How To Euthanize A Dog With Benadryl

Although most pet parents never want to consider such things, unfortunately, there may come a time in which your dog needs to be euthanized.

This is never an easy pill to swallow for pet parents. Nevertheless, sometimes it’s pretty much the only option.

If you have come to terms with the fact that your dog needs to be euthanized, first of all, it’s OK to feel bad about it.

Secondly, you need to be sure you know exactly what you’re doing before you begin the process, otherwise your dog will suffer (or just find a free clinic to put the dog down).

The following is an overview of the reasons you may need to do this, things to consider before deciding to euthanize your pet, and the steps you need to take.

But before we start, please always consult with your vet if you have any concerns about your dog.

And keep in mind that this website is not a substitute for medical advice for your pet, so we encourage you to consult with your vet before taking the steps of euthanizing your dog at home.  In fact, some shelters even offer free euthanization since it is safer than doing it yourself.

Reasons to Euthanize a Dog

While euthanizing your dog is not always the answer, you may need to do so for the following reasons:

  • Major Behavioral Issues: The main reason you may want to euthanize your dog is that they’re having major issues with their behavior. This is far beyond ripping up your furniture or clothing, rather, more along the lines of your dog acting out in ways that are violent and have seriously injured animals or people for unexplained reasons. This is especially true if the behavior may result in legal liability or criminal issues for you, the owner of the pet.
  • Chronic Uncontrollable Pain: Another major reason to euthanize your dog is that they are in constant, chronic pain that cannot be controlled by the veterinarian or other means. Be sure to get multiple professional opinions before deciding that your dog’s pain is unbearable.
  • Vomiting and Diarrhea: If your dog is constantly vomiting as well as having episodes of diarrhea that has caused massive weight loss, this may be a sign that it’s time to euthanize.
  • No Appetite: If your dog has no appetite for an extended period of time and you literally have to force it to eat, it may be time to euthanize your dog. This is often a sign of chronic illness or could simply be the side effects of old age setting in.
  • Standing Issues: Similarly, if your dog can no longer stand on its own and it is not due to a serious injury, this may be a sign that it’s time to euthanize.
  • Labored Breathing: If your dog has chronic labored breathing, and especially if it’s associated with a bad cough, this may be a sign that you should euthanize.

And for whatever reason, you’ve decided that home euthanasia for the dog with Benadryl is better than letting your vet or local animal hospital handle it. (we really encourage you to find an animal hospital to do this for you!)

Things to Consider

Although there are various reasons why canine euthanasia may be the most suitable option, there are also plenty of things you need to think about before going through with it.

For instance, you should consider the following:

What are your plans for the remains?

One of the top things to consider before euthanizing your dog is what you will do with the remains.

Your options are cremation, burial at home, or burial in a pet cemetery.

How will you mourn?

How you will mourn your pet is often a lesser considered aspect of euthanizing a dog.

No matter how long you’ve had your pet or what they have done, euthanizing them will likely cause grief for days, weeks, months, or even years to come.

Taking time to consider the best ways to mourn beforehand may save you some pain and grief later on. For those who do not handle death well, contacting a professional may be advised.

For instance, you may want to spend time reflecting on your time together by viewing old photos, videos, etc., and listening to peaceful music.

On the other hand, you may want to take a more celebratory approach, quietly euthanize the dog, and have a celebration of life with your family and friends after.

How you do it is entirely up to you.

Who will be present?

Not everyone is capable of handling witnessing a pet being euthanized, and you never want to risk not being able to fully complete the process.

This will cause more harm to the pet as well as everyone who loves the dog.

Therefore, you need to make a plan in terms of who will do the procedure, who will help with the aftermath, and who should be kept far away from the process entirely.

Know the law

Before you go to euthanize your dog with Benadryl, you need to be sure that it is legal in your state.

Some areas have deemed euthanizing dogs as illegal and it may result in fines and other legal repercussions.

Rather than taking a chance and making the situation worse, take the time to research and understand the laws in your area before moving forward.

Does Benadryl Really Work For Canine Euthanasia?

Can you euthanize your dog with Benadryl? The short answer is yes, but you really should not do this to your pet because it can go wrong and cause your pet to suffer more.

You will definitely want to check with a professional before going through with the procedure. If it’s a matter of cost, there are probably free options in your local area that are better option than Benadryl.

Either way, in order to euthanize a dog using Benadryl, you need to give the dog at least three times the standard dosage amount.

Dosage and Steps Euthanize Your Dog With Benadryl

Now that we know about when and why you would want to euthanize a dog with Benadryl, as well as the things to consider before going through with it, here is a list of steps to actually euthanize a dog:

  1. Comfort Counts: As with any medical procedure, you should first make sure that the patient is as comfortable as possible. In this case, make sure your dog is lying in a comfortable position and that they are calm, relaxed, and that you have done everything you can to make sure they can transition comfortably.
  2. Dosage: As mentioned, it takes at least three to four times the recommended dosage to euthanize a dog. The normal dosage of Benadryl for dogs is approximately 1 mg per pound. For example, if your dog is 40 pounds, a normal dosage would be 40 mg. So, if you want to euthanize a 40-pound dog, you would need to give them at least 120 mg of Benadryl.
  3. Get a Professional Opinion: Also, consulting with a professional is always advised. Particularly, working with your vet to determine the proper dosage is highly recommended. This is the best way to avoid causing the dog health issues without putting the dog to sleep. It can also help you avoid trauma that can be caused by such a situation. So, even if you are relatively certain about the dosage you should use, make sure you run it by a professional anyway.
  4. The Process: To be frank, using Benadryl is an inexpensive method of putting your pup to sleep. The overdose of Benadryl will cause the dog to slip into a coma which they will never wake up from.

Overall, euthanizing your dog is obviously no easy feat. No matter what your reasoning is for doing so, you will likely experience grief and sadness as a result of the procedure.

Nevertheless, there are plenty of situations in which euthanasia is the only suitable option for your doggo.

Therefore, you should simply make sure that you have taken the time to properly prepare yourself, your loved ones, and of course, your dog before you decide to go through with the procedure.

Rather than simply allowing your dog to suffer to death, euthanasia can be a very human method of helping to put an end to the pain that your dog is experiencing every hour of the day.

  1. This does not work.
    Lethal dose is closer to 25 mg/kg.
    Your pet will not go to sleep.
    First they will start to shake
    Then they will have seizures
    Then they will have a heart attack
    It’s not quiet.
    It’s not pretty.
    It’s not humane.

    • I like Kevin had no success with Benadryl and had to resort to other methods to finish and it was very painful to all involved. Don’t take chance with a pet you love.

      • What other methods did you have to endure?? My boxer is not in good shape and I hate seeing her suffer and she hates the vet, so I’m thinking of doing this at home where she is more comfortable.

  4. This WILL NOT work and you and your dog will suffer. CALL YOUR VET. Many offer home euthanasia or can refer you to someone who does. If you can’t afford or can’t get to a vet, your local humane society/similar group will be able to help.

  5. Now that we have heard from all the “VETS” I WHO am not a vet had a 15-year-old lab/pit 90lb and had no choice but to do it this way, I used 5 times the normal dose like a friend did with his own. He drifted off to sleep, and it was over, So shame on all these JackOff’s lying to you on here, so the vet can charge his fee while you pet suffers even longer and then get charged for it.

    • Thank you so much, I am going through this now looking for a way, my Babe had a stroke this morning, after months of lovingly taking care of her rear end failing issues, lifting her as she most times could not stand on her own, then getting a very bad UTI, she is almost 15 yrs old and my heart is breaking. I am looking for the dosage to give her of morphine sulphate oral solution, she has lost a lot of weight and is 47 lbs., I have been in contact a few hours ago and am waiting for a response to JustAnswer.com a group of vets. as to the amount to give her. Thank you again for bringing this to light. dcdw
