My dog has been having an allergic reaction for 7 hours now... when will the swelling go down? Does she need to be taken to a vet for a shot?

That definitely sounds concerning, and I completely understand why you're worried. Allergic reactions in dogs can vary in intensity and duration. The swelling you're noticing is likely caused by the body's release of histamines in response to an allergen. Common triggers include insect bites, certain foods, or even environmental factors like pollen.



In many cases, mild allergic reactions can subside on their own within a few hours to a day. You might try applying a cool compress to the swollen areas to help reduce the swelling and provide some comfort. Make sure she has access to plenty of water, as staying hydrated is important.



However, it's crucial to monitor for signs that could indicate a more serious reaction. If you observe difficulty breathing, extensive or worsening swelling, vomiting, diarrhea, or if she's acting very lethargic, these can be signs that she needs immediate veterinary attention. In cases of severe reactions, a vet may need to administer an antihistamine injection or other treatments to bring the symptoms under control.



To be safe, I recommend booking a video consult with one of our Dial A Vet professionals. They can help assess your dog's condition more thoroughly and advise you on the best next steps.
