How to Treat Allergic Reactions in Dogs

If your dog is having an allergic reaction, you should contact your veterinarian immediately. Do not attempt to treat your dog’s symptoms without first consulting a professional. Before calling the vet, be sure to have the following information ready:

  • what type of allergy or allergic reaction your dog is experiencing
  • how long has it been since the onset of their symptoms?
  • has there been any change in their behavior? (like eating less or being more lethargic than usual)

Once you’ve gathered this information, call and schedule an appointment for your pup as soon as possible. It’s also important to keep small objects like buttons and bobby pins in places where your dog cannot reach them so that they don’t try to chew on anything harmful.

Allergic reactions can be easily treated but all dogs are different so consult with your vet before treating an allergic reaction.

It’s important to note that allergic reactions are not the same for every dog. Some dogs can experience anaphylaxis, which is a sudden and potentially fatal response to an allergen. If your dog has experienced an allergic reaction before, you may want to consult with your vet about taking preventive measures.

Allergic reactions can be dangerous, so if you notice any symptoms of one in your pet, contact your local animal emergency center immediately.

If your dog is having trouble breathing, seek veterinary attention immediately.

If your dog is having trouble breathing, seek veterinary attention immediately. This may be a sign of anaphylaxis. If you suspect that your dog is having an allergic reaction, take them to the vet as soon as possible.

If your dog is having a mild allergic reaction (like hives or “swelling”), stick to Benadryl.

This is a common over-the-counter medication that you can buy at any pharmacy. While it’s safe for dogs, it does have some side effects that might make your dog uncomfortable.

The most common side effect of Benadryl is drowsiness, so if your dog has been running around all day and now won’t stop yawning, this could be why! You should also be aware that Benadryl can cause nausea and upset stomachs in some dogs. Lastly, there’s the possibility that Benadryl could cause rashes or other skin reactions—so if your dog starts scratching himself incessantly after taking the medication (or even before), this could be an indication that he’s allergic to something else in his environment (and not just food allergies).

Consult a veterinarian about the best dose of Benadryl for your dog.

If you’re concerned that your pet may have an allergic reaction, it’s best to consult with a veterinarian. The vet can prescribe a proper dose of Benadryl, which is the most common medication used to treat allergic reactions in dogs.

Cool baths can help soothe your dog’s itching.

Cool baths can help soothe your dog’s itching.

When bathing your dog, use cool water and a shampoo designed for dogs. Make sure to thoroughly rinse all of the shampoo out of his or her fur because some shampoos can cause allergic reactions themselves. Use a soft brush to gently stroke your dog’s coat while you wash him or her; this will help soothe the itching. After bathing and drying off with a towel, blow dry any remaining moisture from the fur with warm air on low speed.

If you notice that these steps are not helping your dog sufficiently, seek veterinary attention immediately as he may be experiencing anaphylaxis (a severe allergic reaction).

Use a soft brush on your dog if they are itching.

If your dog is itching, it’s time to brush. Brushing will help calm them down and get rid of any irritations that might be bothering him. It’s especially important to use a soft brush on your dog if they have allergies, as the bristles on certain types of brushes may cause irritation or pain.

To start, begin by brushing his skin with the soft side of the brush. Work slowly in circular motions to soothe his skin and make sure you cover every inch from head to tail. Next, flip over to the other side of your tool and use it gently on his fur (again in slow circular motions). This will remove any loose hairs or dander that could be causing problems for him when he scratches at himself due to allergies.

Do not give human medications to dogs without consulting a veterinarian.

The body metabolizes drugs differently in humans than it does in dogs, and some medications that are safe for people can be fatal for dogs. Some common medications may be dangerous if given to pets. Before administering any type of medication, always consult your veterinarian first.


In the end, it’s important to remember that allergies are not uncommon in dogs, and they can be treated with the right care. Make sure to consult your veterinarian before giving your dog any medications, and make sure you keep human medicine well out of their reach. If you keep these things in mind, an allergic reaction need not be a big deal for your pup!
