My dog, Vida, has been going to The Canine Co-Lab since January after a partial CCL tear and their team has been a godsend for us. Vida LOVES seeing Diana and Pam on a weekly basis and I really appreciate how much they enjoy spending time with her too! In the last 4 months with both twice a week and once a week appointments (also doing work at home, of course), I’ve seen Vida’s strength get immensely better, her muscle mass has increased, her energy has gotten substantially better and her balance and core strength is continuing to improve.
I’d highly recommend the team at PAWS and The Canine Co-Lab to anyone looking for a group of highly skilled individuals who genuinely love animals and spend quality time with their clients each time they visit. Vida and I love them!
