Story
Maia is a beautiful brindle, medium size, mixed (but unknown) breed dog. Her birth date is estimated as 12/29/24 and she was adopted in March of 2025. We have another older dog we wanted to have a buddy and our oldest child wanted a puppy to help train and raise. We fell in love with this girl and decided to go for it. She is house trained and listens very well to the adults of the house and our oldest but she is very high energy and has had some unintentional run ins with our smaller children. We’ve worked a lot on obedience but it’s hard when she feels taunted by little humans walking around with snacks at her eye level all the time. She would do much better and be much happier in a house with older or no children. She loves walks and running around the backyard. A fenced in yard is ideal for her. We are heartbroken to make this decision but confident there is a better fit for her out there and want to find her another home to love her as much as we have.

Story
Stassi is almost 3 years old and she is a very social dog. She needs a lot of attention and she is great with kids and other animals. She is potty trained and knows her commands. She needs lots of room to run and play! I unfortunately work now 2 jobs and feel so bad not being able to give her what she needs. I just want her to go to a good home.

Coronado was found as a stray 12/28/25 with no tag or chip.

Story
I got Rojo in February from our City animal control. He was a stray that was found. He was at first very calm slept a lot, however as he has gotten more comfortable he is very rambunctious. The pound had guessed he was two so I thought he would be calmer but I think their estimate was off. Our moan issue is my mother lives with me and she is older and tiny. He gets excited and knocks her down or jumps on her to play but she has ports for dialysis that we are afraid he will pull. He really is a seeet dog who loves running in our yard. I think that he needs another dog to keep company as he has not met a dog he doesn’t love to play with. I just really don’t want him to wind up on the pins again because he’s a good dog just too much for us.

Story
It breaks my heart to do this, but I’m looking to rehome my dog, Maverick, to the right person or family. Maverick is a 9 year-old prior rescue (birthday October) with a life expectancy of 14-16 years. He’s been with me since he was a pup, and he truly is a loving dog at heart but he’s also a bit complex and needs the right environment to thrive. He is naturally shy and skittish, especially around people. He’s not aggressive at all—just very aloof and prefers to keep his distance. Once he feels safe, his sweet and loyal personality really starts to show. He’s one of those dogs who bonds deeply, just on his own terms. Maverick gets along well with other pets and mostly keeps to himself. He has high anxiety and has had professional training, which has helped, but he still needs a patient and understanding owner. He is housetrained, though he has had a few accidents over the past year as he’s gotten older. Describe him: Stubborn but intelligent, Scared but tough, Loving but independent.
