My two month old pug puppy is having seizures.Please help

[Roshni_s]

I bought Pogo from a pet shop.He was absolutely fine and very active in the beginning.One day I discovered that he was unable to get up and stand on his feet.i immediately took him to the vet who told me that it is due to weakness.Although he eats properly,he still is unable to get up n walk firmly.The vet also told me that he is anemic and has given multi vitamins and glucose to drink,but still he gets seizure attack any time in the day.His legs become stiff and eyes pop out,all I can do is keep rubbing my hand all over his body just to make him feel that I am with him.Please suggest me what I should do as Pogo is just two months old and I am unable to understand the cause of his sickness.
