Spring and summer mean one thing in a lot of pet households: travel. Dogs hanging their heads out windows. Cats in carriers on the back seat. Stops at new parks, trails, and campgrounds.
Travel changes everything about your pet’s environment in a short period of time. New smells, new sounds, disrupted routines, unfamiliar terrain, and temperature swings across regions can all combine to create situations you wouldn’t encounter in your own backyard. At Tell Tail Veterinary Urgent Care, we see a reliable spike in travel-related cases every spring and summer. Here’s what to watch for and how to handle it when something goes wrong.
Heat in the Car: Still the Leading Killer
Even experienced pet owners underestimate how fast a parked car becomes dangerous. On a 75°F day with mild cloud cover, the interior of a parked car reaches over 100°F within 20 minutes. On an 85°F sunny day, it can hit 120°F in the same time. Cracking windows makes almost no meaningful difference.
This isn’t just a summer problem, especially in Southern California. A spring afternoon with strong sunshine and no breeze can be just as deadly, especially considering spring travelers are often less vigilant because it “doesn’t feel that hot outside.”
The rule is simple: if the car is off and you are not in it, your pet is not in it. No exceptions for quick errands, gas station stops, or “just a few minutes.”
If you find a pet in a hot car in distress, including your own after a longer stop than planned, begin cooling immediately: shade, cool (not ice) water on the paws and groin, airflow, and get to the vet. Do not wait to see if they improve on their own.
Motion Sickness and Anxiety
Motion sickness is more common in pets than most owners realize, especially in dogs who don’t travel frequently. It’s caused by the same inner ear disruption that affects humans, and can produce drooling, yawning, whimpering, vomiting, and extreme lethargy in the car.
Anxiety compounds it. A dog or cat who is already stressed by travel, unfamiliar smells, confinement, and/or engine noise, will show more pronounced physical symptoms even without true inner ear disruption.
What helps:
- Travel on an empty or light stomach (no full meal within 3 hours of departure)
- Frequent short breaks for fresh air and a brief walk
- Keeping the car cool and well-ventilated
- Facing the pet forward in the vehicle where possible (rear-facing increases nausea)
- For significant cases, ask your vet about anti-nausea or anti-anxiety medications before your trip. They’re safe, effective, and make a real difference
When to be concerned: Vomiting once or twice is usually motion sickness. Repeated vomiting, bloody vomit, extreme lethargy, or signs of dehydration after vomiting are reasons to stop and seek care.
Injuries at Rest Stops and New Terrain
Rest stops and trailheads are exciting for dogs which means they’re also where leash lunging, sudden bolting, and rough terrain injuries happen. Sprained legs, cut paws, and injuries from jumping out of vehicles are among the most common travel-related issues we treat.
Unfamiliar terrain presents hazards that your dog doesn’t have the local knowledge to navigate. A trail they’ve never been on may have foxtails, sharp rocks, or unstable footing that their usual park doesn’t. Beach sand can hide glass, shells, and rocks that shred paw pads.
A few habits that reduce risk:
- Always attach the leash before opening the car door, not after
- Scout a new area briefly before letting a dog off-leash
- Check paws after any new terrain, especially beaches, desert, or heavily wooded areas
- Don’t let your dog jump from high vehicle cargo areas, instead lift them down or use a ramp
If your dog is limping, holding a paw up, or you notice a cut or swelling, follow the same guidance as any other orthopedic injury: minor and weight-bearing may be monitored; non-weight-bearing, swollen, or painful warrants same-day care.
Exposure to Unfamiliar Animals and Environments
Travel puts pets in contact with animals, insects, plants, and standing water they wouldn’t encounter at home. Each carries its own risk.
Wildlife encounters: Rattlesnakes are active in spring across Southern California and the Southwest. A snakebite to the face or leg is a true emergency as swelling, pain, and systemic effects begin quickly. Get to the nearest emergency vet immediately; anti-venom is time-sensitive.
Insect stings: Bee and wasp stings can cause localized swelling, but in pets with sensitivities, they can trigger anaphylaxis. Facial swelling, hives, vomiting, weakness, or collapse after time outdoors requires urgent care.
Standing water: Lakes, ponds, and puddles can carry leptospirosis, giardia, and blue-green algae (cyanobacteria), which can be rapidly fatal. If your dog swam in or drank from standing water and develops vomiting, diarrhea, lethargy, or neurological signs within 24 hours, seek care immediately and mention the water exposure.
Foxtails: As covered in a previous post, foxtails are everywhere in spring across California’s open spaces. Check ears, paws, eyes, and coat thoroughly after any time in dry grassy areas.
The Pet Travel Emergency Kit
You pack a first aid kit for your family. Your pet deserves one too. Before any road trip, put together a small kit that includes:
- Your pet’s vaccination and medical records (especially if crossing state lines)
- Your regular vet’s contact number and your nearest urgent care options at the destination
- A 1–2 week supply of any medications your pet takes regularly
- A collapsible water bowl and extra water
- A pet first aid kit: gauze, non-stick bandaging material, tweezers, saline wash
- A copy of your pet’s microchip number and a recent photo in case of separation
- Any comfort items such as a familiar blanket or toy reduces anxiety in new places
Most importantly: Know where you’re going before you need it. Before you leave, search for the nearest emergency or urgent care vet clinic at your destination and save the number in your phone.
