Emergency Vet Care in San Jose

ARCH Veterinary functions as a true animal emergency hospital San Jose pet owners can reach without a referral or pre-scheduled appointment. Our Winchester location at 824 N Winchester Blvd is staffed with veterinarians, licensed technicians, and support team members trained for urgent and critical patients. We focus on rapid triage on arrival, stabilization first, then targeted diagnostics — X-ray, ultrasound, CT, and in-house laboratory testing — and treatment plans that match the severity of the case. We are not a 24-hour facility; we are a high-capability daytime and evening pet ER San Jose families can rely on, open every day until 10 PM, which covers the hours when most pet emergencies actually happen.

When Your Pet Should See an Emergency Vet

If you are searching for an emergency veterinarian San Jose at midday, after work, or on a weekend, trust your instincts. You should be seen the same day for: difficulty breathing or open-mouth breathing in cats, pale or blue gums, repeated vomiting or diarrhea, suspected toxin ingestion, an inability to urinate, a swollen or distended abdomen, a seizure, collapse, severe limping, deep wounds, eye injuries, heat stroke, allergic reactions with facial swelling, or any sudden change in behavior in a young, senior, or chronically ill pet. When in doubt, call our hospital — our team can help you decide whether your dog emergency or cat emergency needs an immediate walk-in or whether it can be safely managed at home until morning.

Common Pet Emergencies We Treat

Our emergency caseload spans the full range of pet emergency San Jose presentations: gastrointestinal foreign bodies, pancreatitis, parvovirus, hemorrhagic gastroenteritis, urinary obstructions, pyometra, diabetic crises, fractures, lacerations, dog fight wounds, snake and spider exposures, heat stroke, asthma flares, congestive heart failure, glaucoma, and post-operative complications from procedures performed elsewhere. We also see exotic emergencies in rabbits, reptiles, birds, and pocket pets when our exotics doctor is on. Every case begins with a hands-on triage exam and a clear conversation about what we recommend, what it is likely to cost, and what the realistic outcomes look like.

Vomiting, Diarrhea, and Not Eating

Repeated vomiting, bloody or black stool, refusal to eat for more than a day, or vomiting paired with lethargy and abdominal pain can signal an obstruction, pancreatitis, kidney disease, addisonian crisis, or toxin exposure. Puppies, kittens, and small breeds dehydrate quickly. Cats that stop eating for even 48 hours risk hepatic lipidosis. Same-visit care typically includes a focused exam, hydration assessment, bloodwork, parvo or pancreatitis testing, abdominal imaging, anti-nausea medication, IV fluids, and a decision tree about hospitalization, medical management, or surgery.

Toxin Ingestion and Poisoning

Chocolate, xylitol (sugar-free gum and peanut butter), grapes and raisins, onions, lilies (deadly to cats), rat and mouse poison, marijuana, ibuprofen, acetaminophen, ADHD stimulants, and antidepressants are among the toxins we see most often. Bring the packaging, the time of ingestion, and your pet's weight if known. Do not induce vomiting at home unless a veterinarian or poison control directs you to. We can perform safe decontamination, administer activated charcoal or specific antidotes, monitor liver and kidney values, run clotting tests for anticoagulant rodenticides, and hospitalize for IV support when needed.

Urinary Blockage in Cats and Dogs

A male cat straining in the litter box, vocalizing, vomiting, or hiding may have a life-threatening urinary obstruction. Within 24 to 48 hours, a blocked cat can develop dangerous potassium elevations and cardiac instability. Dogs can also obstruct from bladder stones or tumors. Treatment includes pain control, sedation, urinary catheterization, IV fluids, electrolyte correction, bloodwork, urinalysis, imaging, and 24 to 72 hours of hospitalization with monitoring. Long-term management includes diet, environmental enrichment, and follow-up imaging — coordinated with our /vet-hospital-san-jose primary care team.

Trouble Breathing, Seizures, or Collapse

Open-mouth breathing in a cat is always an emergency. A dog breathing heavily at rest, coughing up foam, or with blue-tinged gums may have heart failure, pneumonia, airway obstruction, or fluid around the lungs. Seizures lasting longer than three minutes, cluster seizures, or first-time seizures in any pet should be evaluated immediately. Collapse can stem from cardiac disease, internal bleeding from a splenic mass, low blood sugar, or addisonian crisis. We start oxygen, IV access, and emergency medication before extensive testing — stabilization always comes first.

Trauma, Bite Wounds, Limping, and Pain

Hit-by-car cases, dog fights, falls from height, and being stepped on can produce hidden injuries that look minor on the surface — bruised lungs, ruptured bladders, internal bleeding, or pelvic fractures. Even a calm, walking pet after trauma needs a thorough exam. Bite wounds create deep pockets of tissue damage that need debridement, drains, antibiotics, and pain control. Sudden severe limping may indicate a fracture, ligament tear, or immune-mediated joint disease. We provide multimodal pain management before any procedure that may cause discomfort.

Emergency Diagnostics: X-Ray, Ultrasound, Lab Work, and CT

Fast, accurate diagnostics change emergency outcomes. Our hospital offers in-house digital X-ray, abdominal and thoracic ultrasound, comprehensive bloodwork and urinalysis, blood gas and electrolyte analysis, coagulation testing, and same-day veterinary CT imaging — see /ct-scan-san-jose for details. CT is invaluable for trauma, nasal disease, complex foreign bodies, cancer staging, and surgical planning. Having advanced imaging on site means we do not lose hours transferring patients during a crisis. Results are interpreted by our doctors and, when appropriate, reviewed by board-certified radiologists.

Emergency Surgery and Hospitalization

Some emergencies require the operating room the same day. We perform emergency soft-tissue procedures including foreign body removal, splenectomy for bleeding masses, gastric decompression and gastropexy for bloat, cesarean sections, wound repair, abscess management, and exploratory laparotomy. Pets that need overnight observation are hospitalized in our treatment ward with continuous monitoring during operating hours; cases requiring true overnight critical care are stabilized and transferred to a 24-hour facility with full medical records.
