What is Benadryl used for dogs?

Benadryl is a well-known antihistamine that can be used to relieve the symptoms of allergies in dogs. It can also be used to treat motion sickness and anxiety.

Benadryl works by blocking the effects of histamine in the body. This will reduce itching, sneezing, and coughing, as well as decrease swelling.

Benadryl is available in several different forms, including tablets, chewable, and liquid that you can give your dog directly or mix into food or water. Follow the dosage instructions on the product label carefully, as they will vary depending on your dog’s weight.

Keep in mind that Benadryl is not intended to be used as a long-term treatment for dog allergies. Your dog will need additional medication from your veterinarian if she continues to experience allergy symptoms after using Benadryl for a few days.

Benadryl is safe to use on dogs of all ages, but it should not be given to pregnant or nursing dogs. In addition, Benadryl must not be given to dogs with bladder or intestinal obstruction, glaucoma, elevated thyroid hormone, or high blood pressure.

Benadryl can interact with antidepressants, so you should talk to your vet about whether Benadryl is safe for your pet if he has been prescribed one of these medications.

Benadryl for dogs reviews

The Benadryl reviews are overwhelmingly positive. In fact, most pet owners said they were satisfied with Benadryl and made it sound like it was life-changing for their pets.

“I am so glad I found Benadryl. My dog has been suffering from anxiety for a long time and nothing has worked until now. He is a very hyper dog and gets excited easily, but this medication has really helped calm him down. I would highly recommend this to anyone who needs help with their dog’s anxiety.”

“It’s a really great product. I am very satisfied with it. My dog is sleeping better than ever before, and he has no more trouble with his allergies. He also seems to have a better appetite. I highly recommend Benadryl.”

“I have been using Benadryl for my dog for about 2 years. He has allergies and always had problems with his ears. He is a very active dog, but his allergies got worse as he got older. I started giving him Benadryl and it seemed to help.”

“This is a great medication that has helped my dog so much. I have been using this for a few weeks and it seems to be working well. My dog has allergies and he used to get sneezing every single time he got out of the car or went outside. He would also scratch his eyes and ears trying to stop the itchiness. I switched him to Benadryl, which is an antihistamine drug that reduces itching. He has stopped scratching his eyes and ears! He also has not had any more sneezing attacks since we started using Benadryl on him! I highly recommend Benadryl if you have a pet with allergy problems!”

What are the side effects of Benadryl for dogs?

Benadryl may cause side effects in some dogs, including:

  • Drowsiness
  • Vomiting
  • Diarrhea
  • Constipation
  • Dry mouth
  • Excessive thirst
  • Urinary retention
  • Excessive drooling
  • Rapid breathing
  • Increased heart rate

How long does it take for Benadryl to work on dogs?

It can take anywhere between 1 to 2 hours before you start noticing a positive effect from taking Benadryl.

It takes some time for Benadryl to hit your dog’s system, enter his bloodstream and then act on the receptors that trigger itching in his body. So don’t be alarmed if you notice no change after an hour or two; it may take a while longer until you see something happen.

Can I give my dog BENADRYL® Allergy Plus Congestion?

You should not give your dog BENADRYL® Allergy Plus Congestion because it contains the decongestant pseudoephedrine, which is not safe for use in dogs and could potentially be fatal.

Pseudoephedrine causes the blood vessels to constrict, which leads to increased blood pressure, rapid heartbeat, and difficulty breathing.

Is there an alternative to Benadryl for dogs?

There are several medicines that can be used to relieve the symptoms of allergies in dogs. Each medicine acts in a slightly different way, and some work better for certain dogs than others.

  1. Cetirizine (Zyrtec)
  2. Fexofenadine (Allegra)
  3. Loratadine (Claritin)
  4. Clemastine (Tavegyl)
  5. Chlorpheniramine (ChlorTrimeton)
  6. Cyproheptadine (Periactin)
  7. Hydroxyzine (Atarax)
  8. Terfenadine (Seldane)
  9. Trimeprazine (Temaril-P)

Conclusion of Benadryl for dogs

Benadryl has proven to be safe and effective for dogs. However, it should not be used as a substitute for veterinary care. The best way to keep your pet healthy is by visiting your veterinarian regularly and learning about their health needs.

Many people will give their dogs a small dose of Benadryl as a temporary fix for allergies or anxiety, but it’s important to know that long-term use of the drug is not recommended and should only be used if prescribed by your veterinarian.
