    10 Symptoms Of Cancer In Dogs To Look Out For

    by Health & Wellness / 3 min read

    Symptoms Of Cancer In Dogs

    Cancer is a risk for dogs, as much as it is for humans. And as our canine companions get older, their bodies are far more susceptible to health risks and diseases. According to the American Veterinary Medical Association, around half of dogs over the age of 10 in the United States will develop cancer. That's a huge amount. 

    Cancer is an uncontrolled cell growth in or on the body, which can either be localized, or it spreads by attaching to neighboring tissues. When found early, it can be removed with a surgical procedure, but the later it’s found, the more dangerous it can become for your dog. Cancer can spread around a dog’s body faster than it can a human’s body, resulting in approximately 50% of deaths in dogs is caused by cancer.

    However, there are ways to spot cancer from early on, and there are steps you can take to reduce the chance of your beloved dog from developing this deadly disease. As soon as you notice any of the symptoms, take your dog to a veterinarian for a diagnosis to give them the best chance of survival.

    Cancer In Dogs: Symptoms And Signs

    Symptoms Of Cancer In Dogs: Abnormal Swelling Or Bumps Under The Skin

    It’s important to check your dog’s skin regularly for bumps and lumps, which you can do just by stroking them. Don’t forget to check around the face and behind the ears. Even if you only spot a small lump, if it is cancerous, the lump may grow or spread. If the swelling or bump bleeds or leeks, seek medical attention immediately.

    Symptoms Of Cancer In Dogs: Sores That Don't Heal

    If your dog has sores or wounds that aren’t healing properly, this could be a sign of a bigger medical problem such as cancer. If you notice that a wound is taking longer than normal to heal, ask your vet to check why this could be happening.

    Symptoms Of Cancer In Dogs: Loss Of Appetite

    A change in appetite could be down to a variety of different health problems, from the serious to the silly. But this behavioral change is your dog’s way of showing that something isn’t quite right. Listen to them, because it could save their life.

    Symptoms Of Cancer In Dogs: Weight Loss

    Dogs tend to maintain their weight naturally if their exercise and feeding habits don’t change. So, if you notice that your dog is losing weight, without a change in diet, then that instantaneous loss is likely caused by a deeper health problem.

    Symptoms Of Cancer In Dogs: Offensive Odor

    Although “dog breath” is common and often very unpleasant, you may recognize a smell worse than normal. If you do, it could be a sign of oral or throat cancer. Or, you may notice a bad smell coming from their nose or rectal area, which is a sign that there could be a tumor there.

    Symptoms Of Cancer In Dogs: Vomiting & Diarrhea

    Regular vomiting is a sure sign that your dog is suffering from a health problem, and cancer could be it. Diarrhea is also a sign that their stomach is suffering. Also, check for visible bloating and distension of their abdomen. If you notice that their stomach is playing up, along with any other of these symptoms, take them to the vet.

    Symptoms Of Cancer In Dogs: Difficulty Defacating

    If your dog’s poo is thin and ribbon-like, their guts might have an issue. And if your dog is male and struggling to pass stools, there’s a possibility it’s caused by prostate cancer. Take note of how their stools look over a couple of days, and if you suspect it’s not just that they ate something dodgy, get medical help.

    Can I Stop My Dog Developing Cancer?

    We can’t tell you that anything will prevent cancer, because there is not a straight forward cause of the disease. It can affect different parts of the body at any age, although with older age, the chances do increase.

    But, we have come up with some simple tips that could reduce the chances of your furry friend developing cancer. They will help your dog stay healthy, and hopefully keep them away from nasty illnesses, but there is no guarantee that they can prevent cancer or any other disease from occurring.

    Keep Checking

    The only way to know for sure whether your dog is well is to keep checking. Feel their skin, watch their behavior, smell for odors, and take them to their annual health checks at the veterinarian! If you are concerned that your pup is at risk of cancer, ask for more regular health checks. Early diagnosis is the key to stopping cancer from taking your dog’s life.

    Healthy Diet And Good Weight

    Dogs that are overweight are far more likely to develop health problems that affect their heart, kidneys, lungs, and their joints, which can cause them tremendous pain. But, it can also increase the chance of cancer.

    It’s also essential to give your dog all the vitamins they need. Feed them a healthy diet – yes, that can include fruit and vegetables! Although, be careful, because certain foods can be fatal for dogs.

    If you worry that your pal isn’t getting all the nutrients he needs, and you don’t know how to feed them to him (or perhaps they’re a fussy eater), you can give it to them in supplement form! Look to a reputable pet brand who make multivitamin supplements for dogs, to help boost their overall health and vitality.

    Good Oral Hygiene

    Dental hygiene in dogs is often overlooked, but it's actually incredibly important for their overall health! Dogs do a lot with their mouths, which means foreign objects and bacteria can get into their systems, causing further health problems.

    The more direct risk is oral cancer. Cleanliness can’t necessarily keep your dog’s mouth 100% safe from mouth cancer, but the more often you brush it, the more aware you are of changes such as tumors appearing. Keep an eye on their gums, lips, and pallet.

    Spaying Or Neutering

    Spaying a female pet will eliminate the possibility of uterine or ovarian cancer, and decrease the likelihood of breast cancer. Neutering male pets will reduce the chance of getting prostate cancer. It’s also said that spaying and neutering give your dog a higher chance for a longer and healthier life!

If you find that your dog has been diagnosed with cancer, it’s up to you and your vet to decide what’s best for your dog.
