How much Benadryl can I safely give my dog?
In general, the safe dosage of Benadryl for dogs is 1 mg per pound of body weight, given every 8 to 12 hours as needed. However, this is only a general guideline, and you should always check with your veterinarian before giving your dog any medication.
What happens if you give Benadryl to a dog?
Dogs are highly sensitive to antihistamines. Benadryl, or diphenhydramine, is an over-the-counter antihistamine that can be used to treat allergies in humans. However, dogs should not take Benadryl unless directed by a veterinarian.
The most common side effect of Benadryl in dogs is drowsiness. Benadryl may also cause dry mouth, constipation, urinary retention, and rapid heart rate. In severe cases, Benadryl can cause seizures.
If your dog has any of these side effects, stop giving them Benadryl and call your veterinarian.
If you think your dog may have allergies, talk to your veterinarian about the best course of treatment. Benadryl may be appropriate for some dogs, but it is not a cure-all for allergies.
Will Benadryl make my dog sleepy?
Yes, Benadryl can make your dog sleepy. The active ingredient in Benadryl is diphenhydramine, which is an antihistamine. Histamine can cause itching, sneezing, and runny nose.
It is also a neurotransmitter, which means it can affect the brain. Diphenhydramine works by blocking histamine from binding to its receptors. This can cause drowsiness in both humans and dogs.
Can I give my dog 50 mg of Benadryl?
Yes, you can give your dog 50 mg of Benadryl, but it is not recommended. The reason being, Benadryl is an antihistamine and histamine plays an important role in the immune system. So, while giving your dog Benadryl may help with allergies or itchiness, it can also weaken their immune system.
Does Benadryl Work?
Benadryl killed my dog
I was out of town for the weekend and left my dog, Benny, in the care of my neighbor. When I got home, I noticed Benny was acting strange. He was listless and uninterested in his food or water.
I thought maybe he was just tired from being left alone, so I didn’t think much of it.
The next day, Benny was still acting strange. He wouldn’t move, and he wouldn’t eat or drink.
I took him to the vet, and they did some tests. They told me that Benny had been given Benadryl and it had killed him.
I can’t believe that something as simple as Benadryl could kill my dog. I trusted my neighbor to take care of him, and she killed him. I would never give my dog Benadryl again, and I would never leave him in her care again.
If you have a dog, please be careful giving them Benadryl. It may seem like a harmless over-the-counter medication, but it can be deadly.
Conclusion
Yes, it is safe to give dogs Benadryl. The recommended dosage is 1 mg per pound of body weight, given every 8-12 hours as needed.
