I had a dog, a rednose am-staff, who could smell illness in my husband before anybody knew he was sick.
If I went to my husband to give him a hug or kiss, tje dog would get upset, cry and carry on, and he would try to body block to prevent me from going near my husband.
For a long time, we thought the dog was jealous since the dog was very close to me. It took us a bit to realize what was happening.
Once we figured it out, whenever the dog reacted, I’d whisk hubbie off to the doctor where massive sepsis was always the diagnosis
As a result, the dog was considered to be a service dog. I could take him anywhere, and could reside anywhere w/o issues. We had a certificate for him.
He died of lymphoma cancer after my husband died of a miriade of complications.
Thanks for sharing. God bless you all.
