This past Monday when DH got home from work, he walked into Chloe having a head tremor.
She's had head tremors since the day we brought her home almost 4 years ago. She is hypothyroid and is on .5 mg of soloxine 2x a day. Her labs were just done (2 weeks ago)- clinically she is greyt. The tremors tend to come at the very beginning of spring, during extreme stress and other times, that I haven't been able to pin point.
Someone on GT told me to give her a piece of cookie when this happens and sure enough, it stops automatically.
Prior to the head tremor on Monday, the last 2 tremors she had was in December '09. I did notice that they seemed a little stronger and it took more than the little piece of cookie to make it stop. I beleive I had to give her a whole chicken strip rather than a little piece.
Rich said that the tremor on Monday was the worst he has ever seen and it took almost 3 full chicken strips to make it stop.
I emailed my vet. Apparently, I did not make it clear about giving Chloe the chicken strip and she thought that I think it has something to do with hypoglicemia which I know is not the case. It's just the act of concentrating that causes her to stop tremoring.
This is the email and I was wondering if anyone thinks of anything else to do? In addition, Chloe's gait is off. I think it's her front left. She does have an old racing injury that causes that to flare up a couple times a year. Chloe is 5.5 years old and my girlie girl, sweet biotch. She is perfect.

...I'm a little concerned about the progressive nature of Chloe's head tremors. I don't think they're related to hypoglycemia, so I think the previous response to treats, etc. is probably coincidental. There are dogs that experience mild intermittent head tremors and they never progress to more than that. However, there are others that will progress to true seizure activity. There is no test to diagnose head tremor disorders or epilepsy. The way to do it is to rule out all the other causes of seizures (i.e cancer, liver disease, etc). Usually this is accomplished with bloodwork and it may be appropriate in Chloe's case.
However, greyhounds, as you know, like to be different. They do have very thick blood which likes to clot spontaneously and makes them more prone to throwing bloodclots and having "mini strokes" similar to TIA's in humans. The treatment for such dogs is to start them on low dose aspirin therapy.
Again, very difficult to know exactly what is going on. I wouldn't worry yet as the signs are still mild, but I think it's worth running full bloods with a bile acids test to rule out an underlying problem. If all is well, watch her. If the tremors continue, we may want to start her on the aspirin....
