Hello, my name is Millie. I am a 6 year old female Retriever/Labrador/Shepard mix. I love outside time to run around and cuddles with my owners. I wish I could stay with my family, but I think I would thrive better in a home with more attention. Please help me find a good home!

Story
We got Binner when he was a puppy . He is a sweet and loving dog he just needs to be in a home who doesn’t have little kids . We have 4 kids, 2 of which are toddlers. He is okay with the older ones but gets nervous/anxious around the younger ones. We just unfortunately don’t have the time to give him the attention and love he needs or time to play and daily walks . He needs a loving home preferably a home without young children so he can get all the love and attention he needs . We are very sad we have to do this ! It breaks our heart . But we want what is best for our family and Binner ❤️

Story
Banner is a 4 year old playful pup. According to an Embark DNA test, hes mostly pit bull and pyrenees with some labrador, golden, and pug mixed in. We adopted him from the Humane Society of Missouri when he was about 4 months. He grew up with another large dog and lives most of his days inside on a couch or outside in a secure fenced-in yard. Hes good at chilling at home while weve been at work. Hes generally good with people but can get hyper about meeting new humans. Hes completely house trained and knows not to jump on people. However, he is not leash trained. Our hearts are broken because we love him dearly and he is a such a special pup. However, within the last year, he has acted up a few times regarding food aggression. We believe this is due to our baby human addition(s) to our family within the past year. We know he will be a really good fit for a family with older kids or a couple or just an adult who will cuddle him at the end of the day.

Story
Hello! This is Aphrodite. She is an absolute couch potato, loves sunbathing, and does well with kids. She is both potty and crate trained, and due to her age, is pretty low energy. She has bursts here and there, but it only lasts for a few minutes. She is not currently experiencing any medical needs. She does well with other animals, and would prefer, though not require, a slower paced home. She doesn't like thunder or fireworks, but she is an absolute snuggle bug! She is free to who promises to love her the way that I have.

(when grown) Med. 26-60 lbs (12-27 kg)
Details
Good with dogs, Needs special attention, Spayed or Neutered, Shots are up-to-date,
Story
Meet Patrick, one year old. He's an anxious little guy and will take time to settle (3-4 weeks to see his trusting side with humans - dogs earn his trust earlier). Patrick feels safe under furniture, esp. beds, but he also loves cuddling once he's trusting. He has done very well having my dog as a reference for what's safe and may do well in a home with another dog that can help him learn the ropes. My mom adopted Patrick in Jan 2026 but recently moved into assisted living. She was not in a place to give Patrick the best coaching. He's still getting house trained and learning routine. We are about 70% there - accidents still happen about 3-4x a week - notably, accidents only occur when I'm home, not when I'm out - a skilled trainer may have no issues. Light nipping issues when playing (no biting). Patrick will do best in a patient, quieter home (but still engaging - loves playtime) that can give him time to settle in, but he's definitely on the way to being the best good boy.
