Kristi,
Sampson has the best mommy in the world! I am glad to hear you decided to have surgery! I see so many owners do the wrong thing. This type of Surgery when done by a Board Certified Orthopedic Surgen is very successful. I have done a lot of post surgery care for this type of problem.
Please follow Doctors order when you get him home!!! We had one owner let his Doxie run and jump up the stairs 3 weeks after surgery and caused more damage!
Good luck Sampson!!! Easy does it and mom It's ok really he will be ok.
If it helps at my Hospital us Technicians love the big, king size canines the most and they get extra special care and love and kisses from us.
