My dog is having an issue where it seems as though she's suddenly is staring off into blank space, then she starts looking left add right and left and right, if she's responsive it's usually just to look at me not come to me or answer me like usual, she walks in circles over and over again then she's sits or lays and looks left and right all over again, it had sings of two is three different things please help me figure out what's wrong with my dogs. She's a 8 or 9 year old Sheba breed dog not sure the the specific but she was a stray she always had odd behavior but that's just how her breed acts but this is something different at first i thought that certain frequencies caused it but i don't know what it is
