Hypothyroidism
Whilst hypothyroidism can happen due to other issues, it’s more likely to be caused by autoimmune disease in dogs. Antibodies attack the cells of the thyroid gland, which creates difficulty in producing thyroid hormone. Some tell-tale symptoms of hypothyroidism include:
- Unexplained weight gain (and potentially, obesity)
- Thickened skin
- Unable to exercise as normal
- Increased sensitivity to cold temperatures
- Slowing down mentally/behaviourally
Lupus
Lupus is a canine autoimmune disease that attacks the body’s various organs and tissues, initiating widespread inflammation throughout the body. There are two types of lupus, and one is far more severe than the other. Here’s a quick breakdown of each:
Systemic lupus
Systemic lupus attacks the body’s vital structures, such as the nervous system, skin, organs, and blood, causing widespread inflammation throughout. This can prove fatal in dogs. Some signs of systemic lupus are:
- Swollen lymph nodes
- Seizures
- Fever
- Lethargy
- Anaemia
- Muscle pain/stiffness
- Skin issues such as sores, rashes, and bald patches (sores can also be inside the mouth)
- Lameness in varying limbs
Discoid lupus
Discoid lupus is the less severe of the two. It’s essentially the same process, just reserved for the skin itself. Symptoms of discoid lupus include:
- Itchiness/obsessive scratching
- Redness about the face, mouth, and nose
- Flaky or scaly skin
- Pale-coloured skin on the nose
- Skin sores
- Bacterial skin infections (due to excessive scratching)
Polyarthritis
Polyarthritis is a canine autoimmune disease in which immune cells mount their defences against the joints, causing inflammation and pain. This disease can also occur alongside other autoimmune diseases in dogs. Here are some common polyarthritis symptoms:
- Joint swelling
- Pain
- Swollen lymph nodes
- Fever
- Reluctance to move
- Crying out in pain when touched
- Shifting lameness (occurring in different legs at different times)
IBD
Inflammatory bowel disease, or IBD, happens when dogs’ immune cells attack the cells or bacteria in the gut, which leads to chronic inflammation and various digestive issues. Some symptoms of IBD in dogs include:
- Vomiting
- Diarrhoea/bloody stool
- Bloated stomach
- Gas
- Gurgling sounds coming from stomach area
- Abdominal discomfort
- Weight loss
- Poor coat condition
- Depressed mood
Addison’s disease
Addison’s disease, also known as hypoadrenocorticism, is an autoimmune condition in which the immune cells attack the adrenal glands. This inhibits the production of cortisol and aldosterone; two important hormones that are responsible for various essential functions. Here are a few common Addison’s disease symptoms:
- Vomiting
- Diarrhoea / bloody stool
- Weight loss
- Loss of appetite
- Hypoglycemia (low blood sugar)
- Irregular heart rate
- Decrease in body temperature
- Hair loss
- Skin darkening
- Lethargy
- Depressed mood
Immune-mediated hemolytic anaemia
Immune-mediated hemolytic anaemia occurs when the body’s immune system mistakenly targets and destroys its own red blood cells. This condition can pose a life-threatening risk, as red blood cells play a vital role in transporting oxygen throughout the bloodstream. Common symptoms of this autoimmune disorder include:
- Jaundice
- White or very pale gums
- Lethargy
- Depressed mood
- General weakness
- Loss of appetite
- Difficulty breathing
- Cold extremities
- Irregular heart rate
- Dizziness
Signs, symptoms, and potential impact
As highlighted above, each canine autoimmune disease will have their own set of symptoms. However, knowing the symptoms of all potential autoimmune diseases in dogs is not necessary. As you’re with your canine companion every day and know them better than anyone, you’ll likely notice when something’s not quite right or when they’re feeling unwell. Here are some general symptoms to be on the lookout for that may signal a potential autoimmune issue:
- Lethargy
- Weakness
- Loss of/decreased appetite
- Fever
- Skin issues such as rashes, sores, hair loss, or changes in pigment/composition
- Mobility issues
- Swelling/pain, especially around the joints
- Bleeding or bruising more easily than normal
- Pale or white gums
Whilst any of these symptoms on their own may not signal an autoimmune disease in your dog, they still warrant veterinary attention to be sure. Whether your dog has an autoimmune issue or something else going on, it’s better to be safe than sorry.
