Fall in Calgary is a season of rapid change. Temperatures can swing 20°C in a single day, daylight shrinks noticeably each week, and the landscape transitions from summer green to winter white — sometimes in a matter of days. Here's how to keep your dog safe and comfortable through the transition.
Weather Transitions
Calgary fall weather is notoriously unpredictable. September can bring both 25°C heat and snow. October sees the first sustained cold. By November, winter has typically arrived.
**Layer strategy:** Start carrying a dog coat in your car by mid-September. You may not need it on a warm afternoon, but an unexpected cold snap or wind shift can make it essential. A lightweight, packable coat is ideal for fall's temperature swings.
Hunting Season Awareness
Alberta's hunting seasons begin in fall, primarily September through November. While hunting doesn't occur within Calgary city limits, dog owners hiking trails near the city (Bragg Creek, Kananaskis, Ghost Wilderness) should be aware:
Mushroom Dangers
Fall rains bring mushroom growth in Calgary's parks, particularly in forested areas like Edworthy Park, Fish Creek, and Bowmont Park. While most are harmless, some species in Alberta are toxic to dogs.
**Prevention:** Watch your dog closely in areas where mushrooms are growing. If your dog eats a mushroom, try to collect a sample, photograph it, and contact your veterinarian immediately.
Shorter Days: Visibility Gear
By late October, Calgary is dark by 6 PM. By late November, sunset is before 5 PM. This means most weekday dog walks happen in darkness.
