord. That’s not fear-mongering. It’s why early detection matters.
What to do:
Rocky wears boots from mid-March through June on trails through dry grassy meadows. The alternative is standing over him with tweezers at the tailgate after every hike.
Tick populations peak in spring because the nymph stage — the smallest, hardest-to-see ticks — emerges when soil temps consistently hit 45°F. That happens well before your trail feels like “tick weather.” You’re often hiking in a fleece jacket. Ticks are already active.
Ticks can transmit Lyme disease in as little as 24–48 hours of attachment. The short window makes prevention far more effective than post-hike response.
Prevention approach:
If you find an attached tick, use fine-tipped tweezers, grip as close to the skin as possible, and pull straight out with steady pressure. Don’t twist. Mark the date and watch the bite site for 30 days. Any bullseye rash or sudden lethargy is a vet call.
This one bridges the gap from winter to spring. Ice-melt products — calcium chloride, sodium chloride, magnesium chloride — don’t disappear when snow melts. They pool in low spots, puddles, and trail edges where snowmelt collects. Your dog may be trotting through what looks like harmless standing water that’s actually a concentrated chemical runoff.
The exposure risk is dual: contact burns on paw pads, and ingestion when dogs lick their paws. Veterinarians confirm February through April as peak chemical burn season, particularly in areas with mixed winter/spring conditions.
What helps:
For trail areas that see heavy winter maintenance, the chemical window can extend well into April. If the puddles smell faintly chemical or have an oily sheen, treat them as contaminated.
Spring trails are often in the worst mechanical condition of the year. Freeze-thaw cycles churn the soil into deep mud. Rock surfaces that look manageable are coated in wet algae or thin frost in shaded sections. Dogs that charge confidently through all terrain suddenly wipe out on a muddy descent.
Soft tissue injuries — pulled muscles, strained tendons — spike in spring because both dogs and owners underestimate the traction difference. Rocky pulled his left shoulder on a wet granite slab in April last year. It looked completely dry from 20 feet away.
What helps:
Some trails simply shouldn’t be done during peak mud season. The damage to the trail surface is real, and a dog who’s sliding isn’t having a good time. Call it early without guilt.
This question gets searched constantly and the answers online are often muddled. Here’s the clean breakdown from someone who’s used both for multiple seasons:
Paw wax (Musher’s Secret and similar):
Dog boots:
The common mistake: using wax thinking you’ve handled foxtail protection. You haven’t. Wax is skin care. Boots are protection. They solve different problems and can be combined — wax under boots adds moisture protection while boots handle the mechanical hazards.
For spring specifically, I run wax on days I’m not using boots (mellow trails, low foxtail exposure) and boots on any trail through dry meadow grass or known foxtail habitat.

Spring-specific additions for the pack:
Rocky’s had a Ruffwear Overcoat for three years. Works fine. But Bravident released a jacket in February 2026 worth paying attention to: the DriftShell Dog Jacket, which uses PFC-free waterproof fabric and fully waterproof YKK zippers, a spec usually found only in technical human gear.
PFC-free matters because traditional DWR (durable water repellent) coatings contain per- and polyfluoroalkyl substances that accumulate in watersheds and wildlife. For dogs who hike near water sources, it’s a cleaner option. The 15,000mm waterproof rating handles sustained spring rain, not just light drizzle.
I haven’t personally put 100 trail miles on it yet. Rocky is my test dog for the spring season and the construction details are right. YKK waterproof zippers are what separate functional rain gear from gear that fails on day three.
If you’re already set on a rain jacket, no need to swap. If you’re buying new, the DriftShell is worth the look.
When you need a rain jacket:
Rocky (Australian Shepherd, good double coat) doesn’t need a jacket until temps drop below 40°F or conditions are wet AND cold. Your short-coated dog’s threshold is about 10°F higher than that.
Don’t skip this. The hazards don’t stop at the trailhead.
The whole routine takes 8–10 minutes. Rocky has learned to stand still for it — partly conditioning, partly because the paw wax application apparently feels good. I run the tick check while he eats his post-hike treat, which helps with the cooperation factor.
Some spring trail injuries look minor and aren’t:
For the rest — mild mud scrapes, temporary limping that resolves, surface foxtails you can see and remove cleanly — monitor and manage at home. The post-hike inspection routine catches most issues before they escalate.
If you’re doing technical routes this spring, review our off-leash hiking training guide before you go. Reliable recall is even more important when your dog is pushing through brush where you can’t see what they’re contacting.
Spring hiking is genuinely great. Crowds are down, temperatures are manageable, and dogs who were cooped up all winter come alive on trail. But the seasonal hazard profile is distinct from winter, and the gap between “winter mode” and “summer mode” is exactly when dogs get hurt.
The practical spring protocol: check paws before and after every hike, carry tweezers, get tick prevention sorted with your vet before March, and run boots through foxtail-risk terrain regardless of how mild the weather feels.
Your next step: look at the trails on your spring list and identify which ones pass through dry grassland or brush. Those are your foxtail-risk routes. Get Rocky — or your dog — fitted for boots before the season opens up, not after the first incident. The fitting and training process takes a few weeks. Start now.
