Last July I stood in a rest area in South Dakota with a border collie mix named Dot bleeding onto my jeans, and the only things in the car were a roll of paper towels and a gallon jug of water. She had cut a front pad on broken glass in the grass. We were still hours from Decorah. I rinsed the paw, wrapped it in a dish towel, and drove. That drive is the reason a first aid kit now lives under my driver's seat, and the reason I wrote this list down.
In March 2025 our vet, Dr. Lindqvist, asked me a plain question: what do you carry in the car for the dogs? I did not have a good answer. I bought the ARCA PET first aid kit a week later, mostly because it came as a hard case with a small pouch inside and it fit under the seat without me rearranging anything. Three dogs ride in that Highlander, Biscuit, Dot, and Murphy, and the case has been back there with them ever since.
The case that answered Dr. Lindqvist's question
75 pieces in a water resistant nylon case about the size of a thick paperback, with a mini pouch that drops straight into a walking bag. Mine has ridden under the driver's seat since March 2025.

Dot's cut was shallow. Dr. Lindqvist confirmed that the next morning, no stitches, healing fine. But shallow cuts still bleed, and a dog standing in a rest area lot with a bleeding paw is not a dog you can walk back to the car easily. What I needed was gauze, a bandage, and something to rinse with. The case had the gauze and the bandage. I had the water. Five minutes, and she was up on the seat.
The right tick tool gets the mouthparts out in one go
Backbone State Park, June 2025, our tent weekend. I found a tick on Murphy's shoulder while I was brushing him off before bed. Tweezers work if you are careful and lucky. The tick removal tool in the case seats around the body of the tick and lifts it out, and I had it clean on the first try. I put it in a baggie and showed Dr. Lindqvist at the next visit. Nothing came of it. That is the outcome you want.
An emergency muzzle protects the person trying to help
I have never used the muzzle in my kit, and I want to be honest about that. But a dog in pain does not always behave like the dog you know, and Dot is the anxious one to begin with. The muzzle is in there so that if I ever have to look at a wound on a hurting dog at the side of a road, I am not the second casualty. If you have never put one on a dog, practice at home first, on a calm afternoon, with treats.
It fits under the driver's seat and it stays there
The ARCA PET case measures 8.5 by 6.5 by 3.25 inches and weighs about 1.55 pounds. Think of a thick paperback. Mine slides under the driver's seat of the Highlander and I do not move it, not for groceries, not for the beds, not for the water bottles. The nylon is water resistant with reflective printing, and it is a hard case, so it does not collapse when a 46 pound Lab steps on it.
The mini pouch goes where the case cannot
A kit under a seat does you no good two miles down a trail. There is a small pouch inside the main case, and that pouch lives in my walking bag now. It is the part I actually touch between trips. When we stop at a rest area and walk the dogs, the pouch comes with me and the big case stays in the car. Splitting the kit is the single most useful thing I did with it.
The handbook answers the questions I would have searched badly
There is a first aid handbook in the case. I read it at my kitchen table in March, in one sitting, because I wanted to know what I owned. Some of it is beyond what I would attempt myself, and that is the point. I am not a vet and I do not play one. What the handbook does is tell me what is worth a phone call and what is worth a drive into Decorah, and it does that faster than my phone at a rest stop with one bar of signal.
A flashlight in the case is a flashlight you can find
My glovebox flashlight is always dead or missing. The one in this ARCA PET case sits with the kit, and I check it works before every trip, which takes about nine seconds. If Dot's cut had happened at dusk instead of midday, I would have needed light to see how deep it went. Small thing. A kit is made out of small things, and the flashlight is the one I would have forgotten to pack on my own.
A spare leash turns one person into two
The kit includes a leash. There are already three leashes in the Highlander, one per dog, plus the seatbelt tethers. But leashes get left in motel rooms and in walking bags. Having a fourth one folded in the case means that when Gene comes along and we split up at a rest stop, nobody is holding two dogs on one strap. Gene comes on about half our trips. That is exactly when the extra leash earns its place.
Gauze and ointment handle most of what actually happens
Most of what goes wrong on a trip is small, and I hope it stays that way. Dot's pad was the only real injury we have had, and the gauze and bandage in the ARCA PET case handled the drive home. After the rinse I used the antibiotic ointment. I am not going to tell you how to treat a wound. I am not qualified, and my advice in any health situation is the same one: call your vet. What I will tell you is that having the supplies in one place meant I did not have to decide anything while I was upset.
It answers the question your vet is going to ask you
Dr. Lindqvist asked what I carried in the car. Back then I had nothing worth naming. Now I can tell her: an ARCA PET case under the seat with gauze, bandages, a tick tool, a muzzle, a leash, a flashlight, ointment, and a handbook. She nodded, which from her is a lot. You do not carry a kit because something dramatic is going to happen. You carry it so that when your vet asks, and she will ask, you are not describing paper towels.
What I'd Skip
A few things I would not bother with. I would not buy a soft sided bag for a car with three dogs in it, because my ARCA PET case is a hard case and it survives being stepped on. I would not buy a kit the size of a tackle box, because you will never move it from the garage to the car. I would not pay extra for a kit that is mostly a thermometer and a booklet. And I would skip anything advertised as a stand in for your vet, because it is not one. My one real complaint about this kit: I had to read the handbook at home to know what was in there, and a few of the contents are basic. I would buy it again. What I would change is buying it sooner. I waited until something happened, and I got lucky that the something was small.

Before the next trip, put one thing under the seat
A hard case, 75 pieces, water resistant nylon, about the size of a thick paperback, with a mini pouch for the walking bag. Mine has been under the driver's seat of a Highlander since March 2025, through three dogs and three states.
