How Do I Keep My Small Dog Healthy?

If you own a small or toy breed dog, you already know that little dogs have big personalities. But keeping a small dog healthy requires more than love and cuddles. Small breeds have unique health needs, nutritional requirements, and vulnerabilities that differ significantly from larger dogs. Whether you have a Chihuahua, Shih Tzu, Pomeranian, Yorkshire Terrier, Maltese, Dachshund, or any other small breed, this guide covers everything you need to know to keep your small dog healthy, happy, and thriving for years to come.

1. Schedule Regular Veterinary Checkups

The single most important thing you can do to keep your small dog healthy is to schedule regular veterinary checkups. Small dogs should visit the vet at least once a year for a full wellness exam, and twice a year once they reach senior age, which for most small breeds begins around 10 to 12 years old.

During a wellness exam your vet will check your dog's teeth, heart, joints, weight, eyes, ears, and coat condition. Many serious health conditions in small dogs — including heart disease, dental disease, and luxating patellas — are far easier and less expensive to treat when caught early.

Do not wait until your small dog is visibly sick to visit the vet. Small dogs are instinctively good at hiding pain and discomfort, which means by the time symptoms are obvious, a condition may already be advanced. Preventive care is always better than reactive care.

2. Stay On Top of Vaccinations

Keeping your small dog's vaccinations current is one of the most straightforward ways to protect their health. Core vaccines for small dogs include Rabies, DHPP (distemper, hepatitis, parvovirus, and parainfluenza), and Bordetella, which protects against kennel cough and is required by most dog daycares and boarding facilities.

Your vet will recommend a vaccination schedule based on your dog's age, lifestyle, and health history. Puppies require a series of vaccinations in their first few months of life, followed by booster shots at regular intervals throughout adulthood. Never skip a booster — even if your small dog seems perfectly healthy — because lapses in vaccination coverage can leave your dog vulnerable to serious and potentially fatal diseases.

3. Feed Your Small Dog a High Quality Diet

Nutrition is the foundation of your small dog's health. Small breeds have faster metabolisms than large dogs, which means they burn calories more quickly and require nutrient-dense food that fuels their energy without causing weight gain.

When choosing food for your small dog, look for a product that lists a high-quality protein source such as chicken, turkey, or salmon as the first ingredient. Avoid foods with excessive fillers like corn syrup, artificial preservatives, and unnamed meat by-products.

Small breed specific formulas are worth considering as they are designed with smaller kibble sizes and caloric densities appropriate for little dogs.

Portion control is critical for small dogs. Overfeeding is one of the leading causes of obesity in small breeds, and even a small amount of excess weight puts significant strain on their tiny joints, heart, and spine. Follow your vet's recommended feeding guidelines and resist the urge to overfeed treats, which should make up no more than 10 percent of your dog's daily caloric intake.

Some human foods that are safe for humans are toxic to dogs, including grapes, raisins, onions, garlic, chocolate, xylitol, macadamia nuts, and avocado. Keep these foods completely out of reach of your small dog at all times.

4. Maintain a Healthy Weight

Obesity is one of the most common and preventable health problems in small dogs. Because small breeds weigh so little to begin with, even one or two extra pounds represents a significant percentage of their body weight and can dramatically increase their risk of diabetes, joint disease, heart disease, breathing problems, and a shortened lifespan.

You should be able to feel your small dog's ribs easily when you run your hands along their sides, but not see them prominently. If you cannot feel the ribs at all, your dog is likely carrying excess weight and you should speak to your vet about a weight management plan.

Regular exercise is just as important as diet for maintaining a healthy weight. Small dogs need daily physical activity, though the intensity and duration should be appropriate for their size and breed. A Chihuahua has very different exercise needs than a Miniature Schnauzer, so speak to your vet about what is right for your specific dog.

5. Prioritize Dental Health

Dental disease is the single most common health problem in small dogs, affecting the vast majority of dogs over the age of three. Small breeds are particularly prone to dental issues because their teeth are crowded into a smaller jaw, which makes them more susceptible to tartar buildup, gum disease, and tooth loss.

Left untreated, dental disease does not just cause pain and tooth loss — the bacteria from infected gums can enter the bloodstream and cause serious damage to the heart, kidneys, and liver. This makes dental care one of the most important and most overlooked aspects of small dog health.

Brush your small dog's teeth daily using a dog-specific toothpaste and toothbrush. If your dog resists brushing, start slowly by letting them lick the toothpaste off your finger before gradually introducing the brush. Dental chews, water additives, and dental diets can also help reduce tartar buildup between professional cleanings.

Schedule a professional dental cleaning with your vet at least once a year, or more frequently if your vet recommends it. Professional cleanings remove tartar that cannot be addressed by brushing alone and allow your vet to identify and treat any developing dental disease before it becomes serious.

6. Protect Your Small Dog's Joints

Joint problems, particularly luxating patella — a condition where the kneecap slips out of place — are extremely common in small breeds including Chihuahuas, Pomeranians, Yorkshire Terriers, and Toy Poodles. While some degree of genetic predisposition exists, you can take steps to protect your small dog's joints throughout their life.

Avoid letting your small dog jump on and off high furniture repeatedly, as the repeated impact can stress their joints over time. Use ramps or steps to help your dog access sofas and beds safely. Keep your dog at a healthy weight, as excess weight dramatically accelerates joint wear and tear. Consider joint supplements such as glucosamine and chondroitin, particularly as your dog ages — speak to your vet before starting any supplements.

If you notice your small dog limping, favouring a leg, reluctant to climb stairs, or showing signs of pain when moving, see your vet promptly. Luxating patella and other joint conditions are very manageable when caught and treated early.

7. Groom Your Small Dog Regularly

Regular grooming is not just about keeping your small dog looking their best — it is an essential part of their overall health and wellbeing. Depending on your dog's breed and coat type, grooming needs will vary significantly.

Long-coated breeds like Shih Tzus, Maltese, and Yorkshire Terriers require daily brushing to prevent painful matting, which can pull on the skin, trap moisture, and cause skin infections. Short-coated breeds like Chihuahuas and Miniature Pinschers require less brushing but still benefit from regular grooming sessions to remove loose hair and check the skin for any abnormalities.

All small dogs require regular nail trimming — typically every three to four weeks. Overgrown nails cause discomfort when walking, affect your dog's gait, and can eventually curl back into the paw pad, causing pain and infection. If you are uncomfortable trimming nails at home, a professional groomer or your vet can do this quickly and safely.

Ear cleaning is particularly important for small breeds with floppy ears like Cavalier King Charles Spaniels and Cocker Spaniels, as moisture trapped in the ear canal creates an ideal environment for bacterial and yeast infections. Check your dog's ears weekly and clean them as recommended by your vet.

8. Socialize Your Small Dog From an Early Age

Socialization is one of the most important investments you can make in your small dog's long-term health and behaviour. Dogs who are well socialized from puppyhood are significantly less likely to develop anxiety, fear-based aggression, and stress-related health problems throughout their lives.

Expose your small dog to a variety of people, environments, sounds, and other dogs from as early an age as possible. Puppy classes, dog-friendly parks, and structured small dog daycare are all excellent ways to build your dog's social confidence in a safe, controlled environment.

It is important to socialize small dogs specifically with other small dogs. Small breeds that are regularly overwhelmed or frightened by larger dogs can develop chronic anxiety and fear-based behaviours that are difficult to reverse in adulthood. A small-dog-only daycare environment — like Puppylove Dog Daycare in Waterloo, Ontario — provides the ideal socialization setting for small breeds to build genuine confidence around dogs their own size.

9. Provide Daily Mental Stimulation

Physical exercise alone is not enough to keep your small dog healthy. Mental stimulation is equally important for your dog's cognitive health, emotional wellbeing, and behaviour. Bored dogs are more likely to develop destructive behaviours, excessive barking, and anxiety.

Puzzle toys, food-dispensing toys, training sessions, nose work activities, and interactive play are all excellent ways to keep your small dog's mind active and engaged. Even short training sessions of five to ten minutes per day provide significant mental stimulation and strengthen the bond between you and your dog.

Dog daycare is also an excellent source of mental stimulation.

A day spent interacting with other dogs, exploring new smells, and engaging in supervised play provides far more mental enrichment than a day spent alone at home. Dogs who attend regular daycare typically sleep better, behave better, and show fewer signs of anxiety than dogs who spend long periods alone.

10. Never Skip Parasite Prevention

Fleas, ticks, heartworm, and intestinal parasites are real threats to your small dog's health, and prevention is far easier and less expensive than treatment. Speak to your vet about a year-round parasite prevention plan appropriate for your dog's lifestyle and the specific risks in your area of Ontario.

Small dogs are particularly vulnerable to the effects of parasites because of their small body size. A flea infestation that a large dog might tolerate can cause severe anaemia in a tiny Chihuahua or Maltese. Heartworm, transmitted by mosquitoes, can be fatal if left untreated. Monthly preventive medications are safe, affordable, and highly effective — make them a non-negotiable part of your small dog's health routine.

11. Watch for the Warning Signs of Illness

Because small dogs are so good at hiding discomfort, knowing the early warning signs of illness is critical for every small dog owner. Contact your vet promptly if you notice any of the following in your small dog:

Loss of appetite or sudden changes in eating habits. Lethargy or unusual tiredness. Vomiting or diarrhea lasting more than 24 hours. Excessive thirst or urination. Coughing, wheezing, or laboured breathing. Limping or reluctance to move. Changes in coat quality, excessive scratching, or skin irritation.

Cloudy or discharge-producing eyes. Unusual lumps or bumps. Sudden weight loss or gain. Trust your instincts as a pet owner. You know your dog better than anyone. If something feels off, it is always better to call your vet and be reassured than to wait and have a minor issue become a serious one.

12. Give Your Small Dog Plenty of Love, Routine, and Security

Finally, one of the most important — and most underrated — factors in your small dog's health is emotional security. Small dogs are deeply social animals who thrive on routine, consistency, and close bonds with their owners. Dogs who feel safe, loved, and secure in their environment show significantly better physical and mental health outcomes than dogs who experience chronic stress or instability.

Maintain a consistent daily routine for feeding, walks, playtime, and sleep. Provide a comfortable, safe space where your dog can rest undisturbed. Invest in quality time with your dog every single day. And when you cannot be there, make sure your dog is in a safe, nurturing environment — whether that is with a trusted dog sitter, a family member, or a reputable small dog daycare in your area.
