Dogs are family, no question. Whether they’re curling up beside you on the couch or jumping out of a truck to search disaster rubble, dogs show up for us in ways that few other animals, or humans, can.
But behind those wagging tails and loyal eyes, there’s more going on than many owners realize, especially when it comes to health.
The truth is, not all dogs face the same risks. And as more people adopt breeds designed for work -search and rescue, herding, service tasks – the line between “pet” and “working partner” gets blurry. That’s where health issues, for both dogs and humans, can slip under the radar.
Let’s break down what’s actually at stake, what owners may be missing, and what smart prevention looks like in 2025.
Zoonotic Diseases You Might Be Bringing Home
Dogs, no matter their job description, can carry diseases that pass to humans. These are called zoonotic diseases, and while not every pup is a ticking time bomb, the risk is very real – especially if hygiene or vet care falls short.
Here’s a look at some of the most common offenders:
| Disease | Cause | Human Symptoms | How It Spreads | Notes |
| Rabies | Virus | Fever, hallucinations, paralysis | Bite from infected dog or wild animal | Rare in vaccinated dogs, but fatal if untreated |
| Campylobacteriosis | Bacteria | Diarrhea, fever, cramps | Contact with feces, esp. from puppies | Found in nearly 50% of dogs |
| Salmonellosis | Bacteria | GI issues | Feces, contaminated food | Dogs often show no symptoms |
| Leptospirosis | Bacteria | Vomiting, kidney damage | Contact with urine or water | More common in rural/wet areas |
| Toxocariasis | Roundworms | Eye damage (rare), often asymptomatic | Soil with eggs; hand-to-mouth in kids | ~14% of Americans exposed |
| Hookworms | Parasite | Rash, rare GI issues | Barefoot contact with soil | Common in dogs, less so in humans |
| Ringworm | Fungal | Red, itchy patches | Skin-to-skin contact | Very contagious |
| MRSA | Bacteria | Skin infections | Contact with infected pet | 11.5% of pets in affected households carry it |
Who’s Most At Risk?
- Kids: Especially toddlers who put everything in their mouths.
- Older adults: Weaker immune systems mean harder recoveries.
- Pregnant people: Some infections can cause birth complications.
- Immunocompromised individuals: Even mild infections can become serious.
And while working dogs aren’t necessarily more dangerous, their environments – like flood zones, farms, or hospitals – can crank up their exposure to bacteria and viruses. That means more opportunities for pathogens to hitch a ride home.
How to Lower the Risk
It doesn’t take a hazmat suit. Just smart habits.
- Wash hands after playing with your dog or handling poop.
- Pick up waste promptly. Don’t let it linger in the yard or garden.
- Glove up when digging in soil that might be contaminated.
- Cover sandboxes to keep out neighborhood pets.
- Keep up on vet visits – rabies, deworming, and leptospirosis vaccines matter.
Why Working Breeds Struggle in Pet Roles
People love working breeds. They’re sharp, loyal, athletic, and eager to please. But once they trade in the herding field for a fenced-in backyard or apartment life, problems start to stack up – often in the joints, the gut, or the brain.
Common Health Problems in Working Breeds
| Condition | What It Does | Breeds Prone to It | Impact |
| Hip Dysplasia | Misshapen hip joint leads to arthritis | German Shepherds, Labs, Goldens | Chronic pain, early arthritis |
| Elbow Dysplasia | Poor joint development causes lameness | Rottweilers, Bernese | Limited movement |
| CCL Tears | Torn knee ligament | Labradors, Boxers | Surgery, long recovery |
| Patellar Luxation | Kneecap slips out of place | Border Collies, Shelties | Pain, occasional limping |
| Arthritis | Wear and tear on joints over time | All aging working breeds | Mobility loss, reduced quality of life |

Why It Happens
- Genetics: These dogs are built for tough jobs. That strength often comes with orthopedic baggage.
- Activity Misalignment: A Border Collie meant to herd sheep all day doesn’t do well pacing around a suburban kitchen. Not enough exercise leads to weight gain and behavior issues. Too much, too fast – especially on hard pavement – can injure joints.
- Obesity: Labs are famous for eating anything. But even a few extra pounds can push a dog with hip dysplasia into pain territory. In fact, lean Labradors live almost two years longer than their overweight counterparts.
- Aging: The longer the legs and heavier the build, the more wear and tear. That goes double for dogs with a physically demanding past (think ex-K9 units or retired service dogs).
The Everyday Examples
- A German Shepherd retired from police work starts limping in cold weather. Turns out, early-onset arthritis from years of joint stress.
- A family adopts a Labrador that’s 20 pounds overweight. Within months, he tears his CCL chasing a tennis ball.
- A Border Collie is left home alone all day without a job to do. She starts chewing through furniture – not because she’s bad, but because she’s bored and stressed.
What Pet Owners Often Miss
The shift from “working dog” to “family pet” sounds great in theory – but it only works if the dog’s biological needs are met.
Unfortunately, many owners underestimate just how much support their dog really needs.
Key Risks That Get Overlooked
- Too little exercise leads to obesity, boredom, and destructive behavior.
- Too much intensity – especially on hard surfaces or with repetitive fetch games – can worsen joint issues.
- Ignoring early symptoms like stiffness or reluctance to jump can delay diagnosis of dysplasia or arthritis.
- Poor diet can worsen inflammation and contribute to excess weight.
- Lack of mental stimulation can cause stress, anxiety, or even aggression in intelligent breeds.
Supportive gear like a well-fitted Dog splint can sometimes make the difference between pain management and constant limping.
What You Can Do
There’s no magic pill, but there is a solid plan. A few thoughtful adjustments can spare your dog years of discomfort – and you, a wallet full of vet bills.
Daily Habits That Matter
- Exercise smart. High-energy breeds need 60–120 minutes of daily movement. Prioritize lower-impact options like:
- Swimming
- Hiking on soft trails
- Puzzle feeders for mental enrichment
- Feed for function. Look for:
- Omega-3 fatty acids (salmon oil)
- Glucosamine and chondroitin
- Anti-inflammatory herbs like curcumin and Boswellia (found in Bernie’s Healthy Hips)
- Weigh your dog regularly. A scale doesn’t lie. Even 5 extra pounds can put unnecessary pressure on hips and knees.
- See the vet yearly – minimum. Ask for fecal exams and joint screenings, especially if you’ve got a breed with known risks.
- Train consistently. Lack of structure can cause behavior problems, especially in intelligent breeds like Shepherds and Collies. Basic obedience and agility classes keep them sharp and responsive.
Safety for Both Ends of the Leash
At the end of the day, working dogs and pet dogs have more in common than not. They rely on us for health, safety, and structure. But pretending all dogs have the same needs is a shortcut to trouble.
Whether you’re a handler with a dog in the field or a parent with a Shepherd lounging in your living room, the takeaway is the same: care has to be intentional. That means:
- Staying alert to zoonotic risks, especially in mixed-age or immunocompromised households.
- Meeting the physical and mental needs of working breeds, even when they’re technically “off duty.”
- Recognizing the early signs of orthopedic or stress-related issues – and getting ahead of them.
Final Thoughts
Dogs aren’t machines. Working breeds aren’t plug-and-play pets. And even the fluffiest couch potato can carry bacteria that sends a human to the ER. But none of that means you should panic – it just means you should prepare.
Health risks don’t have to define your relationship with your dog. But they do deserve your attention.
A bit of foresight, a good vet, and a commitment to meeting your dog’s unique needs go a long way toward keeping both of you happy, healthy, and in sync – whether you’re chasing down criminals, chasing frisbees, or just chasing some peace and quiet in the backyard.
