Shaking/Trembling 3yr old Cocker Spaniel

Question
Our 3yr old female cocker spaniel has been trembling/shaking for about a week - not sure if related but she was at the groomers that day and that night she started -- it only happens when she is sleeping or just sitting.  She will jump up and run around if you call her during the episodes -- she is eating well and very energetic.  She was diagnosed with seizures about 6 months ago and has been on potassium/bromine and it has controlled her seizures.  The vet does not feel that this is related to her seizures.  At times now her legs seem to shake a little while standing - but again she is ready to jump and play.  She also has skin problems - and was treated for a yeast infection.  We just yesterday have changed her food from Purina to Innova.  She doesn't seem bothered - but we are in trying to figure out why and why all of a sudden it has happened.  We rescued this dog from a family that couldn't take care of her - 8 mos ago - so we do not have a lot of history on her.

Answer
This is kind of a complicated question, which I'm sure you know :)

I'm extremely happy you changed her food to Innova and I'd hope it was Innova EVO (high protein, low carbs, no grains).

The fact that she's "operative" during these episodes is a good sign but I'd be concerned about epilepsy and you don't say what diagnosis your vet offered re her seizures or what tests he did.

I'd like to know what the skin problems were specifically because nothing is an isolated issue.  What did the vet prescribe for her yeast issues?  Did he do a skin scrape?

The fact that this began immediately after the grooming session makes me wonder about a reaction to a shampoo? Or whatever else they may have used.

However...I'll tell you this story.  Our very first cocker (the fabulous Chester) suddenly did this "full body tremors" thing at about age two.  Of course I flew off to the vet...and another vet..then a vet neurologist.  He never (naturally) did this while being examined and I was getting the idea they thought I was this whacko owner :).  After no-one had a clue I decided to look at it as some "allergy" and on my own and (at the time) not having a clue started to do homemade dog food and totally stopped commercial.

It all stopped and never happened again.

So here's what I'd do - don't panic because she's pretty okay but I'd question the groomer re shampoo and I'd learn how to deal with yeast infections (and I can help here a LOT) and I'd change her food (which you've done.(Purina is crap).

I'd also do a big read up on her diagnosis re the seizures and see if your vet did all the right tests.  Do not assume "the Doctor is always right"...be proactive..ask questions.

Also..re her skin/yeast issues...there's a ton you can do topically to control this and quite frankly, most vets just offer meds or prescribe the wrong shampoo.  At age 3 I'd most definitely be doing a thyroid panel if my cocker had skin issues and any good vet Dermatologist would do that first.  It's common - an easy blood test - easily fixed with meds BUT the test must be sent to either Antech or Michigan State for analysis.  ASK where it's sent.  The reason is this test must be done by equilibrium dialyses and most labs don't have the delicate & expensive equipment to do this.

So just call your vet's office and ask "where do you send your thyroid testing". If the answer is wrong..keep calling around.
That's number one thing to be tested properly & eliminated.
