What Size Kennel Do I Need for My Dog?

Choosing the right outdoor dog kennel is essential for your pet’s comfort, safety, and well-being. Whether you’re shopping for a backyard kennel or a custom-built residential dog kennel, getting the right size and features makes all the difference. Too small, and your dog feels cramped; too large, and it can be hard to keep warm and cozy. This guide explains how to select the ideal kennel size for your dog, what features to look for, and a few easy maintenance tips to keep it in top shape.

 

1. Kennel Size Guidelines by Dog Weight

A kennel should allow your dog to stand, turn, and lie down comfortably. Measure your dog’s length and height, then choose a kennel that’s a few inches larger in each dimension. The chart below offers general sizing by weight:

• Small dogs (under 25 lbs) – About 24–30 inches long for breeds like Chihuahuas or Shih Tzus.
• Medium dogs (25–50 lbs) – Around 32–36 inches long for Cocker Spaniels or Bulldogs.
  
• Large dogs (50–70 lbs) – Approximately 38–42 inches long for Labs or Shepherds.
  
• Extra-large dogs (70–90+ lbs) – 44–54 inches or more, ideal for Great Danes or Mastiffs.

Always plan for your dog’s adult size and activity level. Puppies grow quickly, and energetic dogs need extra room. If standard sizes don’t fit perfectly, Horizon Structures’ custom dog kennels can be built to exact specifications.

 

2. Key Features of a Great Outdoor Kennel

Beyond size, a kennel’s construction and amenities make a major difference. High-quality kennels combine durability with comfort and are designed to last through all seasons.

 

Insulation and Climate Control

An insulated dog kennel helps maintain a stable temperature—warm in winter, cool in summer. Look for insulated walls, floors, and roofs, plus options for heated floors or air conditioning in extreme climates. Horizon Structures, for example, uses R-13 insulation throughout its dog boxes and offers upgrades like heated floors or AC units for comfort year-round.

 

Ventilation

Fresh air flow keeps your dog healthy. Ventilated kennels prevent humidity, reduce odors, and help with temperature control. Look for windows, air vents, or mesh panels that let air circulate without sacrificing security.

 

Sturdy, Secure Construction

The kennel should be strong, chew-resistant, and predator-proof. Heavy-gauge wire, durable wood, and secure latches keep your dog safe. Horizon Structures adds chew-proof Glasbord™ or poly lining on interior walls and uses keyed latches to prevent clever escapes.

 

Attached Run Space

An attached run gives dogs freedom to exercise safely. Runs should be tall enough to stand and jump, with weather-protected roofing for shade and rain coverage. A dog kennel with run creates the perfect balance between indoor comfort and outdoor freedom.

 

Comfortable Flooring

Flooring should be non-toxic, durable, and easy to clean. Raised floors prevent moisture and drafts, while polyurea-sealed or composite decking is ideal for comfort and hygiene. Horizon Structures uses non-porous polyurea floors inside and pet-safe decking in runs to protect paws and simplify cleaning.

 

3. Maintenance and Upkeep Tips

Even the best kennel needs regular care. Fortunately, modern materials make maintenance quick and easy.

 

Easy-to-Clean Surfaces

Smooth wall and floor finishes like PVC panels or sealed polyurea coatings make it simple to wipe down or hose clean. Horizon Structures uses PVC Trusscore panels, which resist dirt, odor, and stains—perfect for kennels used daily.

 

Good Drainage

Proper drainage prevents standing water and reduces odor. Choose a kennel with sloped floors or integrated drains, or elevate it slightly above ground level. This keeps the space dry and extends the structure’s life.

 

Feeding and Watering Systems

Built-in feeders and automatic watering systems save time and ensure your dog always has fresh food and water. Many Horizon Structures kennels include outside-access feeder boxes or can be upgraded with automatic water hookups.

 

Routine Cleaning

Sweep or hose down the kennel daily and disinfect weekly using pet-safe cleaners. Regular inspections—tightening latches, checking fence panels, and oiling hinges—keep everything running smoothly.

 

4. Balancing Comfort, Function, and Aesthetics

A well-built kennel can enhance your property rather than detract from it. Horizon Structures offers customizable designs to match your home’s architecture, from painted board-and-batten siding to architectural shingles and decorative trim.

You can even add porch overhangs, shutters, or flower boxes for charm. Beyond looks, these upgrades often mean higher-quality materials—better insulation, weather resistance, and long-term durability.

6. Choosing a Kennel That Lasts

When selecting a kennel, prioritize space, safety, and simplicity:

• Space: Enough room for your dog to stand, turn, and stretch.
  
• Comfort: Insulated, ventilated, and shaded areas protect from weather.
  
• Safety: Sturdy, chew-resistant materials and secure locks prevent escape or injury.
  
• Easy Maintenance: Waterproof, washable surfaces make cleanup simple.
  
• Style & Durability: A well-crafted kennel adds curb appeal and long-term value.
