◦ Heat plus humidity
Worse than Dallas because the humidity blocks evaporative cooling.
Houston summers are the country's worst for dogs. 90°F at 85% humidity feels like 105°F to a panting dog. Surface temperatures on open ground are the same as Dallas, but dogs cool slower because their main cooling mechanism (evaporation from the tongue) loses efficiency in saturated air.
The summer routine: early-morning or post-sunset visits, water-adjacent parks like Johnny Steele or Millie Bush (the three ponds at Millie Bush are the single best summer asset in Houston), and watching closely for heat exhaustion signs.
◦ Practical info
What to know before you go.
- Vaccinations: Harris County requires current rabies plus a county tag ($16 per year for spayed/neutered).
- Hours: Houston Parks dog areas are dawn to 11pm. Millie Bush is dawn to dusk.
- Leash law: Texas has no statewide leash law. Houston requires leash outside designated areas.
- Post-storm drainage: Bayou-adjacent parks can flood. Johnny Steele closes for 24 to 48 hours after major rain events.
- Heat signs: Excessive panting that doesn't slow in shade, drooling, wobbly gait. Leave immediately. Cool water on belly, not head.
