Story

This gorgeous pup is Pepper! This sweet, soulful girl may start off shy, quietly observing from her favorite cozy hideaway, but give her a little patience and something truly special unfolds. Once Pepper decides you’re safe, she loves deeply. She comes when called, seeks out cuddles, and curls up beside you at night — offering the kind of loyal, wholehearted affection that feels rare and incredibly meaningful. Pepper is an absolute gem in the home — gentle, respectful, and trustworthy. She’s never been kenneled in foster care and hasn’t destroyed a single thing (yes, really!). She’s smart, eager to please, and wonderfully well-mannered. Pepper lives happily with four other dogs of all sizes and enjoys playful romps — and she listens beautifully when it’s time to settle down. Leashes are still a little scary right now , but Pepper is intelligent and wants to learn. With patience, encouragement, and especially a confident canine buddy to show her the ropes, she’ll continue to blossom . Pepper is looking for: A patient, kind adopter A home with another friendly dog ‍ Someone who understands shy or sensitive souls A family who finds joy in watching a dog come out of her shell If you’ve ever dreamed of being a dog’s safe place — the person they choose, trust, and love with their whole heart — Pepper just might be your heart dog.

Macks

Cattle Dog Shepherd (Unknown Type)

Female, 6 yrs 3 mos

Size

(when grown) Large 61-100 lbs (28-45 kg)

Details

House-trained, Spayed or Neutered, Shots are up-to-date,

Story

Meet Macks, a 5-year-old Cattle Dog/Shepherd mix with a heart full of potential and a loving spirit. Macks was surrendered to a high-kill shelter after her previous owner passed away, and she’s now looking for a new family to give her the love and stability she deserves. Initially anxious and a bit flighty, Macks requires some time to build trust. However, once she feels secure, she becomes an incredibly affectionate and well-behaved companion. Macks is not fond of other dogs or cats, so she would do best in a home where she can be the only pet. She will thrive in a household with middle school-aged children or older, or with adults who can provide her with the patience and care she needs to feel at ease. If you're looking for a loyal and loving dog who will become deeply attached to her new family, Macks is ready to bring her devotion and warmth into your home.
