Dog Skin Cancer: Types, Symptoms, and Treatment

I have never had to deal with dog skin cancer as a pooch owner. However, having a few breeds statistically more prone to the disease meant that I had to study up so I knew how to pick out warning signs and what to do to protect my best buddy. Unfortunately, skin cancer in dogs is all too common and is in fact one of the leading cancerous causes of death.

The good news is that when caught early, you could start appropriate treatment and give your dog a few more years on earth. For that, you need to know not just what you are dealing with but also what to look forward to.

Skin cancer symptoms in dogs manifest differently depending on the specific type. This also determines the treatment cause of action and overall survival rate. Some of the main types of skin cancer in dogs include:

  1.   Mast Cell Tumors
  2.   Malignant Melanoma
  3.   Squamous Cell Carcinoma
  4.   Fibrosarcomas
  5.   Lymphomas
  6.   Hair follicle tumors
  7.   Histiocytic Cell Tumors

There is a lot to cover with dog skin cancer from signs to look out to and treatment options to how to actually lower the risks of your dog developing the disease. However, let us first take a closer look at the 5 main tumors and what exactly they mean for your furry bestie. 

What Are The Types Of Dog Skin Cancer?

Skin cancer on dogs looks very different depending on the type of the tumor and the stage. For perspective, here is a list of 5 of the most common types of skin cancer in dogs, their appearances, and their potential outcomes.

Mast cell tumors

Mast cell tumors form the most common type of skin cancer in dogs. Despite being so common, they are often misdiagnosed as allergic reactions. This is because they produce histamine which triggers non-specific irritation.

Squamous cell carcinoma

Squamous cell tumors on the other hand are the most easily and most commonly diagnosed when it comes to dog skin cancer. They occur mainly in older dogs and are associated with sun exposure. They present as raised lumps or areas of inflammation that are painful when touched.

Malignant melanoma

These tumors are relatively easy to diagnose when picked early and can be identified through their signature darker appearance compared to the rest of the skin. It could be a flat wart-like lesion or a raised growth and they mainly appear on exposed surfaces like lips, the nose, nailbed, and paw pads. It is one of the most problematic types of skin cancer as it spreads quickly in dogs to other vital systems.

Spindle cell tumors

These are known as Fibrosarcomas and feature invasive growth of fibrous tissue in the skin. They occur mainly on limbs and are unique in that they can attack dogs at pretty much any age. The biggest issue with spindle cell tumors is that they are likely to recur even after successful treatment.

Lymphomas

Strictly speaking, lymphomas are not technically skin tissue tumors but instead cancer of blood cells. Manifestation on the skin through painful bumps is usually a sign of final stages of lymphomas in dogs involving widespread and often fatal metastasis.

What Are The Signs Of Cancer In A Dog?

Most forms of skin cancer can be a little tricky to identify. More often than not this is as a result of confusion between dog skin cancer and other skin conditions like warts and skin tags. To help you out, here are some of the most obvious signs of dog skin cancer that you could use to tell if your dog is suffering.

Unusual lesions on the skin

These take different forms including wart-like lesions, open sores, raised bumps, skin hot spots and even protruding growths. As earlier mentioned, different tumors present differently depending on their specific pathological basis.

Rapidly growing skin growths and ulcers

One of the best ways to differentiate between cancerous lesions and those from benign growths or infections is the time they take to grow.

Unlike infections, these lesions will appear slowly and progress over a few months. However, their growth is noticeably faster and more seemingly exponential than that of benign tumors.

Painful lesion

These skin cancers also more often than not tend to be painful. This is because unlike the benign ones, they are invasive and tend to affect nerves making them particularly tender especially when touched which is the best way to know your dog is in pain from cancer.

Intense itchiness

This is the case mainly with mast cell tumors that tend to produce histamine that causes irritation and itchiness. However, it could also be due to the other tumors in cases of ulceration and infection.

Non-specific symptoms

In addition to the specific signs and symptoms on the skin, you may also notice some vague changes in the pooch’s behavior. This is often a symptom that the canine skin cancer has spread and is affecting the functioning of other systems. The signs here include weight loss, fatigue, whining, and loss of appetite.

What Can You Do For A Dog With Skin Cancer?

The answer to whether or not skin cancer can be cured depends on several factors. These determine not only the rate of progression and intensity of the cancer but also the treatment options and most likely outcomes. Let us take a look at 3 of the most influential factors that will determine whether or not your dog’s skin cancer can actually be cured.

Type of skin cancer

This determines things like the level of invasiveness of the tumor and the response to treatment. Some tumors like mast cell and squamous cell cancers are easily removed through surgical means with little to no need for adjunct therapy like chemo or radiation.

Other tumors like lymphomas and melanomas, on the other hand, need very powerful combinations of all 3 therapies if your dog is to have any chances at surviving.

Stage of the cancer at the time of discovery

With all types of malignancies including skin cancer, it goes without saying that cancers that are detected early are easy to treat. This is because the chances that it has spread beyond the skin are much lower.

However, with subtle cancers like mast cell tumors or aggressive ones like melanoma, the discoveries are often made very late and therefore reduce overall cure rates. This is one of the main reasons why dogs die from skin cancer.

Dog’s age and overall health status

Younger and healthier dogs typically bounce back faster and respond better to different cancer treatments than their older counterparts. This is because they need to be strong for the often brutal therapies.

Can Dog Skin Cancer Be Cured?

When it comes to what you can actually do for your dog with skin cancer, there are 4 main options. What you choose will obviously depend on the type of cancer and the stage. The price also matters because it can be very expensive to treat cancer in a dog with costs of up to $9000 or more. Let’s dive right into your options.

Surgical removal of tumors

When it comes to non-aggressive tumors and those that are caught early, this is without a doubt the best option. Surgical treatment is also the most affordable option and will set you back only $300 to $1000 to remove a tumor from a dog depending on the size and number.

Radiotherapy

Radiotherapy is used to deal with harsher and more invasive tumors. While not effective on its own, it has been shown to increase the overall effectiveness of surgical and drug therapies for skin cancer.

Chemotherapy

This is the most effective method of dealing with more advanced stages of skin cancer especially where metastasis is suspected. Dogs typically live for 10 to 12 months after chemotherapy but survival rates of 2 years or more are not completely unheard of. It is therefore safe to say that chemo is worth giving a try when dealing with dog skin cancer.

Euthanasia

Finally, sometimes, the best thing to do for your dog with skin cancer is to put them down.

Remember that skin cancer is painful for dogs and so are the three treatments highlighted above. If your dog has lived a good life and the cancer has progressed too far, this may be the most humane course of action.

How To Prevent Dog Skin Cancer

There is no specific cause of skin cancer in dogs that if avoided will give full immunity from ever developing the tumors. However, there is a lot you could do to minimize the risk by avoiding factors that make your dog more likely to suffer the horrible disease. Below are a few things you could do to help prevent dog skin cancer.

Go organic with your meals

A lot of dog food options out there are just overflowing with artificial additives from preservatives to flavor enhancers. A lot of these chemicals have been linked to cancers including skin tumors. We recommend you go the all-natural route with options like Ollie.

Protect your pooch from the sun

Excessive sun exposure has been linked to different skin cancers including melanomas and squamous cell tumors. To protect your furry bestie, take measures to protect them from this through things like providing shaded outdoor play areas, investing in dog clothes, and of course applying dog sunscreen.

With the latter, try out the SIT STAY FOREVER Dog Sunscreen. It is free from toxic chemicals like zinc, titanium, benzones, and many others. It is also enriched with natural oils including coconut oil, olive oil, and shea butter to further improve skin health.

Neutering

Some skin cancers like malignant melanomas have been shown to be sensitive to sex hormones like estrogen. Neutering could therefore come in handy when it comes to their prevention as well as reducing the risk of other hormone-dependent cancers like ovarian and breast cancer in dogs.

Make vet visits regular

This might not necessarily prevent the tumors but it does increase your chances of successful treatment with early detection. In addition to regular visits, do not ignore any skin lesions even those that look like harmless skin tags or warts. It is better to get them checked out professionally just to be safe.

Is Dog Skin Cancer Contagious To Humans? Dog skin cancer is not contagious to human beings at all.

However, tumors caused by papilloma viruses may be contagious to other dogs in which case it is the virus that is spread and not the tumor itself.
