Big personalities packed into a very small footprint!

Did you know? Small dogs typically live significantly longer than large breeds. Chihuahuas commonly reach 14 to 16 years and Dachshunds 12 to 16, while Great Danes average only 7 to 10 years. The reason is not fully understood, but metabolic rate differences are thought to play a role.
Housing & Setup
Small dogs (under 20 lbs) are well-suited to apartments and smaller homes, but still need daily walks and indoor enrichment. Their small size means they can get cold quickly in winter: consider a dog jacket for outdoor walks below 45 degrees F. Watch for 'small dog syndrome' -- a pattern where small dogs are allowed behaviors (jumping, snapping, demanding) that would be corrected in large breeds. Consistent training matters regardless of size.
Diet & Feeding
Small breeds have faster metabolisms and higher caloric needs per pound than large breeds. Feed a small-breed specific formula with smaller kibble size, which is easier on small jaws. Small dogs are prone to obesity from overfeeding or excess treats, which puts serious strain on their joints and organs. Hypoglycemia (low blood sugar) can affect toy breeds, especially puppies: feed multiple small meals daily and monitor closely.
Enrichment & Handling
Despite their size, small dogs were often bred for specific jobs (ratting, hunting, herding). A Dachshund needs to use its nose; a Jack Russell Terrier needs to run and problem-solve. Match enrichment to breed history. Scent games, agility, and trick training are excellent for small breeds. Avoid the temptation to carry them everywhere: small dogs that never walk develop poor confidence and reactivity.
Health & Common Issues
Small breeds are prone to: dental disease (teeth are crowded in small mouths -- brush frequently), luxating patellas (kneecap slipping), hypoglycemia, tracheal collapse (use a harness, not a collar), and heart disease in older age (Cavalier King Charles Spaniels especially). Eye issues are common in brachycephalic (flat-faced) breeds like Pugs and French Bulldogs. Annual vet checks are essential.

Frequently Asked Questions
Why should small dogs wear a harness instead of a collar?
Tracheal collapse is a real risk in small breeds, and a collar puts pressure directly on the windpipe every time the dog pulls. A harness spreads that force across the chest instead. This is one of the few pieces of small-breed gear advice that is genuinely about anatomy rather than preference.
What is small dog syndrome?
It is the pattern where small dogs are allowed behaviors that would be corrected immediately in a large breed: jumping on people, snapping, demanding attention. The dog is not being difficult, it is being trained by inconsistency. Consistent rules matter regardless of size, and a 10 lb dog that has never been told no is genuinely harder to live with than a well-trained 80 lb one.
Why are small dogs so prone to dental disease?
The same number of teeth are crowded into a much smaller jaw, which traps food and plaque in places a larger mouth would keep clear. That crowding makes frequent brushing more important in small breeds than in large ones, not less, and it is worth raising specifically at every annual exam.
What is a luxating patella?
It is a kneecap that slips out of its groove, and it is one of the most common orthopedic problems in small breeds. Owners often notice it as a skipping step or a brief hop before the dog carries on normally. Annual vet checks with a patella assessment are the standard way to track whether it is progressing.
Why do toy breed puppies need several small meals a day?
Hypoglycemia, low blood sugar, can affect toy breeds and is most dangerous in puppies. Their small energy reserves run down fast between meals. Feeding multiple small meals daily and watching for lethargy or wobbliness is the practical prevention, alongside a small-breed formula with kibble sized for small jaws.

Fun Facts
🐶 Three Eyelids
Dogs have three eyelids. A third one called a nictitating membrane helps protect the eye. It is whitish pink, tucked under the lower lid near the nose, and it slides across the eyeball when needed, guarding it from scratches as a dog pushes through brush.
🐶 Unique Nose Prints
Every dog's nose has its own pattern of tiny bumps and grooves, and it stays the same over time: a true doggy fingerprint! Nose print ID isn't new, either. Since 1938, the Canadian Kennel Club has accepted inked nose prints as proof of a dog's identity.
🐶 Dogs Dream Too
Dogs probably dream! Their sleep looks remarkably human, with REM, the stage when people dream. That's when you'll see twitching legs, wagging tails and little noises. Dogs can't tell us for sure, but one expert says they dream doggy things: pointers point at dream birds, and Dobermans chase dream burglars.
