That is VERY interesting, I am glad you got it under control. With Cutty I know it isnt a sugar issue per se and he rarely actually has the tremors even. When he does have one he seems to get over it fast if I get him distracted by something. For him it seems to help to get him to just focus on something else then they stop. The fact that he has had them rarely lately like maybe 3 a year to me makes me think it isnt a sugar thing, although I DO know food makes a diff cuz he got them more at one point and they stopped with food change. But now he is steady with his food so not sure what would be the cause mainly now. Especially since the few times he does get them it is usually at night when he is sleeping. I wonder if every dog can get them for many different reasons maybe?
