My dog got stung by a bee, has hives. When should I call the vet?

This is probably an allergic reaction due to an insect bite or a plant outside. those reactions tend to resolve within 48 hours without treatment. if the swelling becomes too large or if your dog becomes lethargic, take him to the vet in order to get an antihistamine/steroid injection. from your description at this moment i think he is probably fine, but this can change so monitor him closely.

You can cool the area where the sting is with some ice wrapped in a cloth. This will take the pain and reduce the swelling. By tomorrow the area should look normal again. If your puppy starts to vomit, gets breathing problems or appears ill, you will need to take it to a pet ER for treatment.

You should call your vet and give him/her an update. If the hives started after giving the antibiotics then your vet may want to switch to a different antibiotic in case it is an allergic reaction to the antibiotics. Your vet may also want to prescribe a corticosteroid to help treat.

It does look like a bad case of hives. The problem with allergic reactions is that they often get worse, and can lead to breathing difficulties. Due to this, I would take Bruno into an urgent after hours clinic now.

They do tend to swell varying amounts when they get stung by bees, but they don't tend to have severe complications, so I would not worry too much right now. You can safely give one 50mg tablet of benadryl by mouth to help prevent allergic reactions. Just know that this will make him drowsy. An allergic reaction normally happens within the first couple of hours, so if he's doing OK by the end of the day, then he should be fine. If he starts vomiting, you notice his face swell excessively, or he seems to have trouble breathing, then these would be signs of an allergic reaction that needs emergency vet treatment. I hope that helps and Ardie turns-out OK.

Ouch, poor Bongo! You did the right thing by taking out the stinger. Put a cold compress on it for five minutes at a time to help with the pain and swelling. Keep an eye on him. If his paw starts swelling despite the cold compress, he gets hives, he is in pain, or you see signs of anaphylactic shock, rush him into an ER vet immediately. Best of luck, I hope this helps!

On no, poor Nymeria. Some dogs are allergic to bees, and a sign of an allergic reaction is vomiting. I would be concerned since she has vomited five times in two hours, and I think seeing a vet is best for her now. Please take him into an ER vet clinic; if there isn't one in your area, there will be a vet on call for emergencies. The information to reach that vet is found on a clinic's answering machine or website. Best of luck, I hope this helps!
