When Elmer the Beagle got his paws on some raw chocolate chip dough, things quickly took a turn! 🐶🍪

His pet parents brought him to UrgentVet Carytown, where the team acted quickly to help. With medication to induce vomiting, they discovered Elmer had eaten a whopping 2.4 pounds of dough! 🍞

Raw bread dough can be dangerous for pets because the yeast continues to ferment in their stomach, producing alcohol that can lead to toxicity. Add chocolate to the mix, and it's important to seek veterinary care right away.

Thankfully, Elmer got the care he needed!

When your pet runs into a bit of "Ruff Timing", UrgentVet is here to help. 🐾

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.

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. 💙
