Chemo Side Effects In Dogs

What Are The Side Effects Of Chemotherapy In Dogs

Chemotherapy Cancer Treatments & Side Effects : Side Effects of Chemotherapy on Dogs

Side effects for dogs are milder and generally last for a shorter period of time than for humans receiving chemotherapy because dogs are given less-aggressive treatment, Intile said. In fact, 75 to 80 percent of dogs have no side effects, she said. When present, typical side effects include loss of appetite, vomiting and diarrhea.

Less than five percent will suffer those effects more severely and will need to be brought into the vet to receive fluids, she said. There may be little windows of time to restrict activity, maybe days three to five . But we dont want you to put your dog in a bubble. Our goal is for your pet to have a totally normal lifestyle, she said.

If symptoms do not resolve in a day or two, call your veterinarian.

What causes side effects is the indiscriminate nature of chemotherapy drugs, which kill both normal and abnormal cells in an innocent bystander effect, Barber said. Such indiscriminate destruction can affect your dogs bone marrow, which produces blood cells. The most common problem that we see is low white blood cell counts. The white blood cells are the first line of defense against infection, and a low white blood cell count can put dogs at risk for infections, she said.

How Long Are Pets Typically Given Chemotherapy

The number of treatments given depends on the type of cancer, the chemotherapy protocol and the pets responsiveness to treatment. There are various protocols available, and the success and prognosis associated with each protocol differ. In a few cases, long-term maintenance chemotherapy may be recommended.

How Long Do Dogs Live After Chemotherapy

The average survival with chemo treatments is typically 10-12 months, although some dogs have been known to live for years. This greatly depends on the type and stage of cancer and how aggressive it is. Some tumors respond better to chemo than others.

At some point, however, most dogs with cancer will relapse. This is where maintenance therapy comes in it helps keep the cancer under control and extends survival time after initial treatments are completed.

Mild Canine Lymphoma Chemotherapy Side Effects

The types of mild side effects that Canine Lymphoma patients can expect as a result of their chemotherapy care include:

  • Loss of Appetite
  • Some fever because their white count is low and theyve got an infection

But again, these side effects are rare and most of these side effects may last only for a few days.

Chemotherapy: Managing Side Effects And Safe Handling

Canine Lymphoma

Chemotherapy is a common treatment modality in many veterinary cancer patients in addition to surgery and radiation therapy. Cytotoxic drugs can lead to complete remissions for some disseminated cancers , be effective in decreasing tumor size, and may prolong life in many other types of metastatic cancers, such as osteosarcoma. The choice of specific therapies depends on tumor type , histologic grade of the tumor , stage of disease , and the patients tolerance for the side effects of the various treatments. Most of the chemotherapy protocols designed for veterinary patients have a < 5% incidence of severe, life-threatening complications . Most veterinary chemotherapy patients enjoy a good quality of life while on therapy. This article will discuss some of the side effects associated with chemotherapy in veterinary patients and how to effectively treat them. In addition, an overview of chemotherapy safety for both patient and veterinary staff will be discussed.

Simply put, chemotherapy kills rapidly dividing cells. Unfortunately chemotherapy drugs do not differentiate between killing tumor cells and normal cells. Thus, the general side effects of chemotherapy include bone marrow suppression, gastrointestinal problems , and alopecia . However, in addition to the general side effects seen, specific side effects can result from certain drugs, for example, doxorubicin and cisplatin .

The Oncology Roller Coaster

In most cases, once your dog has been diagnosed with cancer, hes referred to an oncologist.

From this point on, for you as the owner its as if any decision-making ability you might have had has been removed.

The oncologist now calls the shots. Your dog is on the medico-veterinary roller coaster the medical merry-go-round.

And in far too many instances, that ride is one of unimaginable horror.

You watch on as your beloved family member is taken from a life filled with innocence and joy to one of relentless torture.

Under the skilled guidance of the cancer professional, your helpless dog is poisoned by chemotherapy and/or burnt by radiotherapy until death ensues.

A slow death, where your dog with his immune system destroyed and all will to live taken away by nausea and pain becomes a walking skeleton. Until finally, death is the only option the inevitable outcome.

More Significant Canine Lymphoma Chemotherapy Side Effects

While more significant side effects are possible, only a very small percentage of dogs require hospitalization for the side effects of there conventional chemotherapy care.

The number of patients that Dr. Freeman has to hospitalize each year, are just a handful, out of maybe 500 to 1,000 patients that she treats each year.

In addition, in cases where side effects are likely, your vet may be able to adjust the dosages or provide certain medicines that can counteract the side effects to make the process easier for your dog.

Always be sure to let your vet know if your dog is undergoing any side effects from any Canine Lymphoma chemotherapy treatment, so he or she can make adjustments or prescribe other methods to make your dog more comfortable through the process.

If a dog is treated with Chemotherapy on Monday, then the general cycle is for them to feel fine on Monday and Tuesday, and then they start experience some weakness on Wednesday and Thursday, and then theyre fine again until theyre ready for their next chemotherapy treatment.

For some of the chemotherapy drugs used in conventional canine lymphoma care, the risk of side effects is small, so the vet may not worry about it too much. But for certain chemotherapy treatments where the risk of side effects are more significant, vets may prescribe anti-nausea or anti-diarrhea drugs to counteract those potential side effects.

Gastrointestinal Effects From Chemotherapy

Chemotherapy in Dogs

Side effects to the gastrointestinal tract are among the most common of those occurring as a result of chemotherapy. These effects typically result from the basic breaking down of the inner lining of the intestines. The most common gastrointestinal effects that occur in dogs include:

  • Black, tarry stools

The severity of these conditions can vary tremendously from case to case, and it’s difficult to predict how chemotherapy will affect your pet in particular. While most of these gastrointestinal effects are relatively mild and tend to go away on their own as the treatment continues, they can be moderate or even very severe. It’s important to work with your vet to ensure that your pet does not require additional treatment some dogs will require hospitalization and fluid therapy in order to treat massive diarrhea.

What Are The Side Effects Of Chemotherapy

Chemotherapy aims to disrupt cancer cell division by targeting rapidly dividing cells. It will not know the difference between rapidly dividing cancer cells and normal tissues. Thus, side effects may occur to the normal, rapidly dividing bone marrow, hair follicles and gastrointestinal tract.

The easiest way to remember chemotherapy side effects is by remembering BAGS.

B = Bone marrow suppression

A = Alopecia

G = Gastrointestinal side effects

S = Specific/special side effects related to a particular drug. For example, doxorubicin can cause cumulative cardiotoxicity.

What Are The Chances Of A Dog Surviving Cancer

A dogs chances of surviving cancer depend on various factors, including the aggressiveness of cancer and when treatment begins. The chances of going through cancer in dogs treatment and surviving are higher for patients with an early-stage cancer diagnosis.

As we mentioned above, good treatment and quality of life are key things that a pet owner can give their dog with cancer. For healthy dogs, dog owners should do their best to keep their dogs in optimal health.

Also, many dog owners wonder how to prevent cancer in dogs. Sadly, there is no one thing you can do to shield your dog from developing cancer. But there are ways of minimizing the risk. Some of these include a healthy diet, physical exercise, proper and regular veterinary checkups.

What Are Mast Cell Tumors

Fluorouracil 5 Cream Pictures Photos

The body produces mast cells as an inflammatory and histamine response. This is a part of normal immune function.

Mast cell tumors happen mostly on the skin but sometimes in the internal organs.

Mast cells are part of your dogs immune defense system. They live within the tissues that contact the outside world. This includes the skin, respiratory tract and intestinal tract.

The mast cells main job is to defend against parasites.

They have unique granules within their cells that act like small bombs. The cells release those granules into the tissues to destroy the invader. This release also signals other body defenses to assist as needed.

Our dogs are living in a much cleaner world than their ancestors. They dont run into parasites as often as they once used to.

So the mast cells are looking for a job.

This means they sometimes react to other environmental triggers that have a similar shape or size to parasitic antigens like pollens and proteins. This is when you might see signs that look like allergies local skin redness, itching, swelling, sneezing or watery eyes.

As I mentioned, MCTs stem from the bodys inflammatory and histamine responses. MCTs have an affinity for the blood, digestive system, skin, spleen and liver.

Dogs who might be prone to MCTs are dogs who often suffer from:

Many dogs who suffer from seasonal allergies deal with the release of histamine. This reaction happens continually when a dog has an MCT.

Is The Experience For Pets The Same As For People Receiving Chemotherapy

NO! This fact needs to be made clear. In people the goal of treatment is often cure, while for animals it is usually management to provide an excellent quality of life, for as long as possible. People receive chemotherapy at higher doses, more frequently and with lower WBC counts than do dogs and cats. This level of aggressiveness places people at significantly higher risk for the development of side effects. This is a level of risk not taken in veterinary oncology.

General Cancer Treatment Considerations

Keep a few things in when treating your dog for cancer:

  • Cancer treatment can cost thousands of dollars. Consider your budget when discussing cancer treatment options with your veterinarian.
  • Monitor your dog closely and alert your veterinarian if your dog’s symptoms have worsened or their quality of life has decreased.

Be realistic about treatment success. Your dog may succumb to cancer despite receiving the best possible treatment. Accepting this reality can better prepare you for your dog’s cancer treatment journey and potential outcomes.

How Long Do Dogs Live With Cancer

Chemotherapy for Dogs Demystified | Dr. Sue Ettinger Deep Dive

The time a dog lives with cancer varies widely. The lifespan of a dog with cancer depends on many factors, including the form of cancer, stage of cancer, available treatment options, and a dogs overall health.

Dogs whose cancer is caught and treated early tend to live longer. Those whose cancer is caught in the later stages may not live as long because the cancer is advanced and treatment may not be effective.

The time your dog has with cancer is very individual. Early detection and high-quality cancer in dogs treatment are crucial to giving your dog extending your dogs lifespan with cancer.

Dog Has A Growing Lump On Abdomen

Dear Ted, Firstly congratulations on a truly wonderful and inspirational site. My dog has a growing lump on her abdomen. It was biopsied a year ago and found to be a fibromatous type mass. However I am a doctor and alternative practitioner and fibromatous masses may or may not grow and harden as the rate and to the degree that this has. Please send me suggested list of doses/weight for apple cider vinegar, H2O2 etc on your possible cancer list unless you have any other suggestions. The same dog, age 10 cross cocker/border collie has bladder incontinence and also very occasional psoriatic type small patches mostly on her back nearer her bum. Her blood test last year suggested a possible thyroid condition, though not definite or typical. She eats well and is boisterous, alert, so personality fab. Well thatâs about it. Many thanks

PS I am happy to give your suggestions a trial as all these remedies under cancer also work well for humans however i am unaware of dosages for animals. Once I know the dosages I will gladly send you the feedback to publish. Thanks again

The large lumps of fibrous mass can also be applied three times a day of borax in 1% H2O2. The penetrant effect can kill the lumps in event the causal nature of the large agressive lumps is a viral one.

What Are The Most Common Side Effects Of Chemotherapy

Chemotherapy impacts rapidly dividing cells. The susceptible cell populations are cancer cells, cells of the GI tract, the bone marrow, hair follicles and reproductive cells. In treatment, we are happy to be rid of the cancer cells, as that is the ultimate goal of therapy. GI side effects are the most commonly noted chemotherapy side effects. We can see vomiting, diarrhea, loss of appetite or some combination develop. Bone suppression can result in a transient decrease in WBC numbers. Usually the neutrophil count will not drop low enough to be of any clinical concern. In 5-8% of cases, moderate to severe neutropenia may develop which will require intervention and treatment and will result in a need to lower the dose of certain chemotherapy drugs moving forward with future treatments. Hair loss in cats is rare, though the loss of whiskers is commonly associated with doxorubicin treatment. Hair loss in dogs is most commonly seen in dogs with continuously growing coats. Most dogs will not lose all of their hair, many will lose their course overcoat and develop a fine puppy coat. Smaller dogs and those with lighter coloured hair coats appear to be at highest risk for hair loss. Cats whiskers and dogs hair will grow back after chemotherapy has finished. Usually, because of prior spaying or neutering, reproductive cells are not an issue, though intact animals should not be bred.
