My 2 year old male yorkie MAX will just be sleeping then jump up and look at me and then he will go to walk and he can't move his legs and starts to shake and then he looks at me, but he is like looking right through me as if he can't see. He brings is front paws up like he is trying to make fists and his toe nails are tight. It last about 4-6 minuets and then he goes back to himself. He is going to the vet tomorrow but I just wondered if anyone has had this happen to their puppy power. He is my sugar bear and I love this little bubba sooo much. I am so scared. Any info would be greatly appreciated.
