Harleigh Grace is a 10-month-old border collie mix that can't wait to see what is around every corner. As she is still a puppy, she needs tons of daily exercise and training to teach her how to be a good girl. With all her youthful energy, she would be an excellent partner for a runner or someone who enjoys long walks. Harleigh Grace responds to treats and is always ready to learn, so positive reinforcement training will be a fun activity for both of you to do together. This playful pup would thrive in a big, fenced-in backyard in a home filled with plenty of toys and chew bones. If you’re looking for a four-legged friend with an affectionate and adventurous spirit, Harleigh Grace would be the perfect pup for you.
