The best over-the-counter allergy medicine for dogs is a non-sedating antihistamine. You should look for one with little or no side effects, as well as one that is easy to administer. The best options are either a liquid form of the medication or a chewable tablet.

Allergies in dogs can be quite common, especially if they live in an area where there are many trees, grasses, and other plants in bloom. If your dog has allergies, it can lead to inflammation of its skin and ears. It may also result in sneezing and itching which can be very uncomfortable for your pet. They may begin scratching their skin excessively which can cause them further problems such as open wounds or infections.

If you notice any symptoms such as scratching or paw licking from your pet then it is important that you take them to see a vet who will be able to diagnose what type of allergy they may have so they can start treatment straight away before any further damage is done.

The best over-the-counter allergy medicine for dogs can be found in your local pet store. For example, Claritin is a common medication used to treat allergies and it’s safe for use in dogs. Each person has different symptoms when they’re having an allergic reaction. Some people develop a stuffy nose and sneeze, while others get hives or rashes all over their bodies. In dogs, it can be difficult to tell what part of their body will react because most of them are furry.

What Is Over The Counter Allergy Medicine?

Over-the-counter allergy medicine is a drug used to treat seasonal and perennial allergies. Over-the-counter allergy medicine is available over the counter and does not require a prescription. It may be in the form of tablets, capsules, liquids, or creams that are applied to your dog’s skin.

Benefits Of Over The Counter-Allergy Medicine For Dogs

Here are the benefits of OTC allergy medicines for your dog:

  • Reduce inflammation, itching, and sneezing.
  • Improve mucous membranes (reduce runny nose).
  • Reduce coughing and wheezing.
  • Relieve congestion in their nasal passages and airways that can lead to difficulty breathing.

Effects Of Over The Counter-Allergy Medicine On Dogs

Over-the-counter allergy medicines are administered to dogs in a variety of ways. For example, some can be given as a pill that is swallowed whole, while others come in liquid form and need to be given through the mouth or nose. A few types can even be administered as eye drops. Once you’ve determined how your dog will receive their medication, it’s time to determine how much relief it’ll receive from it. While some dogs may experience immediate relief from taking over-the-counter allergy medicine for dogs, others may need to continue using it for several days before seeing any improvement at all. If you notice no change after several days of administering the medication twice daily (or three times daily if instructed by your veterinarian), stop giving it altogether until further instructions from your veterinarian have been received.

How Does Over The Counter Allergy Medicine For Dogs Work

Over-the-counter allergy medicine for dogs works in the same way as it does for humans. It is a medication that is used to treat allergy symptoms in dogs, such as itching and rashes. It works by blocking histamine and other substances that cause allergic reactions.

When To Use Over The Counter Allergy Medicine For Dogs

When you should administer over-the-counter allergy medicine for dogs:

  • When your dog is experiencing allergy symptoms, including sneezing, runny nose, and red eyes.
  • Before you go out for a walk or when you are about to go to the vet.
  • Before going to the groomer or before going to the dog park (if they have allergies).
  • Before heading off on an adventure at the dog beach or any other place where there may be allergens that could set off their allergies.

How To Use Over The Counter Allergy Medicine For Dogs

Over-the-counter remedies for allergies are a great way to help your dog feel better, but you should always follow the instructions on the label. There are some over-the-counter medications that can be unsafe for your dog, so make sure you only use those that have been approved by your vet. Once you’ve picked a medication and have it ready to administer, please note these important points:

  • Read the label carefully. You’ll want to make sure that whatever product you choose is appropriate for your dog’s age and weight, as well as any other concerns he may have (such as poor kidney function).
  • Follow all dosage recommendations exactly. If there isn’t enough information on how much medicine should be given at once or how often it should be given, ask a veterinarian before proceeding with treatment. They’ll know best how much to give their patients based on breed size and other factors related to health status.”

How Long To Use Over The Counter Allergy Medicine For Dogs

If your dog has been diagnosed with an allergy, it’s important to consult your vet about the best course of treatment. Over-the-counter allergy medicine is only a short-term solution, so you should always be sure to check with your vet before using any medication on your dog. There are many different options available, including antihistamines and steroids, which can be used alone or in combination with other medications.


Claritin is a non-sedating antihistamine that has been proven effective against seasonal and common allergens, including grasses, weeds, dust mites, and fleas. In addition to offering relief from sneezing and itchy eyes, Claritin also helps reduce ear infections in some pets by reducing irritation of the inner ear canal.

Claritin comes in tablet, chewable and liquid forms for dogs as well as a fast-dissolve tablet form for cats. All forms are available at your local pharmacy or pet supply store.

Claritin can be used safely by dogs with mild to moderate allergies who have not had an allergic reaction in the past 24 hours due to previous use of Claritin or other antihistamines containing loratadine or desloratadine (the active ingredients) such as Levocetirizine (Xyzal), Cetirizine hydrochloride (Reactine), Desloratadine (Clarinex)


Benadryl is a common over-the-counter allergy medicine that can be used to treat mild allergies in dogs. It’s also sometimes used to treat skin irritations, such as those caused by insect bites and stings. Benadryl acts as an antihistamine, which means it blocks the effects of histamine on your dog’s body and helps reduce the symptoms of their allergy.

Benadryl is a prescription drug in some countries (including Australia) but is available freely over the counter in others. In some countries (such as New Zealand), it’s only available by prescription. If you live in one of these places where Benadryl isn’t easily accessible, talk to your doctor about what other options are available for treating your dog’s allergies.

Because Benadryl affects how much sleep your dog gets at night, which isn’t usually an issue for most people, it can make them drowsy during the day if they take too much at once or don’t follow directions carefully enough when taking their medicine every day. Be sure not to give any human medications intended exclusively for humans unless they’re prescribed specifically by veterinarians; this includes liquid multivitamins with added calcium because they might contain too much vitamin D toxicity levels without knowing exactly how much each person needs based on age/weight etcetera.”


Zyrtec is a non-sedating antihistamine that helps your dog breathe easier by blocking the effects of histamine. The medication is available in chewable tablets and a liquid form, making it easy to administer to picky pups.

Zyrtec is prescribed for the treatment of seasonal allergies and can be used year-round if your dog has allergy symptoms year-round. Zyrtec is safe for dogs over 6 months old, but because it’s available without a prescription, you should always consult with your vet before administering medication to your furry friend.


How to use Xyzal

The recommended dose for dogs is 1 mg per pound every 12 hours. The medicine can be given either with or without food. If your dog has a serious reaction, contact your veterinarian right away.

Side effects of Xyzal

In rare cases, dogs may experience side effects such as vomiting or diarrhea while taking this medication. If you notice any changes in your pet’s behavior while they are taking it, contact your veterinarian immediately so that they can make any necessary adjustments to the dosage or treatment plan.

How long should I use Xyzal?

If you have determined that an allergy medication is necessary for your pet and want something that is effective yet safe for regular use over an extended period of time, then Xyzal might be what you are looking for. However, if it does not appear to help with their symptoms after a few weeks then talk with your vet about other options (such as switching medications). Dosage: The recommended dose for dogs is 1 mg per pound every 12 hours but consult an expert before using this drug on cats because some veterinarians believe there could be adverse reactions due to differences between these species’ metabolisms/reactions towards certain drugs.”


Quercetin is an antioxidant that can help treat allergies. Specifically, it can help reduce inflammation and the number of histamine receptors in your dog’s body, which will help to reduce the production of histamine. This can have a positive effect on their overall allergy symptoms.

Quercetin can also be used to treat seasonal allergies in humans, but there’s not enough research yet to determine whether or not it’s safe for pets at this time.

Dosage Of Application

There are several factors that affect the dosage of the application of over-the-counter allergy medicine for dogs. Some of them are:

  • Size and age of the dog
  • Weight of dog
  • The severity of allergy symptoms
  • Type of allergy (seasonal, food, insect)

Overdose Symptoms

Overdose symptoms of over-the-counter allergy medicine for dogs

The most common overdose symptom of over-the-counter allergy medicine for dogs is vomiting. However, if you notice any other symptoms such as lethargy, weakness, or dizziness after giving your dog a dose of Benadryl, contact your veterinarian immediately.

Overdose symptoms of over-the-counter allergy medicine for cats

If your cat vomits or has diarrhea after taking Benadryl, call your veterinarian right away because it can be an indication that they have overdosed on this medication. If they are experiencing any other symptoms such as lethargy or weakness, take them to an emergency clinic right away.

Overdose symptoms of over-the-counter allergy medicine for humans

Overdosing on Benadryl could cause difficulty breathing and low blood pressure which may lead to unconsciousness in some cases. These are severe side effects that require immediate medical attention from a doctor. In addition to these severe side effects, another possible complication of taking too much Benadryl is confusion and hallucinations. If any of these overdose symptoms occur with excessive dosing then seek medical attention immediately; do not wait until tomorrow.

In Conclusion

By using this medication you will be able to reduce symptoms, as well as prevent them from getting worse. When used correctly and under the guidance of a veterinarian, they can be very safe and effective.
