At this age, if they change personalities-get aggressive- it very well may be thyroid issues.
My vet and her husband raise and show anatolians and she also specializes in other large/giant breeds as well. When these dogs have aggression issues and/or skin and coat issues she will always do a full thyroid panel and within weeks these same dogs that are being considered for euthanasia are back to themselves!
You obviously care for your dogs allot- please consider all the advice you are getting.
Keep your GS safe and seperate before there is a true emergency.
