Sierra was adopted through our organization 3 years ago and due to her owners circumstances changing she is now searching for a new home.  Please read below to learn all about her!  She is in foster, so if you are wanting to meet her begin by filling out an adoption application and then we can set up a meting.

Sierra is a 4 year old Border collie mix that been a wonderful companion for the past 3 years.  My situation has changed at home, so I’m not able to take care of her in the way she needs and I feel it would be best to find her a new home.

Sierra is very social, intelligent and trainable. She has a very high energy level, and loves to play. Whether it’s playing fetch with a ball or tug-o-war with her favorite chew toy, she’s all about having fun. She also has a sweet side, and is great with people that come into my house or with friends around the neighborhood (she loves being around people and other dogs), greeting them with an exuberant tail wag and even rolling on her back to see if she can score a tummy rub. She loves to play with her dog friends in the neighborhood, and is great in a kennel that has the dogs playing together during the day.

Our daily routine has been walks followed by a bike ride (or should I say horse race, check out the pictures!). Every morning after our walk, we’ll do the same loop with her running beside my bike. It’s starts and finishes with a sprint, often going up to 25mph. She loves it and jumps with excitement every day when we’re getting ready to go. She also loves hiking and playing in the creeks in Umstead Park.

It would be best for Sierra to be in a home without other dogs, as she has been aggressive with other dogs in her space on a few occasions when she wanted a ball or high-value food. Sierra would do best with someone who is aware of a border collie’s characteristics and is willing to put the time into her exercise/training.

I’m happy to share many more details about Sierra if you’re interested.
