Allergic Reaction in a Dog: How Can A Routine Walk Turn Into An Emergency: Juno’s Story
Did you know that dog allergic reactions can become life-threatening?
In fact, allergic reactions are one of the common causes of emergency vet visits. The cause is often not discovered—anything can be an antigen for your dog.

Juno’s story
You take your dog for a lovely evening walk and suddenly you notice some bumps around the muzzle. The bumps turn into goose eggs until your dog’s face swells up to twice its normal size right in front of your eyes.
What happened? A sting? A bug bite?
The symptoms
Your dog is overheating, panting and breathing heavily. The tongue is swelling. The race against the clock begins.
Who takes Benadryl out on their walks?
I admit I don’t either. But maybe now I will. I do have our vet’s and all emergency numbers programmed in my phone, though. And fortunately, our provider has pretty good coverage pretty much everywhere.
Juno’s parents did not have the numbers handy and the phone did not work where they were.
Race against the clock
Their only option was to make it back home.
Juno was frantically running around, scratching her face, rubbing her head and body on the ground and against everything and anything in sight. Her eyes were barely visible with all the swelling and her tongue was enormous.
At the veterinarian
Finally, they made it to the vet.
A dose of epinephrine started to get the swelling down.
Once Juno could be properly examined, there was no entry wound or puncture marks to be found. She must definitely got bitten or stung but the evidence of what it could have been was not there.
By next morning Juno’s face was still swollen but nowhere near as bad and her tongue went back to normal size.
Take home message
Needless to say that Juno’s parents now always have Benadryl tablets on hand for every walk or trip they take.
Everything ended well for Juno.
But her story comes to show that one should never venture anywhere unprepared. Some allergic reactions can be deadly.
