Emergency and after-hours vet care
If your pet is hurt, struggling to breathe, cannot urinate, has eaten something toxic, or is acting wrong in a way that scares you, do not wait for a regular appointment. These San Antonio hospitals take emergencies around the clock. In a real emergency, head in and call on the way, so the team can be ready for you.
BluePearl Pet Hospital, Stone Oak
Open 24/7 for emergencies. A specialty and emergency hospital in Stone Oak. Call ahead when you can, so they can talk you through your pet's situation and prepare for your arrival.
503 E Sonterra Blvd, Ste 102, San Antonio, TX 78258
(210) 930-8383
MissionVet Specialty & Emergency
Open 24/7 for emergencies, holidays included. A 24-hour emergency and specialty animal hospital on the northwest side, at Loop 1604 and Hausman Rd.
8202 N Loop 1604 W, San Antonio, TX 78249
(210) 737-7373
Thrive Pet Healthcare Specialists San Antonio
Emergency care open 24 hours, every day. San Antonio's longtime emergency pet hospital, now part of Thrive. Use the front entrance on Ceegee St for check-in.
2426 Ceegee St, San Antonio, TX 78217
(210) 822-2873
VEG ER for Pets
Open 24/7. An emergency and urgent care hospital at Park North on Loop 410, about ten minutes west of the airport. You can call ahead and speak with an ER veterinarian.
602 Northwest Loop 410, San Antonio, TX 78216
(210) 905-4640
Not sure whether it is an emergency? Call the hospital and describe what you are seeing; they will tell you whether to come in. If your own vet has an after-hours number, that message usually names the emergency hospital they refer to.
Poison help
If your pet may have eaten something toxic, minutes matter. Do not wait for symptoms. Call one of these two 24/7 poison lines right away, and keep the product or plant with you: the experts will ask what it was, how much your pet got, and your pet's weight.
ASPCA Animal Poison Control
The ASPCA's poison experts, available 24 hours a day, 365 days a year, for any animal poison emergency. A consultation fee may apply.
Pet Poison Helpline
A 24/7 animal poison control service for pet owners and veterinary professionals. The fee is $99 per incident, and follow-up consultations are included.
If your pet is lost
Act fast, and start with San Antonio Animal Care Services (ACS), the city shelter. Lost pets picked up inside the city are taken there, and the steps below follow ACS's own guidance.
1. Search the ACS listings right away, and keep checking. New animals arrive all day. Search for your pet on the ACS website.
2. Go in person, and walk the kennels every other day. ACS recommends the walk-through, because a pet can be missed in the listings, and a pet cannot be held for you by phone. ACS is at 4710 State Highway 151, San Antonio, TX 78227. Customer service: 3-1-1 inside the city, or (210) 207-6000.
3. Use the chip. If your pet is microchipped or licensed, ACS will try to contact you, so make sure the phone number on the chip is current. Call your microchip company and report your pet lost.
4. Post, and ask the neighborhood. Add your pet to Petco Love Lost, the free photo-matching database ACS points to, and ask Lost Dogs of Texas on Facebook to make a free lost-pet flyer. Ask neighbors and your mail carrier, put up flyers following the city's sign rules, and check the other shelters in the area.
Pet food help
A hard month should not mean an empty bowl, and it should never have to mean giving up a pet. These two organizations keep San Antonio pets fed.
DaisyCares Pet Food Bank
DaisyCares provides dog and cat food to San Antonio families going through a hard stretch, so pets stay fed and stay in the homes where they are loved. Their Hope & Health Grants also help qualified pet owners with urgent veterinary care costs.
San Antonio Food Bank
DaisyCares distributes pet food together with the San Antonio Food Bank. The Food Bank's Client Services team can tell you where to find food help near you, including pet food: call (210) 431-8326, Monday to Friday 8 AM to 6 PM and Saturday 9 AM to 3 PM.
5200 Historic Old Hwy 90, San Antonio, TX 78227
