CARING FOR YOUR PET DURING CHEMOTHERAPY

When your vet diagnoses your pet with cancer, one of the primary treatments they recommend is chemotherapy. Fortunately, unlike humans undergoing chemotherapy, most cats and dogs experience little to no symptoms. When it comes to hair loss, apart from Poodles, Old English Sheepdogs, and Bichon Frises, most dogs keep their hair during chemotherapy. For some pets, however, chemotherapy can be harsh. They can experience vomiting, bloody and non-bloody diarrhea, poor appetite, and low energy levels.

Chemotherapy will weaken your pet’s immune system. Ensure to keep your pets inside during treatment and minimize exposure to other pets and animals. Minimal exposure will reduce their chances of contracting a secondary infection resulting from bacteria or viruses. Also, protect your pet as best you can from injuries, such as scratches, that can introduce unwanted germs into your pet’s system leading to illness. Call your vet immediately if any swelling, redness, or rashes arise around scratches or bites your pet has acquired.

During your pet’s chemotherapy, you want to provide care to reduce their pain and discomfort from these side effects. You can ensure your pet is adequately medicated, has a comfortable and quiet place to rest, stays hydrated, and eats nutritious foods. The most comforting thing you can offer your pet is your presence. Ideally, your pet’s daily routine should not be interrupted, as routine can give a sense of comfort and stability for both you and your pet.
If your pet is suffering side effects that require a visit to the hospital, it is likely their chemotherapy requires an adjustment. When you are not sure what you can do for your pet during their treatment, speak to your vet.

When your pet is undergoing chemotherapy, you must also protect yourself. Your pet’s feces and urine can potentially contain the breakdown of chemotherapy chemicals. Therefore, specialists recommend you wear protective latex gloves when touching your pet’s waste 24 to 48 hours after their treatment administration and wear gloves to handle any chemotherapy pills.

One of the best ways to care for your pet during treatment is to ensure they feel loved and comfortable throughout their illness. As scary and ambiguous as cancer treatments can be, your love for them is one thing they can always rely on.
