Hi,
My yorkie shakes/quivers/trembles/ has muscle spasms occasionally and without any apparent reason. Please see the video located here:
.
We will be taking him to the vet but I would like your input as well in the event there is nothing conclusive the testing is done.
He is very healthy overall (ok during basic physcial exams, is happy and healthy 99% of the time) however has the following other issues which concern me, albeit not to the extent the shaking does:
-if he has a plush toy he will often bite into it and sit in one spot breathing heavily as he bites into it(appears to be some kind of anxiety)
-sometimes after he humps (he is neutered) the tip of his penis will not naturally go back into its sheath and requires 'help'
-he is very sensitive to loud-pitched noises. For example he will be very upset if the smoke alarm rings and will hunt any dish towel (which he noticed was waved at the source one time) until he can throw it around.
-when he is sleeping he is startled when his back is touched and will growl and bite (as a reaction to being startled)
If you could help it would be very much appreciated.
