Somehow all our dogs find a job in our home.
Since June last year Eoos found hers: she guards our health and we call her "nurse Eoos". She wakes Frank if his heart starts beating too fast (supraventricular tachycardia). He can stop this by himself, but often he realises too late it is there. The "double" heartbeat usually starts at night when he is sleeping and goes on until he realises that his heart is the reason for his extreme fatigue.
Thursday, very early in the morning, it happend again and Eoos alerted Frank. She did this a few times before, but we were not certain if it might have been coincidence. Now we are sure "nurse Eoos" is watching at night.
Eoos did wake me a few times in the past months, but we don't know why, communication from dog to human is always difficult. Maybe we will find out, it took a while before we realised why she woke up Frank. Maybe it is related to my thyroid issue, then we will probably never know...
