Benadryl for dogs reviews

Benadryl (diphenhydramine) is a medication that relieves symptoms of allergies. It is available in both liquid and tablet form and comes in different strengths.

Benadryl can be given in cases where the dog has an allergic reaction or when he’s having motion sickness. It will help calm the dog down and make him more comfortable.

When given orally, it can be taken at any time of day, but it’s usually taken in the evening or before bedtime.

There are some side effects with Benadryl for dogs, but they’re usually mild and go away after a few hours. These include:

  • Drowsiness
  • Vomiting
  • Diarrhea
  • Drooling
  • Dry mouth
  • Blurred vision

Benadryl may also cause hypotension (low blood pressure), arrhythmia (irregular heartbeat), and seizures in some dogs if they take too much of it at once.

Benadryl is an over-the-counter drug, meaning that it is sold without a prescription. This means you can buy it at any pharmacy without having to see your vet first.

If your dog has any health problems that make it unsafe for him to take Benadryl, talk with his veterinarian about alternative treatments.

Many people who have pets with allergies have found that it is very important to keep Benadryl on hand at all times.

“My dog is allergic to everything and has had hives, itchy skin, and other medical issues over the years. I have tried every natural remedy on the planet and nothing seems to work. She is almost 13, so I decided to try Benadryl for dogs. Her itching has gone down tremendously since she’s been on this medication as well. I love that Benadryl does not have any serious side effects. It’s easy to administer and very affordable compared to other medications out there that do not work as well!”

“I have a 3-year-old Shih Tzu who is allergic to grass. She gets very itchy if she goes on walks in the park. After reading some of your reviews, I decided to give Benadryl a try. The difference is amazing! She was able to go for a walk without scratching and then she slept all night long!”

“My dog is a rescue and has had allergies for years. I have tried many different things to help her feel better, but nothing worked until I found Benadryl for dogs. It works wonders! She is not as itchy and her coat is much shinier. I highly recommend this product for any dog who suffers from allergies or motion sickness!”

“I have a dog who is allergic to grass and pollen. She would get very itchy, runny nose, and sneeze. I found Benadryl at my local store and gave her 2 tablets after her morning meal. The symptoms went away within 30 minutes! I can now take her out in the yard without worrying about her scratching herself raw! Thank you so much!”

“I have a 14-year-old poodle and we were getting him Benadryl every time he got motion sickness. He would get so sick that I would have to take him out of the car and walk him around for about half an hour until he felt better. We decided to try Benadryl because it didn’t contain any harmful ingredients. My dog loves it! He is no longer bothered by motion sickness at all.”
