Keep Your Pets Cool as Temperatures Rise! 🐾☀️ As we head into this heat wave, it’s not just humans who are at risk. Our pets rely on us to keep them safe when the mercury climbs. From the "7-Second Paw Test" to monitoring the Equine Index, make sure you’re taking the necessary precautions for your dogs, cats, and livestock. Key Tips: Walk Early or Late: Avoid the midday sun and hot asphalt. Check the Pavement: If it’s too hot for your hand, it’s too hot for their paws! Hydration is Key: Fresh water and ice cubes can make a huge difference. Know the Signs: Watch for heavy panting, lethargy, or stumbling. If you suspect heat stroke, don’t wait. Contact your emergency vet immediately. 🚑 🐾

Temperatures are beginning to warm up this weekend as a ridge begins to move inland. Expect to see temperatures into the low 100s on the warmest days of the heat wave.

With warmer temperatures expected for this weekend and early next week, remember to be safe around area rivers, streams, and lakes. Warm air temperatures do NOT mean warm water temperatures! Some areas of central California can have a difference of 30 to 40 degrees between the two. It only takes 10 to 15 minutes to lose dexterity in 50 to 60 degree water temperatures.
