For example, a pound dog would get 50 milligrams of Benadryl. Brand name and generic forms generally come in milligram tablets, so that pound dog would get two tablets at a time. Avoid the adult formula of liquid Benadryl, as this often contains alcohol, which is toxic to dogs.
As with any flavored human medication, always check the inactive ingredients for xylitol, a sweetener that is extremely toxic to dogs. Do not give your pet any medication or any other substance containing xylitol. Do not give Benadryl if your dog has a heart condition particularly high blood pressure , glaucoma, seizures, bladder issues particularly an obstruction , or lung disease. If symptoms persist even after giving Benadryl, contact your vet.
Swelling of the throat is an emergency and requires immediate intervention with injectable medications that will work faster than a pill given by mouth. If you find yourself giving Benadryl to your dog on a regular basis, discuss the symptoms you see and the frequency with your veterinarian.
While Benadryl may be working well to address the symptoms, there may be other medications that can more effectively address the underlying cause of those symptoms. Benadryl can be given with or without food. Find out when Benadryl is effective and safe and when your dog needs a different treatment. Here are a few things you should keep in mind before giving your dog Benadryl. You might have heard that Benadryl can be given to dogs to help with travel anxiety or dogs that are scared of fireworks and thunderstorms.
Benadryl has some efficacy in the prevention of motion sickness in dogs and as a mild sedative, but the effects are not the same as with people. Some dogs and cats can actually have the opposite reaction to Benadryl, causing hyperactivity instead of sedation. If your dog has anxiety, or they get nervous while traveling, talk with your veterinarian to determine a course of treatment. Benadryl is an antihistamine that blocks the H-1 receptors on smooth muscle and blood vessels.
Taken orally, Benadryl can be mild to moderately effective for dogs experiencing mild allergic symptoms. Vets commonly use it to treat environmental allergies and allergic reactions to insect bites or stings.
It can also be used as a pre-treatment for possible vaccine reactions. But if your pet is having an acute allergic reaction with facial swelling or difficulty breathing, take them straight to the vet.
Many allergic diseases also require a combination of allergy medicine and treatment of underlying infections. By and large, Benadryl is very well-tolerated in dogs, with few side effects and a low risk of overdose.
It remains one of the safest over-the-counter drugs that veterinarians frequently reach for and recommend for their canine patients. Benadryl is a brand name for the drug: diphenhydramine, which is an antihistamine. Antihistamines work by blocking the effects of the naturally occurring chemical histamine in the body. Histamine is often produced during an allergic reaction. Benadryl is used for many different reasons:.
Just like humans, antihistamines can be used to treat similar allergic reactions in dogs. The important aspect is to know whether your dog is having an allergic reaction or has chronic seasonal allergies. If you notice nasal discharge, coughing, or inflamed, reddened eyes, these can all be signs of a respiratory infection. It all comes down to getting a comprehensive evaluation from your vet. If your fur baby is indeed suffering from an allergic reaction, your vet may recommend daily doses of Benadryl for dogs.
As we mentioned, the below signs and symptoms of allergies in dogs can also be indications of more serious illnesses. However, if your vet notices these common symptoms, they may recommend treating them with an antihistamine like Benadryl. Some of the signs and symptoms of allergic reactions in dogs include:. There are many things in your home that may trigger an allergic reaction in your dog.
Some of these may include:. In addition to removing items from your house that might be causing allergies, the best advice is to clean thoroughly, wash the bedding often, and clean with all-natural products with no chemicals. Your vet may recommend Benadryl for dogs who have chronic allergic reactions to their environment. On the other hand, food allergies will be dealt with by changing food brands or styles, not with Benadryl.
