Rattlesnakes and Dogs in Scottsdale: Which Clinics Hold Anti-Venom

The nearest clinic and the right clinic can be different places. Scottsdale's own trailhead clinic list with the anti-venom flags, and the season that lands exactly on top of dog hiking weather.

Scottsdale does something for dog owners that no other city in this guide series does. It publishes a list of the veterinary clinics nearest each Preserve trailhead, and it states which ones hold rattlesnake anti-venom on site.

Two of the five day clinics on that list say they hold none.

Which means the nearest clinic and the right clinic can be different places, and the fifteen minutes you spend reading this now is the fifteen minutes you will not have later.

The season, and why it collides with dog season

From the city's rattlesnake page, verbatim:

"When temperatures are between 60°F and 90°F, the cold-blooded reptiles of the Preserve will emerge from hibernation; this includes rattlesnakes. Rattlesnakes are an important part of the Preserve ecosystem and are a protected species."

Sixty to 90 degrees. Now set that against the Preserve's dog rule, verbatim from the Preserve page, where the sentence is split across two lines: over "90 degrees at any time in your hike, it's too hot for your dog."

Below 90 is when you can bring the dog. Sixty to 90 is when the snakes are out. The two windows are the same window. There is no month in Scottsdale that avoids both problems, and pretending otherwise is how people get caught out in March.

The clinic list, grouped as the city groups it

Read from the city's nearest-veterinarian-clinics PDF, which is titled "Nearest Veterinarian Clinics to Scottsdale's McDowell Sonoran Preserve Trailheads".

Nearest to Pima Dynamite, Brown's Ranch, Tom's Thumb, Granite Mountain and Fraesfield Trailheads

Clinic	Phone	Address	Hours as published	Anti-venom
Dynamite Animal Hospital	480-538-0900	10031 E. Dynamite Blvd., Ste. 100	M-F 8:30 a.m. to 5:30 p.m.	"Anti-venom on site for rattlesnake bites."
Pima North Animal Hospital	480-563-5432	8864 E. Pinnacle Peak Road, Ste. K-1	M-F 7 a.m. to 6 p.m., Sat 7 a.m. to 1 p.m.	"Anti-venom on site for rattlesnake bites."

Nearest to Gateway and Bell Road Trailheads

Clinic	Phone	Address	Hours as published	Anti-venom
McDowell Mountain Animal Hospital	480-419-6300	17050 N. Thompson Peak Pkwy., Ste #B 100	M-F 8 a.m. to 6 p.m., Sat 8 a.m. to 5 p.m.	"NO anti-venom"

Nearest to Lost Dog Wash and Sunrise Trailheads

Clinic	Phone	Address	Hours as published	Anti-venom
Animal Clinic Del Rancho	480-405-5485	11445 E. Via Linda, Ste #10	M-F 7:30 a.m. to 5:30 p.m., Sat 8 a.m. to 12 p.m.	"Anti-venom on site for rattlesnake bites"

Read the gap. The two trailhead groups closest to central Scottsdale, Gateway and Lost Dog Wash, are the ones whose nearest clinic holds no anti-venom. Del Rancho covers Lost Dog Wash. Gateway's only listed clinic does not.

And read the hours. Every clinic in that list closes on weekday evenings, and three of the five are shut on Saturdays or shut early. A Sunday bite goes to an emergency hospital, not to any of these.

The four emergency clinics, all flagged as holding anti-venom

Page two of the same PDF, headed emergency clinics. All four carry the note "Anti-venom on site for rattlesnake bites".

Clinic as the city names it	Phone as the city gives it	Address
Emergency Animal Clinic	480-949-8001	22595 N. Scottsdale Road, Ste #110
VCA Paradise Valley Animal Hospital	602-551-8341	10380 N. Hayden Road
Animal Medical and Surgical Center	480-462-5921	17477 N. 82nd St.
VetMed	602-697-4694	20610 N. Cave Creek Road

Three of those four names are out of date. At the same addresses, Maricopa County's 24-hour directory lists BluePearl Scottsdale, VCA McCormick Ranch Animal Hospital and Emergency Center, and Thrive Pet Healthcare Specialist North Scottsdale, and gives a different phone number for two of them.

So use the addresses from the city's list and the phone numbers from the county's. Our emergency vets in Scottsdale guide sets the two lists side by side, including the one hospital whose own page we could read to settle the conflict.

The city attaches a disclaimer to all of it, verbatim: "These clinics are not endorsed by Scottsdale; this is provided as an informational reference." And on how it chose them, verbatim: "The criteria for this list consists of the nearest veterinarian clinics to Scottsdale's McDowell Sonoran Preserve Trailheads."

It is a proximity list, not a quality ranking. The anti-venom flags are the part that carries real information.

How to avoid the bite in the first place

The city's avoidance list, verbatim:

"Always stay ALERT and AWARE of your surroundings" "Travel only on designated and posted trails" "DO NOT TRAVEL OFF TRAIL" "Do not place your hands or feet in places you cannot see" "Always keep your dog(s) on a leash"

The capitals are the city's.

"Always keep your dog(s) on a leash" is on the snake list, not just the general rules list, and the Preserve rule is stricter than a lead: it requires a handheld leash no longer than six feet at all times. A dog casting six feet into the brush at the side of the trail is doing the one thing that gets a nose bitten.

The trail-only rule matters for the same reason. Verbatim: "DO NOT go off trail to avoid the rattlesnake; there might be another one in the brush."

If you meet one on the trail

Verbatim from the city:

"PAUSE and quickly locate the snake" "Move slowly and deliberately to a safe distance" "Rattlesnakes will not chase you" "DO NOT go off trail to avoid the rattlesnake; there might be another one in the brush" "Provide a caution to other users in the area about the snake's presence" "Most importantly - LEAVE IT ALONE"

"Rattlesnakes will not chase you." Useful to know while you are shortening the lead and backing up the trail.

With a dog, the whole encounter turns on the lead. Six feet in your hand means you can lift and turn. A dog on a long line or off the lead has already made the decision for you.

If your dog is bitten

Be clear about one thing before you read further. The city's own first aid steps on that page are written for people. Verbatim: "Remove jewelry and tight-fitting clothing in case of swelling" and "Immobilize the extremity and keep it below the heart" and "Call 911 and get medical help as soon as possible".

Jewelry and 911 tell you the audience. Do not apply that list to a dog, and do not call 911 for a dog.

One line on the page does generalise, verbatim:

"If bit by a rattlesnake in the state of Arizona, do not catch, try to identify or kill it . This can risk in a second bite and will waste time that needs to be focused on getting medical attention. Medical professionals treat all rattlesnake bites with the same antivenom, regardless of species."

The stray space and the grammar are the page's. The point stands and it is the useful one: you do not need to identify the snake. Nobody at the clinic needs a photograph. Leave it and go.

For the dog, what the city gives you is the clinic list above. The sequence that follows from it:

Carry the dog if you can. Movement moves venom, and a bitten dog that walks two miles out is doing itself no favours. This is also the argument for turning back early on long routes.

Ring the clinic while you are moving. Ask two questions: are you open, and do you have anti-venom. The city's flags tell you where to start; they do not tell you what is in the fridge today.

Go to a clinic that says it holds it. If the nearest one does not, the extra ten minutes to one that does is usually the better call, and the clinic on the phone will tell you.

And know the hours. Every day clinic on the city's list is closed evenings and most of the weekend. Our emergency vet, what to know guide covers what happens when you arrive, and our pet first aid basics guide covers the general principles.

We are not printing canine first aid steps for a snake bite, because no source we could verify publishes them for Scottsdale. The verified instruction is: get to a clinic that has anti-venom, and let them tell you what to do on the way.

What to have in the car all season

The clinic list, printed or screenshotted. Not a bookmark, because signal in the Preserve is unreliable and you may be reading it in a car park.

Both a nearest clinic and a nearest anti-venom clinic, because in two of the three trailhead groups they are not the same place.

Water for two, which the Preserve requires in effect through its half-gone turnaround rule, verbatim: "Bring ample water for you and your dog. When it is half gone, turn around."

A way to carry the dog. A harness with a handle, or a plan.

And the licence tag on the collar. Different problem, same principle: our Maricopa County dog licence guide covers why it changes what happens if your dog bolts, and our lost dog in Scottsdale guide covers the timeline if it does.

Where snakes and dogs meet outside the Preserve

The Preserve is not the only place. Pinnacle Peak Park's page warns, verbatim: "Rattlesnake activity varies seasonally. Stay on the trail at all times and stay alert." That park bans dogs from its trail entirely, which our Pinnacle Peak Park and dogs guide covers.

For snakes in a residential area, the city routes you elsewhere, verbatim: "For information about when a snake is in a residential area , go to Fire | Safety Awareness". We have not read that page, so we are not summarising what it says.

And the four dog parks are fenced grass rather than desert, which is one more reason they are the sensible default in the months when the Preserve is difficult. Our Scottsdale dog parks guide covers all four, and our dogs in the McDowell Sonoran Preserve guide covers the trail rules in full.

Frequently asked questions

Which Scottsdale vet clinics have rattlesnake anti-venom? The city flags Dynamite Animal Hospital, Pima North Animal Hospital and Animal Clinic Del Rancho as holding anti-venom on site, and states "NO anti-venom" for McDowell Mountain Animal Hospital and KC Animal Hospital. All four clinics on its emergency page are flagged as holding it.

When are rattlesnakes active in Scottsdale? The city states that the cold-blooded reptiles of the Preserve emerge from hibernation when temperatures are between 60 and 90 degrees Fahrenheit, and that this includes rattlesnakes.

Does the snake season overlap with dog hiking season? Yes, almost exactly. The Preserve tells dog owners that over 90 degrees at any point in the hike is too hot for the dog, so the temperatures cool enough for a dog are the same temperatures that bring the snakes out.

What should I do if my dog is bitten by a rattlesnake? Get to a clinic that holds anti-venom, ringing ahead to confirm it is open and has it. The city's own first aid steps on its rattlesnake page are written for people, not dogs, so do not apply them to a dog.

Should I try to identify the snake? No. The city states that you should not catch, try to identify or kill it, that doing so risks a second bite and wastes time, and that medical professionals treat all rattlesnake bites with the same antivenom regardless of species.

Do I call 911 if my dog is bitten? No. The 911 instruction on the city's page is part of first aid guidance written for people. For a dog, ring a veterinary clinic that holds anti-venom.
