Patient Spotlight: Copper! ⭐️🐾

This playful pup came to UrgentVet with diarrhea. Our team began testing for common causes, including parasites and Giardia. When Copper couldn’t provide enough of a sample to complete every test, we treated his symptoms, dewormed him as a precaution, and advised close monitoring.

Diarrhea can have many causes. If symptoms are severe or persistent, UrgentVet is here with expert urgent care and reassurance for you and your pet. Copper is on the mend! 💙🩺

Their athletic abilities are impressive, but even expert jumpers can have the occasional misstep.🐾

What’s the most impressive place your cat has managed to jump to? 👀

If your cat suddenly seems reluctant to jump, is limping, or isn’t moving like their usual self, it may be worth a closer look. Changes in mobility can sometimes signal an injury or other health concern.

If your cat needs care for an unexpected injury or illness, UrgentVet is here to help with urgent care when you need it. 💙

Did you guess it? The answer is… Rhodesian Ridgeback! 🐾

Fun Fact: Their signature “ridge” is a strip of hair along their back that grows in the opposite direction from the rest of their coat! Pretty paw-some, right? 🐶

At UrgentVet, we love celebrating every pup’s unique traits — big, small, and everything in between. ❤️

Sometimes the best part of the day is seeing the world through their eyes. 🐾

For Team Member Marie, one of those moments was spending a little extra time with Clover. Taking a moment to slow down, connect, and build trust can make all the difference, especially when a vet visit feels unfamiliar.

At UrgentVet, we believe caring for pets is about more than treating an illness or injury. It’s about helping them feel safe, comfortable, and cared for every step of the way. ❤️

Mesmerizing eyes aren’t just cute—they’re incredible tools! 🐱

A cat’s eyes are specially designed to help them see in low light, judge distance, and track movement, making them skilled little hunters. Their unique vision is just one of the many things that makes cats so fascinating. ❤️

At UrgentVet, we love helping pet parents learn more about the pets they love and keeping their furry family members feeling their best.

Fall is here, and your pet may have A LOT planned. ✔️

Some things are essential… like chasing squirrels, rolling in leaves, and claiming the coziest spot on the couch. Others? We’ll try to keep them off the list. 🐾

But if your pet’s fall plans do take an unplanned turn, UrgentVet is here. ❤️

After a walk, Goofy came in covered in tiny baby seed ticks! 😳🌿 These little pests can be easy to miss, especially after outdoor adventures.

Swipe to see Rio put his skills to the test. ➡️

During Rio's trip to UrgentVet, our team discovered that Rio has a special talent. And no, it’s not sitting pretty… it’s catching treats like a pro! 🍪

We’d say he’s got this trick in the bag, but he keeps eating the evidence. 👀

Not every outdoor adventure goes according to plan—just ask Maggie! 🐝

Maggie came to UrgentVet with facial swelling from a suspected insect sting, and our team was ready to help. Allergic reactions in pets can happen quickly and may cause swelling, redness, hives, and in some cases, difficulty breathing.

The good news? Maggie is feeling much better! Her swelling has gone down, and she's back to her happy, playful self—just the way we like to see our patients. 💙

When your pet's timing is a little... ruff, UrgentVet is here to help them get back to feeling their best.
