About Lodestar

Here for Your Pet, Any Hour of Any Day

A pet emergency is one of the most frightening things an owner can face — and it almost never happens at a convenient time. A dog gets into something toxic late at night. A cat suddenly can't breathe on a holiday weekend. An old friend takes a turn for the worse when every regular clinic is closed. In those moments, you need somewhere that's genuinely open, fully equipped, and ready to help right now. That's why Lodestar exists.

We're a 24/7 emergency and full-service animal hospital, open 24 hours a day, 365 days a year — not just on paper, but truly staffed and ready at every hour. For seventeen years, we've been the place Houston pet owners turn to when the unexpected happens. Unlike a regular clinic that closes at night, and unlike a bare-bones emergency room, we're a complete hospital: our team includes emergency doctors and surgeons; we have an on-site intensive care unit for critical patients, a fully equipped surgical suite, digital imaging, and an in-house laboratory that delivers results in minutes, not days. That means when your pet arrives in crisis, everything needed to diagnose, stabilize, and treat them is right here, around the clock. And because we're a full-service hospital, we also provide everyday wellness and urgent walk-in care, so we can be your one trusted place for both the routine and the unexpected. Through every emergency, we combine genuine medical capability with real compassion — we know how terrifying these moments are, and we treat both your pet and you with expertise, honesty, and heart. We also coordinate closely with your regular veterinarian, keeping them informed and returning your pet to their care with a clear plan. When something goes wrong at 2 a.m., on a holiday, or in the middle of a workday, you shouldn't have to wonder where to go. You come to Lodestar, and you're never alone. We're always open, always ready, and always here for your pet.

From Houston Pet Owners

Trusted When It Matters Most

I will be forever grateful to Lodestar. My dog started vomiting and collapsed at 3 in the morning, and they were the only place open and ready to help. We rushed in and their team took over immediately — calm, fast, and incredibly skilled. They quickly diagnosed a serious problem, got him stabilized, and their critical-care team monitored him around the clock. The fact that a fully equipped hospital with emergency surgeons and an ICU was open in the middle of the night saved my dog's life, plain and simple. Throughout the terrifying ordeal, they kept me informed, explained everything clearly, and treated both my dog and me with genuine compassion. When you're facing the worst at 3 a.m., having a place like Lodestar — always open, always ready, and truly expert — is everything. He made a full recovery and is back to his happy self. I can't recommend them highly enough. If your pet ever has an emergency in Houston, this is where you want to be. They are lifesavers in every sense.
Alicia G.Emergency patient's owner, Bellaire
Our cat swallowed something she shouldn't have on a Sunday, when our regular vet was closed, and Lodestar was there for us. We walked in without an appointment and were seen quickly. They ran diagnostics, determined she needed emergency surgery, and their surgical team operated that same day. The whole time, they were transparent about what was happening and what it would involve, and they clearly prioritized doing right by our cat. Their critical-care monitoring afterward was excellent, and she recovered beautifully. What struck us was how seamlessly they combined true emergency capability — surgeons, imaging, an ICU, a lab, all in-house and available on a weekend — with real warmth and care. Knowing there's a place in Houston that's genuinely open and fully equipped 24/7, not just on paper, gives us enormous peace of mind as pet owners. They also coordinated follow-up with our regular vet. We're so thankful they were open and ready when we needed them. Lodestar is the real deal for emergency and urgent pet care.
The Nguyen familyEmergency surgery, West University
We've brought our pets to Lodestar for both emergencies and routine care, and they excel at both. What we love is that it's a true full-service hospital that also happens to be open 24/7, so it's become our one place for everything. For wellness visits, their vets are thorough, knowledgeable, and never rushed. And on the two occasions we've had a real emergency — once late at night and once on a holiday — they were open, ready, and outstanding, with the diagnostics, surgery, and critical-care capabilities to handle serious situations that a regular clinic simply can't. Having that level of care available at any hour, from a team that also knows our pets from their regular visits, is incredibly reassuring. The staff genuinely care, the facility is impressive, and they communicate clearly every step of the way. For any pet owner in Houston, having Lodestar as your hospital means you're covered no matter what happens or when. We trust them completely with our animals, in a crisis and in everyday life. They've earned our loyalty many times over.
Marcus D.Emergency & wellness client, The Heights
When our senior dog took a sudden turn for the worse late one evening, we panicked, but Lodestar was open and calm and exactly what we needed. From the moment we arrived, their emergency team moved quickly and expertly, running diagnostics to figure out what was wrong and getting him comfortable and stable. He needed to stay in their ICU for several days, and their critical-care team was phenomenal — attentive, skilled, and endlessly kind, updating us constantly and letting us visit. Being able to access round-the-clock intensive care, advanced imaging, and specialists all in one hospital made a genuine difference in his outcome, and he pulled through. Just as important, the team supported us emotionally through a frightening, exhausting time with real compassion and honesty. They never made us feel rushed or like just another case. Houston is lucky to have a hospital like this that's truly open and fully staffed 24/7. If your pet ever faces an emergency or critical illness, Lodestar has the capability and the heart to help. We are deeply grateful to everyone there.

Emergency & Hospital FAQ

Are you really open 24 hours, every day?

Yes — we are genuinely open 24 hours a day, 365 days a year, including nights, weekends, and every holiday, and we're fully staffed and equipped the entire time. This is an important distinction, because some places advertise emergency availability but are actually limited overnight or on holidays, or are on-call only. At Lodestar, our doors are open and our team — including emergency doctors, technicians, and critical-care staff — is here and ready around the clock, every single day of the year. Whenever your pet has an emergency or urgent problem, no matter the hour, you can come straight in or call us. There's never a time when we're closed or unavailable. We built our hospital this way because pet emergencies overwhelmingly happen outside of normal business hours — late at night, in the early morning, on weekends, and on holidays when regular clinics are shut — and that's exactly when families need somewhere to turn. Knowing there's a fully operational veterinary hospital in Houston that never closes gives pet owners real peace of mind. So if you're ever wondering whether we're open, the answer is always yes. Day or night, weekday or holiday, we're here for you and your pet.

Do I need an appointment, or can I just come in?

For emergencies and urgent problems, you never need an appointment — just come straight in, any hour of any day, and our team will see your pet promptly, triaging the most critical cases first, exactly as a hospital should. If your pet is having an emergency, please don't wait to call ahead or book anything; time can matter enormously, so come in right away, though calling us on your way so we can prepare is helpful if it's convenient. Walk-ins are always welcome for urgent care. For non-emergency general and wellness care — routine exams, vaccines, and the like — appointments are helpful so we can plan your visit, and you can call or use our contact form to schedule. But the whole point of a 24/7 hospital is that you're never turned away and never left waiting for the next available opening when your pet urgently needs help. If something is wrong and you're not sure whether it's an emergency, you can always call us and we'll help you decide whether to come in immediately; when in doubt, it's safer to come in. Our goal is to make getting your pet care as fast and stress-free as possible in a frightening situation. So for anything urgent, skip the appointment and come to us — we're ready.

How do I know if my pet's situation is an emergency?

This is one of the most important things for pet owners to understand, and when in doubt, it's always safer to call us or come in. Some signs are clear emergencies that require immediate care: difficulty breathing or blue or pale gums; collapse, extreme weakness, or unresponsiveness; suspected poisoning from foods, medications, plants, or chemicals; serious trauma such as being hit by a car, major wounds, or uncontrolled bleeding; a bloated, hard abdomen or repeated unproductive retching; seizures; repeated vomiting or diarrhea, especially with blood; inability to urinate or straining to urinate, which is especially dangerous in male cats; difficulty giving birth; and signs of severe pain or extreme distress. Other situations, like a worsening illness, a wound, limping, or your pet just not being themselves, may be urgent even if they're not immediately life-threatening, and we can help with those too. The truth is you don't have to diagnose the emergency yourself — that's our job. If your pet is showing any of the serious signs above, come in immediately. If you're unsure whether something warrants a visit, call us at (713) 555-0111 any time and describe what's happening; we'll help you decide and, if needed, prepare for your arrival. We would always rather you come in and have it turn out to be minor than wait on something serious. Trust your instincts — if you feel something is wrong, we're here.

What makes you different from a regular vet clinic or a standalone ER?

Lodestar combines the best of both worlds: we're a complete, full-service animal hospital, and we're open 24/7 with true emergency and critical-care capabilities. A typical general-practice vet clinic provides excellent everyday care but closes at night and on weekends and usually isn't equipped for major emergencies, surgery around the clock, or intensive care. A standalone emergency room handles crises but often only operates after hours, may lack the full range of hospital services, and isn't somewhere you'd go for routine care. We bring it all together under one roof, all the time. That means we have emergency doctors and surgeons, an on-site intensive care unit, a fully equipped surgical suite, digital imaging, and an in-house laboratory, staffed and available every hour of every day — so a pet arriving in crisis at 3 a.m. gets the same comprehensive hospital capabilities they'd get during the day. And because we're also a full-service hospital offering wellness and urgent walk-in care, we can be your single trusted place for both routine needs and emergencies, with a team that gets to know your pet. This integration matters in a crisis: everything needed to diagnose, stabilize, operate on, and intensively care for your pet is right here, immediately, without transferring between facilities. For Houston pet owners, it means complete, capable care is always available, whatever happens and whenever it happens.

Will you work with my regular veterinarian?

Absolutely — we see ourselves as a partner to your regular veterinarian, not a replacement, and coordinating with them is a standard part of how we care for your pet. Your family vet is central to your pet's ongoing health, and when we treat your pet for an emergency or urgent issue, we make sure that care connects smoothly back to them. We keep records of everything we do, communicate our findings and treatment to your regular veterinarian, and return your pet to their care with a clear summary and plan for any follow-up needed, so your vet stays fully informed and can continue managing your pet's health seamlessly. If your regular vet ever refers you to us for after-hours emergency care, advanced diagnostics, surgery, or critical care they can't provide, we handle that referral smoothly and keep them in the loop throughout. And because we also offer general and wellness care, some families choose to use us for everything, while others keep their beloved family vet for routine care and rely on us for emergencies and urgent needs — either way works, and we support it. The goal is that your pet's care is coordinated and complete, with everyone on the same page. You never have to worry that using us for an emergency will disrupt your relationship with your regular vet; we're here to complement it and to make sure your pet gets the right care at every hour.
