Story
Rally turns 5 this July. Unfortunately were having to rehome her for a few reasons. Shes a very high energy girl and were having to keep her separated from our pitbull. Not because of agression or anything, our pitty has hip issues and plays too hard and injures herself. Because of that we dont have much room to keep them separated so that has been a struggle. Rally also struggles with recall and we cant financially afford to fence our entire yard so outside time for her has to be supervised and on leash 24 7. I love my dog very much but I just dont feel like the life were able to provide her is fair to her and I want to find a home for her where she can truly thrive and live her best life.

These pups are in Union Gap, Washington too!

Her adorable docked tail never stops wagging, and she`s always ready for an adventure. She`s a big, strong girl with plenty of energy, making her an excellent companion for an active family who enjoys walks, hikes, playtime, and exploring together.Because Shirley is athletic and clever, she`ll need a secure yard and should not be left outside unattended. She`s known to climb fences if left alone, so she`ll do best with a family that includes her in their daily activities and provides plenty of exercise, enrichment, and companionship.Shirley is looking for a home that will appreciate her fun-loving spirit and give her the guidance and structure she needs to thrive.
