Story

Meet Lucy D! Lucy is a 5-year-old, 100-pound mixed breed girl with a BIG personality and an even bigger heart. She recently spent some time out of boarding on a daycation, and honestly? She was a total star. Lucy is energetic, happy, affectionate, and absolutely thrives around people. She loves attention from everyone she meets, including kids, and will happily lean in for pets, roll onto her belly for cuddles, and shower you with kisses. Despite her size and excitement, she settled beautifully throughout the day and even relaxed calmly beside a table at Community Beer Co. while taking everything in. She's also a social butterfly with other dogs! Lucy met several dogs throughout her daycation, including tiny dogs, and walked calmly alongside them. Her boarding team reports that she is friendly with all dogs and loves to play. Lucy is house trained, crate trained, rides perfectly in the car, takes treats gently, and rarely made a peep all day. She does have some strength on leash when excited, but once she settles in, she becomes much easier to handle. Lucy came to DPA through the Dogs Matter program after her owner made the incredibly selfless decision to surrender her while focusing on their recovery journey. Unfortunately, Lucy's previous foster was unable to continue fostering, so she is currently stuck in boarding and urgently needs a foster home. Lucy is ready to love someone with her whole heart. She just needs someone willing to give her a chance. All Dallas Pets Alive adoptable pets are spayed or neutered, microchipped, and up to date on vaccines upon adoption.

Story

Hello, World! My Name is Zeke!They call me a `big boy,` but honestly, I think that just means there is more of me to love. I’m sitting here in my kennel, looking out with my big brown eyes, just waiting for the moment the right person walks through the door and says, `That`s him. That`s my boy.`I might look large and strong, but my heart is pure mush. I’m the kind of guy who wants to be your loyal sidekick. Whether you want to go for a brisk walk around the neighborhood or lean back on the couch for a movie marathon, I am fully on board. I’ve got a handsome smooth brown coat, a very boopable nose, and a proud little white stripe on my chest that my friends at the shelter say looks like a tuxedo tie.What I’m looking for in a family:• A cozy spot to rest: I promise to keep your feet warm.• Daily adventures: A nice yard or regular walks to stretch my legs.• Plenty of head scratches: It`s my absolute favorite thing.
