Cancer Basics

What is cancer? How did my dog get it? Does this mean my dog is going to die? Get answers to these questions and find out what other questions you need to be asking.

The First Step

Give yourself time to experience the emotions and process the information. You don't have to have all the answers right now.

Getting More Information

Dr. Sue and Dr. Roark will talk about the importance of a comprehensive physical exam and get into detail about our two earliest diagnostic steps: fine needle aspirates and biopsies.

Imaging & Cancer

What is the difference between an x-ray, ultrasound, CT scan, and MRI? When would my dog require one versus the other? What can I expect from the process and what will these tests tell me? We'll cover it all in this module.

What You Need to Know About Specialists

When it comes to specialists, don't be intimidated. Referral to an oncologist, radiologist, surgeon, or internist doesn't have to mean you're committing to anything. Instead, take the opportunity to understand more about your dog's condition.

Treating Cancer With Surgery

There are 3 methods of treating cancer: surgery, radiation, and chemotherapy. Here, we'll talk all about surgery - when it is indicated, how it will help, what it will tell us, what it involves, and what to expect before, during, and after the procedure.

Treating Cancer With Radiation

Dr. Sue and Dr. Roark will cover the 3 types of radiation, how they work, and when we use them. They'll even prepare you for what to expect in regards to time, travel, cost, and side effects.

Treating Cancer With Chemo

Forget everything you think you know about chemotherapy. Did you know that 80% of dogs have no side effects whatsoever? Here, we'll cover the types of chemotherapy, when and how they are used, and the associated risks. We'll also give you the heads up on time, cost, and side effects so you know what to expect.

Specific Cancers: Lymphoma

Let's talk about Lymphoma: what it is, how we treat it, and what you can expect if you've just found out your dog has it.

Specific Cancers: Osteosarcoma

What is an osteosarcoma? Here, we'll talk about how we find bone cancers, the (radical) treatment options, and the prognosis.

Common Dog Cancers: Hemangiosarcoma

This type of cancer is commonly hiding out of site and can catch us by surprise. Dr. Sue talks about what she refers to as her least favorite type of cancer and why it can be especially challenging.

Common Dog Cancers Mast Cell Tumors

Dr. Sue tells us about the importance of early detection and how every mast cell tumor is incredibly unique.

Common Dog Cancers: Mammary Tumors

You've heard about breast cancer in humans, but now let's talk about it in dogs. 50% of canine mammary tumors are malignant and early detection is key. Let's cover the treatment plan and prognosis for this type of cancer.

Supportive Care

What if I decide not to do surgery, radiation, or chemotherapy? That's ok. Sometimes, the best course of action for you and your dog is simply to provide supportive care. Dr. Sue and Dr. Roark have some important things you need to hear about quality of life and why it's so much more important than quantity when it comes to your dog.

Tips for Keeping Your Dog Feeling Well

Dogs can't talk, but they can tell us a lot through their behavior. It's important that you learn how to monitor your dog at home, know how to recognize things like nausea, pain, and dehydration, and are made aware of the many options that are available for treatment.

End of Life Planning 

Humane euthanasia is a wonderful option we have available for our pets so that they do not have to suffer. There are a lot of choices and decisions involved at the end of your dog's life - let us help you sort out the details ahead of time so that you are as prepared as possible when the time comes.
