After-hours and emergency vets: Boise and the Treasure Valley, ID
Last checked (America/New_York).
Call before you drive. The Treasure Valley has four hospitals that post 24/7 emergency hours: two WestVet hospitals (Garden City and Meridian), All Valley Animal Care Center in Meridian, and Viking Veterinary Hospital in Nampa. They are in three different cities, and public comments describe very different waits on different nights. The WestVet urgent-care clinic on South Meridian Road that older maps and directories still show appears to have closed (see below). If you can safely call, confirm the hospital is open, sees your pet’s species, and can take a new case now.
Hours can change with little public notice. Every hours line below is what the clinic’s public site posted on the date cited, not a live status.
This is not veterinary medical advice. This page is a local NightVet directory snapshot. It is not a complete list of every clinic in the metro, and it is not real-time monitoring. For medical guidance, call a veterinarian or a poison hotline. If a pet may have been poisoned, ASPCA Animal Poison Control is at (888) 426-4435; a consultation fee may apply (source seen November 12, 2026).
WestVet Urgent Care opened at 3030 S. Meridian Rd., Ste. 110, Meridian, on March 28, 2022, with posted hours of 10 a.m.–8 p.m. every day of the year (MedVet press release, March 28, 2022). On November 12, 2026, MedVet’s own URL for that location redirected to a page that returned “404 Not Found,” and a public post on the WestVet Urgent Care Facebook page is titled “WestVet Urgent Care services have moved to WestVet Boise” (Facebook post; NightVet could not load the post itself to confirm its date). Third-party directories such as VetsOpenNow still listed the Meridian address with 10 a.m.–8 p.m. hours as of their July 27, 2026 compile date (VetsOpenNow, seen Nov 12, 2026). Treat the South Meridian Road urgent care as likely closed and call WestVet before going there.
What local public threads have been asking
In a May 19, 2024 r/Boise thread asking whether WestVet was the only walk-in option on a Sunday, commenters pointed to All Valley’s 24-hour center in Meridian, Viking Vet in Nampa, and the WestVet urgent care in Meridian. One commenter said WestVet “does free triage over the phone.” Another, on May 22, 2024, counted four ER locations in the area (WestVet Garden City, All Valley Meridian, the then-new WestVet ER in Meridian, and Viking in Nampa) and said the Meridian urgent care had been filling up quickly for weekend walk-ins. Source: r/Boise, “Is West Vet the only real option…,” May 19–22, 2024.
In a February 13, 2025 r/Boise thread on 24/7 ER care, one commenter said they drive to the Meridian clinic because the Garden City hospital near them “has a 4-5 hour wait time.” Others described a roughly $5,000 bill at WestVet for an exam, X-rays, and orthopedic surgery, and a roughly $13,000 bill for a week-and-a-half hospital stay at All Valley, while praising staff at both. Source: r/Boise, “*HELP* Boise 24/7 ER Veterinary Care,” February 13, 2025.
A September 14, 2023 r/Boise thread had several commenters prefer All Valley over WestVet, one citing long waits at WestVet and another describing All Valley taking pets back for triage within 10–15 minutes. Source: r/Boise, “Emergency vets…,” September 14, 2023.
Those are individual public comments, not official fees or wait-time guarantees. A public X search on November 12, 2026 found no posts from the last 18 months that documented a closure or hours change at any of the four 24/7 hospitals below. One September 29, 2026 X post described a $650 visit to an unnamed “emergency vet in Boise” (X, @Thorny316, Sep 29, 2026); it does not name a clinic and is not used for any listing.
Clinics
1. WestVet Boise 24/7 Animal Emergency & Specialty Center — Garden City
24/7 emergency and multi-specialty hospital (MedVet network, operating as WestVet in Idaho). No appointment needed for emergencies. Does not do wellness care such as vaccines or spay/neuter.
Address / area
5024 W. Chinden Blvd., Garden City, ID 83714 (between Boise and Garden City on Chinden)
“ER Open 24/7”; the location page says the team is available 24 hours a day, 365 days a year.
Exam fees / deposits
No dollar exam fee is posted. MedVet’s network FAQ says an initial payment is required before a procedure, payment is due in full, and an exam is required even if your family vet already examined the pet. CareCredit is listed as a financing option.
Species
The page says to bring “your dog or cat.” Other species are not listed; call first for birds, reptiles, or small mammals. MedVet says its hospitals do not treat injured wildlife.
The most-named Boise ER in r/Boise threads from 2023–2025. Comments praise care and specialists but repeatedly mention long waits (one February 2025 comment said 4–5 hours) and high bills. A Facebook post says WestVet’s urgent-care services moved here from Meridian (see the closure note above).
2. WestVet Meridian 24/7 Animal Emergency & Specialty Center
24/7 emergency hospital with specialty services (internal medicine at opening). No appointment needed for emergencies. Opened in 2023.
Newer and less discussed in public threads than the Garden City hospital. No closure or hours-change notice found.
3. All Valley Animal Care Center — Meridian
24/7 emergency hospital (Thrive Pet Healthcare network) with emergency critical care, surgery, and orthopedics.
Address / area
2326 E. Cinema Drive, Meridian, ID 83642 The address is from a local vet practice’s after-hours referral list; the official page shows a map pin and phone but the address text did not load in our check.
The official page speaks of “your dog or cat.” Some third-party directories list exotics or horses; NightVet did not find that on the official page, so call first for other species.
Often recommended in r/Boise threads (2023–2025) as an alternative when WestVet Garden City has a long wait, with comments praising quick triage. One February 2025 comment described a roughly $13,000 bill for an extended stay. The old allvalleyanimal.com address now redirects to a Thrive page that returned 404 on Nov 12, 2026; use the Thrive location page above.
4. Viking Veterinary Hospital — Nampa
24/7 emergency and critical-care hospital that is also a general practice. Says it offers specialized care for exotic pets and has an in-house blood bank. States it is VECCS-certified as a Critical Emergency Center.
Address / area
16210 N. High Desert St., Nampa, ID 83687 (across from the Idaho Center, per a 2024 Reddit comment)
“Open 24 hours a day, 365 days a year.” General-practice appointments: Monday–Friday, 8 a.m.–5 p.m.
Exam fees / deposits
No dollar fee posted. The FAQ says emergency visits start with a doctor exam, after which staff show estimates for diagnostics or hospitalization. Payment options listed: cash, credit cards, CareCredit, Scratch Pay, and Trupanion insurance.
Species
Pets generally; the About page says the hospital offers “specialized care for exotic pets.” Which exotic species are seen overnight is not specified; call first.
Named in r/Boise threads from 2023 and 2024 as the Nampa 24/7 option and as open on Sundays. No closure or hours-change notice found.
Daytime clinics that send people elsewhere after hours
Some Boise general practices take same-day urgent cases during business hours but post that they are closed nights and weekends and refer after-hours emergencies to WestVet Boise. Examples: Broadway Veterinary Hospital (posted Monday–Friday, 8 a.m.–5 p.m.; site, seen Nov 12, 2026) and Hidden Springs Animal Hospital (posted Monday–Friday, 8:30 a.m.–5:30 p.m.; site, seen Nov 12, 2026). A September 2023 Reddit commenter noted that Broadway’s “8 days a week” sign can make it look like an ER when it is not open around the clock.
