Is your dog suffering from seasonal allergies? Just like people dogs can be affected by pollen or other things found in their environment.
If there are trees blooming near your house and your dog is sneezing, the most likely the cause of your dog’s sneezing and watery eyes can be due to allergies. Many people will wonder if they can safely give their dog allergy medication at home just like they take it.
Claritin and Zyrtec are safe treatments to give to a dog to help control mild allergy symptoms. These medications will help with very mild signs while more severe allergies may require prescription allergy medication from your veterinarian.
As always, you should check with your veterinarian first before giving your dog any new medications. There are also some side effects that you need to look for and sometimes you need to avoid giving these medications and see your vet instead.
Let’s take a further look to better understand how to dose these medications for your dog as well.

Before jumping straight into giving your dog allergy medicine, it’s worth verifying that allergies are the actual issue!
Common signs of allergies to see in dogs are:
- Clear discharge from nose
- Runny eyes
- Mild cough

If you notice any of these signs, you can assume your dog has allergies. Your vet can help you determine if these signs are caused by allergies or something more serious.
If your dog’s allergies do not quickly improve, a vet visit is always best.

Both of these medications are antihistamine medications that can be used for allergies, itchy skin, or sneezing. Antihistamines block the histamine receptors in the blood vessels, tissues, or lungs that cause your dog to have signs of allergies.

If you do not treat these allergies in your dog, then your dog can develop a secondary skin infection. This can cause hot spots or open wounds that will need to be treated.
In severe cases of allergies, your dog may develop hives or go into anaphylactic shock. This could be life-threatening and very dangerous.
What are the side effects of Zyrtec or Claritin?
Some dogs can have adverse effects from taking Zyrtec or Claritin.
