Dogs will investigate, chew, and interact with anything in their environment. Your cooling system must account for this behavior:

• Chew-Proof Cord Protection: All electrical cords must be enclosed in metal conduit or heavy-duty cord protectors. Dogs can chew through standard plastic insulation in seconds, causing electrocution.
• Secure Mounting: Cooling units must be firmly secured to prevent tipping or falling. A 70-pound dog jumping against an unsecured unit can cause serious injury.
• Temperature Monitoring: Install a wireless thermometer with alerts to monitor interior temperatures. Set alerts for temperatures above 85°F and below 45°F.
• Emergency Shutoff: Install an easily accessible emergency shutoff switch outside the dog house for quick power disconnection in emergencies.

Emergency Warning Signs

Recognize these heat stroke symptoms and seek immediate veterinary care if observed:

• Early Warning Signs: Excessive panting, drooling more than normal, restlessness, bright red gums
• Moderate Symptoms: Vomiting, diarrhea, mental dullness, loss of coordination
• Severe Emergency: Collapse, seizures, body temperature over 104°F, unconsciousness
• Immediate Action: Move dog to cool area, apply cool (not ice-cold) water to body, transport to emergency vet immediately

⚠️ NEVER leave your dog unattended in extreme heat, even with cooling systems. All mechanical systems can fail, and your dog’s life depends on your vigilance.
