Zyrtec vs Claritin: Is Claritin or Zyrtec Better for Dogs?

There are a lot of options when it comes to choosing over-the-counter allergy medication for your dog. Zyrtec and Claritin are two of the most common choices, but which one is better?

Claritin vs Zyrtec for dogs with allergies

Zyrtec and Claritin

Claritin and Zyrtec are both antihistamines used to treat allergies in dogs. They work by blocking histamine receptors in the body, which reduces allergy symptoms like itching, sneezing, and watery eyes. Both medications can be used alone or with steroids if necessary.

If you’ve decided to try one of these medications, start with the lowest dose possible and work up slowly until you find the most effective dose for your dog.

Both medications come in chewable tablet form and liquid form (for those dogs who won’t take pills). Make sure you get the correct dosage for your dog’s weight.

Zyrtec for dogs reviews

Zyrtec for dogs has been used to treat symptoms of allergies in dogs for over 15 years. The active ingredient is cetirizine hydrochloride, which is a type of antihistamine.

Zyrtec is available in tablets and chewable tablets, as well as in liquid form. The dosage depends on the size of your dog and how severe their allergies are.

The manufacturer recommends giving the medication with food to minimize side effects, but some customers have reported that their pets still experience some side effects, including vomiting and diarrhea.

Other reported side effects include decreased appetite, lethargy, and dry mouth or nose. The product also contains lactose, so it may cause stomach upset in animals that are lactose intolerant.

Reviewers say that Zyrtec works best on itching caused by food allergies or environmental allergens, such as pollen and dust mites. It can also be used to treat some types of dermatitis (skin inflammation).

“I have been using this product for years. It has never failed to work and is one of the few things that works on my dogs. I have a German Shepherd and an Australian Shepherd, both with very sensitive skin and allergies. I have tried many other products that did not work, but this one does.” – Amazon Customer

“My dog had an allergic reaction to fleas and his skin irritation was so bad that it was spreading down his back onto his tail area. I decided to try Zyrtec because it is supposed to be safe for cats as well as dogs. He is now completely healed and back to his old self.” – Amazon Customer

“My dog has been taking Zyrtec for about two weeks now, and it seems like he’s doing better! He’s not scratching as much and his eyes aren’t red anymore! I’m so glad we found something that works for him!” – Amazon Customer

Claritin for dogs reviews

Claritin for dogs is a popular over-the-counter medication that can help to relieve the symptoms of seasonal allergies. It is available in an oral suspension and tablet form, as well as a topical solution.

Although most pets tolerate Claritin well, some may experience side effects such as vomiting, diarrhea, and loss of appetite. If your pet experiences these side effects, stop giving them the medication and contact your veterinarian right away.

Reviewers say that Claritin, which is also available in a chewable form, helps alleviate allergies and improves their dogs’ quality of life.

“My dog has been on Claritin for several years,” one reviewer wrote. “I’ve tried other brands but she always goes back to this one.”

Another echoed this sentiment: “Our vet recommended this product and it works great. Our dog has been on it for a couple of years now and it has helped with his allergies tremendously!”

One person reported that her dog’s skin problems cleared up once she started using the medication. Another said it helped her dog sleep through the night without waking up to scratch his ears or face.

“I use this product on my two dogs and it works great! I tried other allergy medications but they were too strong for my little dogs.”

“My dog had been scratching a lot and losing hair, so I decided to try this product. He seems to be doing better already, so I will continue using it.”

“My dog has allergies and I tried many products but this one works best. It is not too expensive, it’s easy to use and my dog doesn’t mind taking it every day.”

Is Claritin or Zyrtec better for dogs?

Some dogs respond better to Zyrtec than Claritin. It’s important to try both medications before making a final decision about which drug works best for your pet.

Some dogs are allergic to both types of medication, while others may be sensitive only to one drug. The only way to know for sure is by giving each medication a try and monitoring your dog’s symptoms afterward.

How long does it take for Zyrtec or Claritin to work on dogs?

The answer is different for each dog. Some dogs get relief within 30 minutes, while others may take up to 1 or 2 hours for the antihistamine effect to start.

How much Zyrtec can I give my dog?

The usual dose of Zyrtec is 0.5 mg per pound of dog’s weight, and the maximum per dose is 20 mg.

Zyrtec dosage for dogs
Dog’s weight Zyrtec (cetirizine) dosage
5 lbs ½ of a 5 mg tablet
10 lbs one 5 mg tablet
20 lbs one 10 mg tablet or two 5 mg tablets
50 lbs two 10 mg tablets
80 lbs two 10 mg tablets

How much Claritin can I give my dog?

The correct dosage of Claritin depends on the weight and health condition of your dog. It is important that you follow instructions closely in order to avoid overdosing and causing harm to your pet.

Dog’s weight Claritin (loratadine) dosage

Best antihistamine for dogs with skin allergies

There are many different options when it comes to choosing an antihistamine for your dog. Here are some of the most popular choices:

  1. Benadryl
  2. Zyrtec
  3. Claritin
  4. ChlorTrimeton
  5. Tavist

There are several treatments available for atopic dermatitis in dogs, including antihistamines, steroids, and immunosuppressants. However, there isn’t one type of medication that works best for all dogs with this condition — it depends on their symptoms and the severity of their condition.

The most common side effects associated with antihistamines are drowsiness and decreased appetite. Severe reactions can occur in any dog, but they are more likely in dogs with kidney or liver disease, heart disease, or seizures.

It’s important to consult with a veterinarian before giving your dog any medications. If your pet has a pre-existing condition or you’re unsure how much medication he needs, don’t attempt to give him any over-the-counter drugs without consulting with a vet first.

Can I give my dog Zyrtec and Benadryl at the same time?

It’s important not to use both drugs at once because they may produce unwanted side effects if you do so. Make sure that you speak with your vet before giving either drug to your dog so that they can advise you on how much medication is safe for them to take per day and how often they should take it.

If you are having trouble controlling the itchiness from allergies, consider switching your dog’s food to hypoallergenic food or adding immune system & allergy supplements for Dogs to your pet’s diet.

Conclusion of Claritin vs Zyrtec for dogs

Zyrtec is a great antihistamine for dogs, but it’s not perfect. The side effects are mild and can be managed if you know what to expect. It also has a bit quicker onset of action than Claritin, although both can cause side effects in some dogs.

If your dog has mild to moderate seasonal allergies, then Zyrtec may be a good option for them. If they have severe allergic reactions or itchy skin year-round, then I would recommend trying another medication first.

In conclusion, both medications have their own benefits as well as side effects. If your dog has any known health issues or is taking other medications that may interact with antihistamines, make sure you talk with your vet before giving them either of these drugs.
