Three nights back my little Border Collie 8 years old had a vicious fit at just gone midnight.Back arched and spinning wildly on the floor.I held him for nearly five minutes until it subsided. It was his first and it has not recurred...The vet checked him out...heart,lungs,bowel etc (All ok)and took blood samples which will hopefully return tomorrow from the lab. 24 hours later I took him to another vet who checked him again and gave a pain killer injection in case he had sprained something in the fit. The second vet and this post is because of his behaviour since.I can understand him being in shock and unsteady for a while but the little lad has completely changed.From a normal boisterous dog like his brother into a nervous wreck. He stays in his bed all day...when I call his name I get a little flick of his tail,but he stays in his bed. If I call him to me he sometimes won't move...and if he does come he approaches me as If I was going to give him a beating head inches off the floor and tail between his legs.I lift his head and make a fuss but as soon as I let him go he goes straight back to bed. In the mornings he shows more interest and trots to the gate for the regular morning run in the woods with his brother.I was pleased this morning when he picked a stick up and showed a little more interest in wanting to play.But the bounce just wasn't there.After the run we returned home and he went straight to his bed and stayed there most of the day. He's eating fine,all in one go as usual. But he's just not the playful little dog I had three days ago...hopefully the blood test might explain something tomorrow and the fit might be a one off (I hope)...but what I want to know is has anyone else had a dog who's personality has completely changed after a fit...and if it has have they eventually returned to normal...he's such a sad little dog...but with a good appetite.
