My dog seems to have occasional seizures, for lack of a better term.
Seems to occur randomly and not very often; maybe 4 times in the last year that I've witnessed.
When it occurs, she appears weak in her rear legs with a little bit of shaking as she tries to walk and her eyes appear far away.
It passes very quickly, never lasting more than 10 seconds.
She's up to date on her shots, takes Nexgard and heart worm pills once a month.
