About Terrier Dogs

Terriers are a diverse group of spirited, energetic dogs originally bred for hunting vermin and small game. They share common traits including boldness, intelligence, and a lively personality. Terrier mixes are popular shelter dogs that combine tenacity with affectionate, entertaining personalities.

Adopting a Terrier brings a feisty, loyal companion who is always ready for action. They are typically alert, brave, and entertaining, with personalities much larger than their size. Their energy and intelligence make them engaging companions for active households.

Local Climate & Pet Care

Winter

40°F to 65°F

Dec – Feb

Mild days and cool nights make winter one of the most comfortable seasons for outdoor pet activities. Occasional frost on early mornings means short-haired breeds may need a light jacket for dawn walks. This is the rainy season, with most of Riverside’s limited annual rainfall concentrated in these months.

Spring

48°F to 80°F

Mar – May

Pleasant warming temperatures bring ideal conditions for exploring Mount Rubidoux and local parks with your pet. Wildflowers bloom across the hillsides after rainy winters. Start transitioning walk times earlier as temperatures begin to climb in May.

Summer

62°F to 95°F

Jun – Aug

Inland heat builds significantly, with temperatures regularly exceeding 93°F. Walk pets only before 8 AM or after sunset, and test pavement temperature before every outing. Ensure pets have constant access to shade and fresh water, and never leave animals in parked vehicles.
