I have surgery on Monday to get a cyst removed from my side. My mommy is worried b/c she has heard that boxers sometimes have a fatal reaction to a specific type of anesthesia... Is this true or is my mommy just worrying about nothing?

P.S. Please keep me in your prayers that this is just a benign cyst. My mommy keeps having nightmares that I have cancer.

Play?! Let's- PLAY!!!

hug Chase you and your family will be in my thoughts. Good luck to you!

I think you are referring to Acepromazine, I have heard about it and unfortunately did not know about it until AFTER Chewie was neutered.

But everything turned out okay for us.

I would think that most vets are aware of Boxers and Acepromazine, but to ease your mind maybe you should ask them first.

Here is a link with a warning about it (sorry, don't know how else to post it).


Warning on Acepromazine
by Wendy Wallner, DVM

There is one drug commonly used in anesthetic protocols that should not be used in the Boxer. The drug is Acepromazine, a tranquilizer, which is often used as a preanesthetic agent. In the Boxer, it tends to cause a problem called first degree heart block, a potentially serious arrhythmia of the heart. It also causes a profound hypotension (severe lowering of the blood pressure) in many Boxers that receive the drug. Recently, on the Veterinary Information Network, a computer network for practicing veterinarians, an announcement was placed in the cardiology section entitled "Acepromazine and Boxers." This described several adverse reactions to the drug in a very short time span at a veterinary teaching hospital. All the adverse reactions were in Boxers. The reactions included collapse, respiratory arrest, and profound bradycardia (slow heart rate, less than 60 beats per minute). The announcement suggested that Acepromazine should not be used in dogs of the Boxer breed because of a breed related sensitivity to the drug.

This drug is the most commonly prescribed tranquilizer in veterinary medicine. It is also used orally and is prescribed for owners who want to tranquilize their dogs for air or car travel. I would strongly recommend that Boxer owners avoid the use of this drug, especially when the dog will be unattended and/or unable to receive emergency medical care if it is needed.

We brought this up with our vet and he said he doesn't use it. I think there are safer methods that many vets use, so just check with your vet... It is commonly referred to as "Ace" and the 3 vets I've used with my Boxer's all knew what I was talking about when I called it that, and all assured me that they don't (or wouldn't, in 1 case with a vet we only used a couple of times before we found Dr. Arn) use it.

My pups haven't had problems with anesthesia and every one of my dogs has had at least 2 surgeries.

Ah yes, Ace. As long as you ask your vet not to use it, they will generally respect your wishes and make up a different "cocktail" of stuff for your dog. My current vet tries arguing with us every time, but mom stands firm. No ACE on us.

I have surgery on Wednesday and mom is always panicked anytime we are out of her site. So we feel ya here.

I tell my dogs' vet that Ace is NOT to be used. I tried before letting a vet know about my concerns with Ace but he used it any way on my boxer. It cost us several thousands of dollars because of his refusal to use something else. We had "fainting" spells where the dog would get so excited that he would collapse and it appeared that he had "died." Fortunately, he didn't but it was something that affected for almost 10 years. That first night was horrible. Later another I told another vet that I forbid the use of Ace. He thought I was crazy but I was firm. Later he reported to me that he had changed his mind because he lost another dog after using Ace.

Before that I used Ace for another boxer that I had to transport via car 2 hours to a specialist for knee surgery to keep her quiet. No problems but after reading about Ace and the effect on another boxer I now refuse to allow Ace for any reason. There are other drugs that are safe and effective.
