Chemotherapy
Chemotherapy uses specialised medications to slow or stop the growth of cancer cells. It may be used to shrink tumours, control the spread of disease, or, in some cases, achieve remission. In veterinary medicine, the aim is not only to treat the cancer but also to maintain your pet’s comfort and quality of life throughout.
At PetPeople Vets, we know that a cancer diagnosis can feel overwhelming. We are here to guide you gently through each step with clear information, compassionate support, and a treatment plan tailored to your pet’s individual needs.
Why chemotherapy matters
Chemotherapy can offer pets valuable extra time with good quality of life. Unlike human oncology, where treatments can be aggressive, veterinary chemotherapy is usually much gentler, and more focused on maintaining the pet’s comfort and wellbeing. Most pets experience only mild, manageable side effects and are able to enjoy their normal routines at home.
With a combination of skilled clinicians, modern medications, and close monitoring, we are well placed to provide safe, thoughtful chemotherapy options for dogs and cats with cancer.
More about chemotherapy
How chemotherapy works
Chemotherapy drugs target rapidly dividing cells - rapid division is characteristic of many cancers. Different protocols are used depending on the type of cancer, how far it has progressed, and whether the goal is cure, remission, or control.
Treatment may involve:
Intravenous injections
Oral medication
Combination protocols using more than one drug
Supportive treatments such as anti-nausea medication or immune support
Your vet will explain the recommended plan and what outcomes you can expect.
Safety and monitoring
Your pet will receive regular check-ups, blood tests, and examinations to ensure treatment remains safe and effective. Our nurses and vets are trained in handling chemotherapy drugs with care, and you will be given clear guidance on any medication to be administered at home.
Conditions commonly treated with chemotherapy
Lymphoma
Mast cell tumours
Soft tissue sarcomas
Certain bone cancers
Leukaemia
Other metastatic cancers
Chemotherapy may be used alone or alongside surgery, immunotherapy, or radiotherapy (via referral to a specialist centre where required).
Quality of life first
Veterinary oncology prioritises comfort. If at any point chemotherapy is no longer the kindest option, we will discuss alternatives and supportive care to keep your pet comfortable. You are never alone in making these decisions.
Frequently asked questions about chemotherapy
-
Depending on the medication, chemotherapy may be given by injection at the practice or as oral tablets taken at home. Your vet will advise you on the exact protocol and schedule.
-
Treatment frequency varies but is often weekly to begin with, then spaced out over time. Many protocols run for several months. Each plan is tailored to your pet and the type of cancer being treated.
-
Most pets tolerate chemotherapy well. Possible side effects include mild nausea, diarrhoea, reduced appetite, or temporary tiredness. Hair loss is uncommon in dogs and cats except for certain breeds. Serious side effects are rare but monitored closely.
-
No. The injections themselves are quick, and the medication does not cause pain. We ensure your pet is as comfortable and relaxed as possible throughout their visits.

If your pet receives oral chemotherapy, you’ll be given clear instructions on safe handling, storage, dosing, and what to do if a dose is missed. Wearing gloves and washing hands afterwards is typically advised.
