Dr. St Clair,  Thank you for your free manual download that I referred to daily during our 100 lb Ridgeback- Sheppard mix recovery from TPLO surgery. Your encouraging e-mails and reminders as to what I should be doing to help rehab. Jed, got us through this rigorous post op rehab.  He is doing very well and has free run now of his 4 acres.with no limping.  The only problem was during rehab.3 times per day, 7/8 of a mile each he walked and trained on leash, he marked his territory, and thinks he owns the neighborhood and is very territorial.  When we walk off our property he is on leash. Thank you again for all your support.
