Shaking and tucking tail.

3 days ago my dog, who was being taken on a walk in the morning, suddenly started shaking, acted confused and tucked his tail and tried to hide. We soothed him and the trembling subsided but he was still confused. Every day since, he does his morning walk without incident but when he comes home, he seems afraid, tries to hide under objects, is fidgety, won't drink or relax until I sit with him and even then it's temporary. He's a inside dog and has had no trauma. We suspect a small TIA but don't how to determine the next course of action. The nearest Catscan or MRI is 175 miles away. What to do and will he get better with time?

He sees a vet regularly and is current on all his meds and tests. However, we have not taken him to a vet for this attack because there is nothing that can be done for the wierd behavior he is exhibiting. It's not the shivering that bothers us and his back is fine , he's not in pain. We pet and rub him constantly and he shows no signs of back trouble. He eats and eliminates well and sleeps well once he gets relaxed. It's the appearance of fright and cowaring that is most severe. The dazed and confused stance he takes. The need to be coaxed to follow. With all that said, h woke up this morning after an 8 hr. sleep and was alert and normal. We live in Florida and walk him on the beach and he will be great at the beginning of the walk and when he returns home, reverts to the hidding, confused, uncooperative,dazed yazzi. As if he's forgotten what to do next. Again, let me repeat that this just came on with no warning leaves and returns just as quickly. If no pain, what else could cause this behavior?

Thanks for your promptness and insight. We have found a condition that explains the symptoms and we have scheduled an appointment for a check to see if it is what we think it is. The problem we have constantly is that most vets around here have never seen,treated or studied standard Poodles and they are unique in a lot of ways from the dogs they see.
As described in the text we've found it seems to mimic Idiopathic Fear and Withdrawal. A condition which is genetic in the breed and is often brought on with age. Apparently the autonomic nervous system is affected causing these episodes and they can be controlled with the anti anxiety medicine you mentioned. With the vet visit and bloodwork, we can hopefully rule out brain or thyroid problems and possible toxic substances.
To let you know what happened this morning, we took him on his walk and half way through he reverted to the confused and fearful stage. He is just now calming down but still insists on staying within 1 foot of me at all times. I am still sure that there is little or no pain involved but the vet will hopefully find the causes.

Dr. Marie, just a followup on Yazzi. I took him to the vet this morning and I want you to know that you were spot on. His anal glands were overwhemingly full with what can only be described as a huge volume of dark matter. It was the worst the vet had seen. She also recognized an apparent pain in his spine for which she prescribed some pain medicine and stated that it possibly was from the gland condition. We brought him home with the promise that in 2-3 days we would return for the senior blood work up and Xrays. He is already better acting and has not reverted to his withdrawal mode as of yet.
I will sing your praises and direct all who ask for guidance or information to your web site. Thank you again Leon W
