Chemo Killed My Dog?

When I searched online ”Chemo killed my dog”, I read this following heart-breaking story in a canine forum.

I had to decide to put my dog down. She was suffering and I couldn’t stand to see her in pain anymore. The cancer had spread throughout her body and the chemo wasn’t working. I made the appointment with the vet and took her in for her last visit. No one ever thinks that their beloved pet will be the one to succumb to cancer. But, for too many dog owners, this is a heartbreaking reality. Just like humans, dogs can get cancer. And while there are treatments available, such as chemotherapy, often times these treatments are just as tough on the dog’s body as the cancer itself. In fact, chemo killed my dog. She was a beautiful golden retriever who was only six years old when she was diagnosed with lymphoma.

We tried everything to save her, but in the end, the chemotherapy just took too much of a toll on her little body and she passed away. It’s been almost a year since she died, and I still miss her every day. She was my best friend and constant companion. Losing her has been incredibly hard, but I take comfort in knowing that she is no longer suffering. If your dog has cancer and you’re considering treatment options, please keep my story in mind”.

This is truly a sad story. But can chemotherapy kill a dog? We will answer this question along with other things related to chemotherapy and dog. Let’s start with the most burning question:

Can Chemotherapy Cause Death in Dogs?

There is no easy answer for whether chemotherapy can cause death in dogs. While chemotherapy has been shown to be an effective treatment for cancer in dogs, it is also associated with several risks and side effects that can be potentially fatal. Whether to pursue chemotherapy as a treatment option for your dog should be made after consulting with your veterinarian and considering all the potential risks and benefits.

Is Chemo Hard on a Dog?

Chemotherapy is a cancer treatment that uses drugs to kill cancer cells. Chemotherapy can be given intravenously (by IV), orally (in pill form), or topically (as a cream). Chemotherapy is often used in combination with other treatments, such as surgery and radiation therapy.

The side effects of chemotherapy vary depending on the type and dose of drugs given and how long they are taken. Short-term side effects include nausea, vomiting, loss of appetite, mouth sores, hair loss, fatigue, and increased risk of infection. Long-term side effects may include anemia, leukemia, heart problems, kidney problems, and fertility problems.

Chemotherapy can be hard on a dog’s body. The most common side effects are vomiting and diarrhea. Other side effects may include loss of appetite, weight loss, lethargy, and easy bruising or bleeding.

These side effects usually go away when the treatment is finished.

How Long Do Dogs Live After Chemotherapy?

Chemotherapy is a common cancer treatment for dogs. It can treat many types of cancer, including lymphoma, leukemia, and sarcomas. Chemotherapy can be very effective in treating cancer, but it also has some side effects.

One of the most common side effects of chemotherapy is vomiting. Dogs may also experience diarrhea, loss of appetite, and fatigue. The time that a dog lives after chemotherapy will vary depending on the type and stage of cancer being treated, as well as the dog’s overall health.

However, most dogs live for several months to years after starting chemotherapy.

Is It Worth It to Do Chemo on a Dog?

There is no one answer to this question as it depends on each individual dog and their specific situation. In general, chemotherapy can be an effective treatment for dogs with cancer, but it is not without risks. The decision of whether or not to pursue chemo should be made after careful consideration and discussion with your veterinarian.

Pros And Cons Of.Chemo for Dogs

There are a lot of factors to consider when deciding to pursue chemotherapy for your dog. The pros and cons of chemo for dogs can be difficult to weigh, but it’s important to consult with your veterinarian and get as much information as possible before deciding. Here are some things to keep in mind:


1. Chemotherapy can be effective in treating cancer.

2. It can give your dog more time with you and your family.

3. It may improve your dog’s quality of life during treatment.

4. There are often less side effects with chemotherapy in dogs than there are in humans.

5. Chemotherapy is often less expensive than other cancer treatments like radiation therapy or surgery.


1. Chemotherapy can have serious side effects including vomiting, diarrhea, loss of appetite, fatigue, and hair loss.

2. It can be hard on your dog’s body and make them feel very sick during treatment.

3) There is no guarantee that chemotherapy will cure cancer–it may only extend your dog’s life by a few months or even weeks.

4) Cancer cells can sometimes become resistant to chemotherapy over time , so additional rounds of treatment may be necessary.

5) The cost of chemotherapy can add up over time, especially if multiple rounds are needed.

Dog Chemotherapy Success Rate

There are many factors that contribute to the success of chemotherapy in dogs, and unfortunately, there is no one definitive answer for overall success rates. However, studies have shown that certain breeds of dogs respond better to chemo than others. For example, Golden Retrievers have been shown to have a 87% chance of surviving at least one round of chemotherapy, while Dachshunds only have a 50% chance.

In addition to breed, age also plays a role in how successful chemo can be for dogs. Younger dogs generally tolerate treatment better and have a higher survival rate than older dogs. One study showed that dogs under the age of 2 had a 79% chance of surviving at least one round of chemotherapy, while those over the age of 8 only had a 50% chance.

Finally, the type and stage of cancer also affects how successful chemotherapy can be in dogs. Certain types of cancers are more responsive to treatment than others, and cancers that are caught early are more treatable than those that are advanced. For example, lymphoma is often very responsive to chemo, with remission rates as high as 80-90%.

In contrast, metastatic cancer (cancer that has spread to other parts of the body) is much harder to treat and has much lower survival rates. Overall, there is no one answer for the success rate of dog chemotherapy. However, certain factors such as breed, age, and type/stage of cancer can play a role in how successful treatment can be.

What to Do If My Dog Becomes Lethargic After Chemo?

If your dog is lethargic after chemotherapy, it’s important to contact your veterinarian right away. While some fatigue is normal during treatment, excessive lethargy could be a sign of a serious complication. There are several potential causes for post-chemotherapy lethargy, including:

1. Infection: Chemo can weaken the immune system, making dogs more susceptible to infection. If your dog is showing signs of illness (e.g., fever, diarrhea, vomiting), contact your vet immediately.

2. Anemia: One of the most common side effects of chemotherapy is anemia (low red blood cell count).

This can cause fatigue and weakness. Your vet will monitor your dog’s blood counts during treatment and may prescribe medication to help boost red blood cells if necessary.

3. Dehydration: Chemotherapy drugs can cause nausea and vomiting, which can lead to dehydration.

Be sure to offer your dog plenty of fresh water and encourage him to drink often. If he’s not interested in drinking on his own, ask your vet about giving him subcutaneous fluids (under the skin) or IV fluids at the clinic.

4. Pain: Some dogs experience pain after chemo due to the side effects of treatment (e.g., mouth sores, digestive upset).

Find Out Whether Other Things That Can Kill Your Dog


Chemotherapy can be a difficult process for people, but it’s especially tough on dogs.

Dogs are much more sensitive to the chemicals used in chemotherapy than humans are, so they’re more likely to suffer from side effects like nausea and vomiting. Their bodies also don’t process medications as quickly as ours do, so drugs can stay in their systems for longer periods of time.

The good news is that there are ways you can help your dog feel better during treatment:

-Make sure your dog eats regularly and gets plenty of fluids. This will help them keep up their strength while they go through treatment.

-If your dog has lost their appetite, try giving them small meals throughout the day instead of one big meal at night—this way they won’t become too full too quickly and will hopefully feel like eating more later on in the day.

-Consider trying natural remedies to help your dog feel better during chemotherapy treatments such as ginger tea or ginger oil (you can give this directly to your dog or put some in their water bowl).
