How long of a healing process of the pectoral muscles for those that have pulled/tore extensively?  And what has been done to help them heal therapy wise. I have been doing acupuncture/chiropractic/massage/red laser light therapy.  This horse got hurt Jan 2018 and spent the year rehabbing and was able to rope some steers on him Jan 2019 then had an unfortunate accident on Feb 20, 2019 and back to square one I feel.  I have him on 707 joint essentials 6-1 for maintenance and this week been putting BOT quick wraps on at night since they are brought in at night and turned out to pasture during the day.  

Any help and or ideas would be greatly appreciated as I am just devistated..

Have you had him x rayed? I just got done posting about my horse that I had x rayed due to problems in his neck. They found arthritis, injected it. It helped. I decided to go w/x rays BEFORE chiro just in case. My post is: C6C7 arthritis. 

Yes, we have had him xrayed before he had this last accident.  He has been adjusted twice now in C3-6 since then.  I will check your post out, Thank you
