My Mini Dachshund shakes all the time as if he is wet.

The hint for you is that he loves to sleep under a blankie. I have three mini's and one thing I noticed is that they get cold very easily. You might want to try a sweater for your boy. Also check and see if he might have worms or another ailment. It also could be nerves but I would bet on the fact that he's cold. I have blankets on the couch, floor, bed, in their crate and one that is for when we take them for a ride. I also have coats for them along with sweaters. The kennel I got them from has lights over each kennel plus extra heat for the same reason, they reach a point especially in the winter where they get extremely cold. I know that when I get out of bed I immediately reach for my robe as it is much colder when I get out of a nice warm bed, so that may very well be the case for your little boy. So, when he gets up put his sweater on...plus it will help your husband not be so irritated because there won't be "hair flying". Tell him I have asthma and that I haven't had any problems with my dogs or cats triggering or irritating it.

My daschshund,Diva, does this sometimes, mostly when she is guarding something like her food or toy. She does it when she gets excited also. She has seizures sometimes and it could be a result of that, but I'm not sure.

Mine will do this too occasionally. Not sure why. I have 4 of them, Not all of them do it, but one does more than the others. Wow, your hubby must get annoyed easily, there is way more to life to get annoyed over such a small thing like that. Tell hubby get over it, Bogie just shaking it off... lol
