Small breeds, such as Chihuahuas, Yorkies, Pomeranians, Maltese and Pugs, often live long lives, but they come with specific health risks that deserve attention.
Dental disease
Small mouths mean crowded teeth, which trap tartar and bacteria. Many small dogs develop dental disease early. Brush daily, schedule regular dental exams and ask your vet about professional cleanings.
Collapsing trachea
In some small dogs, the windpipe rings weaken and flatten, causing a dry, honking cough, especially with excitement, pulling on a leash or drinking. Use a harness rather than a collar, keep your dog at a healthy weight and avoid smoke and irritants. A persistent cough needs a vet's attention.
Kneecap problems
Patellar luxation, where the kneecap slips out of place, causes skipping or hopping on a back leg. Mention it at your next exam.
Heart disease
Mitral valve disease is common in older small dogs. Coughing, tiring easily and faster breathing at rest are signs worth reporting.
Low blood sugar in toy breeds
Very small puppies can develop dangerous drops in blood sugar if they miss meals. Weakness, wobbling or seizures are an emergency.
Fragile bones and backs
Jumping off furniture can cause injuries. Use ramps or steps, and ask about back problems in long-bodied breeds.
Weight matters most
Even a pound or two of extra weight is significant for a small dog. Measure food and limit treats.
Care that fits small dogs
For routine exams and dental cleanings, find a nearby veterinarian.
