Story
Riley is a sweet, gentle soul with a calm and loving nature. He enjoys peaceful walks, basking in the sunshine, and rolling around in the grass for the perfect back scratch. Attentive and eager to please, Riley is wonderfully food-motivated—he’ll sit like a true gentleman the moment a treat is nearby. He has an especially endearing habit of sitting between your legs or leaning gently against you, happily soaking up head scratches and affection. While he has a playful side and loves attention, Riley is just as content curling up in a cozy spot for a well-deserved nap after some outdoor time. With his balanced mix of relaxed and playful energy, Riley would thrive with a confident, caring person who’s ready to give him the love and companionship he’s been patiently waiting for.

Story
Mia is a very loving and loyal girl. She does great with all people, children and animals. She is almost nine years old. My husband and I adopted her at 3 months old and have loved her since. Unfortunately after having a baby her needs aren’t being met as much as I’d like and we are having a hard time giving her the care we would like to. For example, she needs regular ear cleaning, allergy shots & uti medication which we cannot afford at the moment.
