I had a Yorkie, Oscar, for 13 years...He started doing the same thing when he was about 4-5 years old. I am a nurse and the whole episode appeared to me to be something like a seizure....except for the part where he could respond and walk "drunk". My greyhound, who normally didn't give Oscar a second look, could tell when he was going to have a "spell" and would start following him around and licking on his back.  
 There were times Oscar would have these spells every 2 months or so and then he would take a time that he only had 2 or 3 all year. 
  The vet felt like they were some sort of seizure activity but hesitated using any type of seizure meds unless they started happening monthly or more. 
As I observed Oscar more I noticed his abdomen always felt tight and bloated when this happened. I began to notice they DID happen more often if we over-indulged him with table foods/treats. I don't mean one snack/scrap and the spell would happen...but times that we wre giving him too much good stuff ....after a week or so it would happen again.   
Do take him to the vet....I'm curious what he thinks may be going on.   
P.S. When I mentioned it to a "fill-in" vet she said it sounded like "gas-attack" from table food.......I think I laughed under my breath and never saw her again. I'm pretty good at knowing the difference between gas and a seizure.     |
