An Overview of Healthy Small Dog Breeds

Small dog breeds are becoming increasingly popular as pets for urban and suburban families. Their compact size makes them well-suited for smaller homes, and their energetic and affectionate personalities endear them to owners.

However, some small breeds are predisposed to certain health conditions due to selective breeding and their petite frames.

By choosing the healthiest small dog breeds and providing proper care, owners can promote wellness and longevity in their petite pooches.

What Qualifies as a Small Dog Breed?

The American Kennel Club defines a small dog breed as one that typically stands less than 15 inches at the shoulder and weighs under 40 pounds as an adult. Examples of popular small dog breeds include the Havanese, Shih Tzu, Yorkshire Terrier, Toy Poodle, Cavalier King Charles Spaniel, and many more. These pint-sized pups make loyal companions when their health and welfare needs are met.

Characteristics of Healthy Small Dogs

Several factors influence health and wellness in small dog breeds:

  • Genetics: Some small breeds are predisposed to orthopedic, respiratory, cardiac, neurological, endocrine, and eye disorders due to selective breeding. Reputable breeders screen breeding dogs.
  • Nutrition: Quality commercial or home-prepared diets support immune function, mobility, organ health, digestion, healthy weight, skin and coat quality, and longevity.
  • Exercise: At least 30-60 minutes of daily exercise meets activity needs for most small breeds and prevents obesity.
  • Preventive veterinary care: Annual exams, diagnostic screening, and vaccinations prevent or catch issues early.
  • Grooming: Consistent grooming prevents painful mats and skin issues and allows owners to monitor lumps, lesions, etc.
  • Mental stimulation: Games, training, and toys prevent boredom and behavior issues common in some small breeds.
  • Safe environments: Due to their small size, these dogs require supervision and safe spaces free of fall and ingestion hazards both indoors and outdoors.
