Story
Maizey turned 8 years old around July 4th, 2026. She was adopted from Lifeline Puppy Rescue. She is the best dog. She does bark to alert because of her breed, heeler mix. Otherwise she is a great listener. Low maintenance dog and 45 lbs. My life circumstances don’t allow me to give her the time that she deserves. Looking for a loving home that she can get the attention she deserves.

Story
Ladybird is beloved member of our family. She is good with kids and most dogs. Unfortunately, she does not get long with our older dog specifically that had resulted in a couple fights. We have another dog she gets along great with but we cannot risk the older dogs safety. The vet is unsure what kind of dog she is but thinks she is either some sort of rednose coonhound or a rhodesian ridgeback mix. Ladybird is calm most of the time, loves to cuddle and play tug of war. It breaks my heart but I would like for ladybird to have a home that is safe for her.

Story
Meet Honey ❤️ Honey is a wonderful 3-year-old girl looking for a very special home. She is exceptionally well trained, affectionate, calm and confident. She is completely housebroken, crate trained, non-destructive, excellent on leash and not overly vocal. She’ll happily walk or hike for miles, then curl up and snuggle when it’s time to relax. She’s also fantastic with our cat—we jokingly call Honey the cat’s “emotional support dog” because they’re constantly cuddling. This decision is heartbreaking. Honey has developed serious aggression toward our 14-year-old female dog, despite the two having been best friends for nearly three years. We have worked extensively with a veterinary behavior professional and have been advised that their conflict is unlikely to be safely resolved long-term. We will be completely transparent about Honey’s behavioral history and professional recommendations. She is deeply loved and very bonded to her people. She’s truly an incredible dog.

Sadie

Mutt

Details
Good with kids, Not good with dogs, Good with cats, House-trained, Spayed or Neutered, Shots are up-to-date,
Story
Meet Sadie, an 11-year-old sweetheart looking for her next (and hopefully final) loving home. Sadie was rescued as a stray in Arizona and has the look and spirit of a Caribbean "potcake" dog; scrappy, smart, and full of heart. She was adopted in 2016 by a foster family who also had a police canine, so she learned crate and potty training early and has been rock-solid on both ever since. Sadie is a true homebody who thrives in a family setting. She gets along great with cats and has always lived peacefully with one other dog, though she prefers to be the only dog (or very selective about canine friends). Around the house, she's earned the nickname "the Sheriff". She keeps a watchful eye on every cat and dog in her domain, making sure everyone behaves! More than anything, Sadie is a love bug. She adores belly rubs and head scratches, and isn't shy about asking; she'll nudge, lean, and paw her way into your lap if you let her. She's affectionate, a little pushy in the sweetest way.

Louie

Mutt

Male, Senior
Denver, CO
Size
(when grown) Large 61-100 lbs (28-45 kg)
Details
Not good with kids, Not good with dogs, Not good with cats, House-trained, Spayed or Neutered, Shots are up-to-date,
Story
Louie is a 9 1/2, 70 lb sweet, loyal, goofy, easygoing companion. His perfect day includes a leisurely walk, a game of tug, snack time, a long nap in a sunny spot & curling up next to his favorite person. He's the perfect balance of enjoying a little adventure while also being content to spend the afternoon relaxing at home. Louie is smart, well-mannered & knows sit, stay, down, wait, drop it, and leave it. He's potty-trained, adores his crate, rides beautifully in the car, has gone camping & settles easily around the house. He loves walking but is occasionally dog reactive. After more than eight wonderful years with our family, we're searching for a home where Louie can enjoy his golden years. This heartbreaking decision comes after extensive behavior training to help him adjust to our new baby. While he is now able to remain calm when the baby is across the room, he can still be reactive when she's nearby. Because of this, we're looking for a new home that is pet- and kid-free.

Story
Archer is the sweetest, most cuddly boy. We do not know his past, but it seems that he was abused as he does not like of everything. Archer does not like most dry dog food, but loves homemade food (the the Farmers dog) and canned food. He has separation anxiety and would do best with someone who is going to be with him all day. He is very good with kids from babies to preteens, his best friend is a cat, and he loves to play with other dogs.

Story
Picked her up as a stray. In Hawaii another family saw her tied to a street sign by a rope on the side of the road and took her in, but they couldn't keep her so we took her. Teresa was her name when we got her. She was ~4 years old at that point, but we don't know for sure. We suspect she had puppies at some point in the past, but are unsure. She is spayed. She is GREAT with people and cats. She has had a couple bad interactions with our other dog, Ziggy, during high stress times, like the move from Hawaii. She bit him (not to kill, it was his ear or side of face, we think it may have been trauma or a dominace thing). Otherwise she was always good with him. They are about the same age and size and are the same breed. Because of that I think it's possible there could be an issue with other dogs, but not necessarily. There could be some caution exercised. I feel that's important to know.
