Mack is a sweet, good-natured guy with a big personality and an even bigger love for FUN! We are hoping the third times a charm for this boy. His second adoptive family has an elderly, grumpy dog who refuses to accept Mack, even tho the other dog in the home loves him. They have therefore decided to find a better home for him. Could it be yours??? He's a playful, energetic boy who absolutely LOVES tug-o-war and enjoys a good game of fetch—even if he occasionally decides the ball is actually his. He's fully housebroken, crate trained, and knows several basic commands. He's also a great leash walker and is eager to keep learning with his people. Mack is a super awesome puppy! He loves playing with our bigger dog, chasing him and being chased. He is super eager to please and would do anything for a treat! He's also a fun fishing companion and loves playing in water! Oh, and we can't forget his adorable underbite that gives him a dorky, pouty expression!! Mack is happiest when he's with his humans and would love a family who enjoys an active lifestyle and can give him plenty of exercise, playtime, and companionship. He's working on feeling more comfortable when his people leave and will thrive with someone who can be patient, consistent, and continue building his confidence and independence. He would love another dog buddy to keep him company and help burn off that boxer energy! If you're looking for a fun-loving, playful companion who will keep you moving, make you laugh, and happily join you for all of life's adventures, Mack may be your guy!
