St. Bernard

Size

Details
Not good with dogs, Spayed or Neutered, Shots are up-to-date,
Story
Meet Darla, a seven-year-old, 75-pound St. Bernard mix. This gentle giant had a rough start. She was found tied up outside the Maricopa County shelter for hours in the blazing June heat. Understandably, she was scared and reactive at first, but with patience and kindness, Darla has begun to show her true, affectionate self. Darla may be nervous when meeting new people, but give her a little time, and you’ll be rewarded with loyal companionship and leaning hugs that might knock you off balance (literally!). She adores scritches and pets, especially when she can press in close. Darla prefers the solo spotlight and would do best as your one-and-only pet. She walks well on a leash, is easy to handle, and would thrive in a calm, loving home where she can feel safe and appreciated. Her $150 adoption fee includes spay/neuter, vaccinations, microchip, and a free wellness visit at Phoenix Mountain Animal Hospital. To meet Darla, call 602-971-1334 or stop by Thursday–Saturday, 11am–4pm.
