A good outdoor dog kennel needs to keep your dog warm in winter, cool in summer, and dry in British rain. But with prices ranging from £50 to £500+, it helps to know what actually matters. We’ve compared the best UK options for 2026 and created a complete size guide based on RSPCA welfare standards.

Dog Kennel Size Guide (RSPCA Standards)
Getting the size right is the single most important factor. The RSPCA requires that outdoor kennels allow your dog to stand, stretch, lie down, turn around, and wag their tail without touching the sides.
| Dog Size | Example Breeds | Min Kennel (L × W × H) | Recommended |
|---|---|---|---|
| Small (up to 10kg) | Jack Russell, Dachshund, Shih Tzu | 60 × 50 × 50 cm | 70 × 55 × 55 cm |
| Medium (10–25kg) | Cocker Spaniel, Beagle, Staffie | 80 × 60 × 65 cm | 90 × 70 × 70 cm |
| Large (25–40kg) | Labrador, Golden Retriever, Boxer | 100 × 75 × 80 cm | 115 × 80 × 85 cm |
| Giant (40kg+) | German Shepherd, Great Dane, Rottweiler | 120 × 85 × 95 cm | 140 × 100 × 100 cm |
How to measure: Measure your dog from nose to tail base (length) and from floor to top of head (height). Add at least 15 cm to both measurements for the kennel interior.
Wooden vs Plastic vs Composite
| Material | Pros | Cons | Best For |
|---|---|---|---|
| Pressure-treated wood | Natural look, excellent insulation, 15-year guarantee | Heavier, requires occasional treatment, can harbour parasites | Permanent garden kennels |
| Recycled plastic | Maintenance-free, chew-proof, steam-cleanable, eco-friendly | Expensive, less natural appearance | Working dogs, kennel runs, muddy gardens |
| Composite panels | Lightweight, thermally efficient, hygienic, long-lasting | Less traditional look, limited availability | Boarding kennels, professional use |
| Basic untreated wood | Cheap | Rots quickly, poor insulation, short lifespan | Temporary or budget use only |
Our Top Pick: Kennelstore Aston
The Kennelstore Aston combines premium pressure-treated timber with a 15-year anti-rot guarantee, apex roof for superior weather shedding, and galvanised mesh panel options. Available in multiple sizes with optional insulation upgrade. The removable floor makes cleaning straightforward, and the kennel can be paired with a matching run for dogs that spend extended time outdoors.
Best for Giant Breeds: Solway Monster
Made from 100% recycled plastic, the Solway Monster is virtually indestructible. Its free-flow ventilation system prevents condensation without draughts, and the entire kennel can be pressure-washed for deep cleaning. The lifetime guarantee reflects the durability — this is a buy-once kennel for owners of large working breeds.
Winter Preparation Checklist
- ✅ Insulation: Styrofoam panels or thermal liners between walls (RSPCA recommends 10–26°C range)
- ✅ Raised floor: Minimum 5 cm off the ground to prevent frost and damp
- ✅ Draught excluder: PVC strip curtain or internal draught board over entrance
- ✅ Bedding: Thick fleece blankets or raised dog bed (not straw — it absorbs moisture)
- ✅ Roof check: Inspect for loose panels, clear guttering, seal any gaps
- ✅ Heating: Infrared panel heaters are safest (no naked flame, no trailing cables)
Frequently Asked Questions
Is it OK to keep a dog in an outdoor kennel in the UK?
Yes, provided the kennel meets RSPCA welfare standards: proper size, weather protection, insulation, clean bedding, and the dog has regular human interaction and exercise. The kennel should supplement your dog’s living space, not replace it entirely.
What size kennel does a Labrador need?
A Labrador needs a kennel at least 100 × 75 × 80 cm (we recommend 115 × 80 × 85 cm). The dog should be able to stand, turn, and lie down fully stretched without touching the walls.
How do I keep a dog kennel warm in winter?
Use insulated panels (Styrofoam or composite), a raised floor, a draught-excluding door flap, and thick fleece bedding. For extreme cold, add a low-wattage infrared heater with a thermostat. Avoid traditional heaters with exposed elements or trailing cables.
How long do wooden dog kennels last?
A quality pressure-treated wooden kennel (e.g., Kennelstore, tanalised timber) will last 15–20+ years with minimal maintenance. Budget untreated wood kennels typically last 2–5 years before rot becomes an issue.
