Hello again, readers of The Bark! This is the second installment of the DIY physical dog exam. We are going to review the head today, continuing to move down the dog body over the series of posts.
To identify an illness or abnormal situation with your dog, you must first be able to recognize what is normal for your dog. You know your dog better than anyone else and you will have to decide when an abnormal situation warrants professional help. Sometimes the condition is so serious it leaves no doubt. Frequently, however, the changes are subtle, or happen over a longer period of time, making noticing a problem more difficult.
I will provide you with information on how to perform an at-home physical exam on your dog, helping to determine and establish what is normal for your pet. It is recommended that you occasionally perform this exam- while there is nothing wrong- so that you can begin to get used to what is normal. This practice will help allow for the early detection of changes in your dog’s health.
Examining For Infections
Start with examining your dog’s face and head for this dog physical exam: check the nose for discharge/boogers, check for eye infections, and how to check for ear infections. In the next part of our series, we will continue with the chest, and lastly, the abdomen. At the completion of this series of articles, you should have a complete home guide on how to perform a screening exam on your dog. Ready?!

CHECKING A DOG’S NOSE:
- Smooth, soft and clean; it is a misconception that a dry, warm nose means illness; sometimes a normal nose can appear slightly dry as well as warm to the touch; a healthy nose should feel like soft, supple leather; it is not necessarily always cool, wet and moist.
- Nasal discharge that is scant, clear or watery can be normal.
- A dog’s nose which is excessively dry and cracked is abnormal.
- If your dog has any colored nasal discharge; a green, yellow, or white discharge generally indicates a bacterial infection. You should report this information to your vet.
- Nasal bleeding is not typical.
EXAMINING A DOG’S EYES:
- Your dog’s eyes should be bright, moist, and clear.
- Centered between the eyelid.
- Pupils are equal in size.
- The whites of the dog’s eye should not appear colored and should have only a few visible blood vessels.
- Check your dog’s pupillary light reflex: Pupils should shrink equally when a bright light is shined into either eye and enlarge equally when the eyes are held closed or the room darkened.
- Dull, sunken eyes can indicate severe dehydration in dogs.
- Eyes that appear red, dry and “bloodshot” can indicate conditions such as uveitis, KCS (“dry eye”), severe dehydration, or other systemic illnesses.
- Thick discharge from eyes is abnormal. A little grey “eye booger” in the morning is normal, just like in us people, but be concerned if you notice any discharge with green or yellow color to it as this can be indicative of an eye infection.
- One or both eyes not centered: this can indicate a tumor or infection behind the eye, as well as other pathology.
- Pupils unequal in size: this can indicate head trauma, a possible tumor, other neurologic problems to name a few.
- Squinting or tearing of the eyes: this can indicate an ulcer or scratch on the cornea, which is the layer of cells covering the eye.
- Abnormal eye colors in dogs that indicate eye infections or problems are yellow (jaundice), or red (bloodshot); pay close attention to the color of the whites of your pet’s eyes.
- The appearance of blood in the eye (known as hyphema): this can indicate exposure to rat bait or other causes of your pet’s blood not being able to properly clot.
- Pupils fail to respond, or respond differently from one another, when a bright light is shined into either eye.
INSPECTING A DOG’S EARS:
Chronic ear problems are common in pets, and are often a result of allergies to inhaled pollen (like hay fever in people) that are then complicated by secondary infections with bacteria or yeast. Ear infections can be painful and head shaking can lead to an accumulation of blood in the floppy part of the ear, known as an aural hematoma. Symptoms of ear infections in dogs include head shaking, scratching at or rubbing the affected ear, discharge, bad odor, redness inside the ear, swelling of the ear canal, pain, itchiness, and crusts or scabs inside the ear or along the ear margin. If you suspect that your dog may be suffering from an ear infection reach out to your vet.
- Skin smooth and without wounds.
- Clean and dry.
- Almost odor-free.
- Typical carriage for breed.
- Pain-free when you massage them, especially at the base of the ear.
- Wounds, scabs, or any sign of rash is abnormal in dogs ears.
- Crust, moisture, or other discharge in ear canal can be a sign of an ear infection along with
- Any strong odor.
- Atypical carriage for breed; for example, a droopy ear in a breed with normally erect ears
- Painful or swollen ears.
CHECKING A DOG’S MOUTH:
- Teeth are clean and white.
- Gums are uniformly pink and moist to the touch (they should not feel dry or sticky).
- Capillary refill time (CRT): to assess, press on the gum tissue with your finger or thumb and then release quickly; the part you just pushed on will turn white, and you will then watch the color return to the gums; this is a crude assessment of how well the heart and circulatory system are working as well as hydration status of you pet; a normal CRT is 1 to 1.5 seconds for the color to return; this can be a difficult test to interpret sometimes (for example, if your pet has dark or pigmented gums), and should not be relied upon as definitive evidence that your pet is sick or healthy.
- Tartar accumulation around the base of the teeth.
- The gums are red: this can indicate severe dehydration, shock, heat stroke, or sepsis (severe infection in the body).
- Gums are bluish or purple: this indicates inadequate oxygen to the body; this can be noted with lung disease, heart disease, or any disease that impairs proper oxygen to the body.
- Gums are pale: this is due to lack of blood or shock and possible causes are internal bleeding (such as a mass on a spleen that suddenly ruptures and bleeds- very common in older dogs), trauma or shock (such as when a dog has been hit by a car), and immune mediated diseases.
- Gums that appear to have little bruises: this is known as petechiation and is generally seen with rat bait toxicity or other problems with the body’s ability to clot the blood
- Gums are inflamed, “spongy” looking, or sore in appearance.
- A sluggish CRT, or dry and sticky gums.
That completes the head! Please feel free to ask any questions and see you next week as we discuss and learn about the chest area, known as the thorax.
