It’s best to avoid visiting dog parks during extremely hot or cold weather to protect your pet from heatstroke or hypothermia. High midday temperatures can make exercise dangerous, especially for brachycephalic breeds or those with thick coats. Similarly, icy conditions can lead to slips and injuries. Early morning or late evening visits can offer cooler, safer conditions. Additionally, avoid the park right after heavy rainfalls to prevent your dog from playing in muddy, potentially parasite-infested water, which can increase health risks.
