well he seems to be feeling much better
he was so full of energy last night when i got home that i took him on a 15min walk round the block...but he was still very restless and wanted to play all night so i think he's definitely feeling better! (he normally gets 10min walk + 45min in the off lead park...lots of energy to burn!) i didn't want to expose him to too much stuff so just let him run around the back yard and in the house
he ate around 2/3 of his dinner too last night and this morning had a semi-hard poo so i think we are definitely past the worst of it!
thanks for everyone who posted...it's been a very long 3 days!!
