Cough, Scratch, Woof: 10 Common Dog Symptoms You Should Never Ignore

Let’s face it: being a dog parent is basically having a toddler who never learns to talk, has a fur coat, and thinks the trash can is an all-you-can-eat buffet. They rely on us completely, which means we have to be part-time detectives.

We’ve all been there. You notice your pup skipping breakfast or letting out a weird cough, and the Googling begins. (Spoiler: Dr. Google always says it’s either nothing or a rare parasite from the Amazon). While we can’t diagnose via search bar, we can educate ourselves on the red flags.

To help you tell the difference between a “just a weird day” and a “vet visit, stat,” we’ve rounded up the 10 most common health issues in dogs and the specific symptoms that demand your attention.

1. Ear Infections: The Endless Head-Shaker

If your dog is shaking their head like they’re at a heavy metal concert, pay attention. Ear infections are incredibly common, especially in floppy-eared breeds like Cocker Spaniels and Labradors.

-Symptoms to watch for: Redness inside the ear, a foul smell (think corn chips mixed with yeast), constant scratching, or dark discharge.

The bottom line: A minor itch can quickly turn into a ruptured eardrum if ignored.

2. Dental Disease: The Silent Stinker

“Doggy breath” isn’t actually normal. If your dog’s kisses clear the room, it’s likely periodontal disease. By age three, most dogs have some form of dental issue.

Symptoms to watch for: Obviously bad breath, yellow-brown tartar on teeth, red or bleeding gums, drooling, or dropping food while eating.
The bottom line: Dental bacteria don’t just stay in the mouth; they can travel to the heart and kidneys.

3. Hot Spots (Acute Moist Dermatitis): The Itch That Spreads

These appear out of nowhere. One minute your dog is fine, the next they have a wet, oozing, angry-looking sore. These are “hot spots” - bacterial infections triggered by licking, allergies, or moisture trapped against the skin.

Symptoms to watch for: A rapidly spreading sore that is moist, hot to the touch, and painful. Your dog won’t leave it alone.
The bottom line: This requires a vet to clip the area and prescribe medication; home remedies usually make it worse.

4. Arthritis: The Slowing Down

If your once-energetic pup now thinks twice before jumping on the couch or seems “stiff” after a nap, it might be joint pain.

Symptoms to watch for: Lagging behind on walks, difficulty standing up, reluctance to climb stairs, or flinching when touched in a specific spot.
The bottom line: Dogs hide pain instinctively. If you notice a change in their mobility, they are likely hurting more than they show.

5. Kennel Cough: The Honking Goose

If your dog sounds like a goose that swallowed a squeaky toy, it’s likely Kennel Cough (Canine Infectious Respiratory Disease Complex). It’s highly contagious and common anywhere dogs gather (parks, daycares, groomers).

Symptoms to watch for: A persistent, forceful cough, often followed by a gagging sound or retching. They usually still act fine otherwise.
The bottom line: While often mild, it can turn into pneumonia in puppies or seniors. If the cough persists or your dog seems lethargic, get to the vet.

6. Gastroenteritis: The Tummy Trouble

Dogs eat things they shouldn’t. Sometimes it’s just a little grass, sometimes it’s your entire sock collection. Vomiting and diarrhea are common, but knowing when to worry is key.

Symptoms to watch for: Repeated vomiting (more than 2-3 times in a day), blood in vomit or stool (red or black, tarry stool), or a tucked belly (signs of abdominal pain).
The bottom line: Dehydration can happen fast. If your dog won’t keep water down, don’t wait until morning.

7. Allergies: The Endless Licking

Is your dog constantly licking their paws or rubbing their face on the carpet? Allergies (to food, pollen, or dust) are a top reason for vet visits in the US.

Symptoms to watch for: Red, stained fur on the feet (from saliva), chronic ear infections, hives, or recurrent skin infections.
The bottom line: Allergies are manageable, but constant scratching breaks the skin barrier, inviting secondary infections.

8. Bloat (GDV): The Time Bomb

This is the scariest one on the list because it’s a race against the clock. Gastric Dilatation-Volvulus (Bloat) usually affects large, deep-chested dogs like Great Danes or German Shepherds.

Symptoms to watch for: A distended (swollen) hard belly, unproductive retching (trying to throw up but nothing comes out), restlessness, pacing, and excessive drooling.
The bottom line: This is a life-threatening emergency. If you suspect bloat, go to the emergency vet immediately.

9. Urinary Tract Infections (UTIs): The Accidents in the House

If your perfectly house-trained dog suddenly starts having accidents, don’t get angry - get curious.

Symptoms to watch for: Straining to pee, passing only a few drops, frequent licking of the privates, or bloody urine.
The bottom line: UTIs are painful. They can also lead to bladder stones or blockages (especially in males), which are critical emergencies.

10. Conjunctivitis (Pink Eye): The Goopy Gaze

Red, swollen, or goopy eyes aren’t just an aesthetic issue; they signal irritation or infection.

Symptoms to watch for: Squinting, pawing at the face, green or yellow discharge, or visible cloudiness in the eye.
The bottom line: Eye issues can escalate to vision loss very quickly. Never use human eye drops on your dog.

The “WebMD” Trap and the Vet Visit Reality

Reading through this list might make you feel like a hypochondriac pet parent (welcome to the club!). But here is the golden rule of pet care: Recognize, don’t diagnose.

The symptoms above are your dog’s way of waving a white flag. But “redness” could be allergies or an autoimmune disease. “Limping” could be a sprain or bone cancer. There is no substitute for a physical exam, diagnostic tools, and the trained eye of a veterinarian. Skipping annual check-ups means missing the early warning signs that your dog can’t tell you about. Preventative care is always cheaper (and less stressful) than emergency treatment.

In addition to tracking your dog’s symptoms, don’t forget about the importance of having a first-aid kit at home. Read more about this here.

How to Be the Best Pet Parent on the Block

Staying on top of your dog’s health can feel like a part-time job. Between tracking when the symptoms started, remembering if they’ve had their heartworm medicine this month, and trying to understand why they are suddenly terrified of the mailman, it’s a lot.

This is where a little tech-savvy help comes in handy. Since we’re talking about being proactive about health, you might want to check out the Bobki app. Think of it as a command center for your furry friend’s well-being.

It helps you tackle the “prevention” side of the equation we discussed earlier. You can use the Task Calendar to track everything from deworming schedules and vet appointments to those monthly tick preventatives (so you never miss a dose!). And because understanding your dog’s mood is half the battle, the app includes a section on animal body language - helping you figure out if that lip lick means “I’m stressed” or “I want dinner.”

Because at the end of the day, knowing when somethings wrong - and keeping up with the routine stuff when everything is right - is the best gift you can give your four-legged best friend.
