Really worried about my pup 
He had his 2nd jabs yesterday, vet said he might be a bit sleepy for the rest of the day, he was a little but all in all he was his normal self. He has been a bit sleepy today but about an hour ago i noticed one of his eyes was closed, i thought the cat had scratched him as they had a run in, now he's gone very sleepy, i can hardy wake him and his other eye will ony half open (the other is still closed). Is this a reaction to the jabs or should i be worried? he has been in and out of the vets last week after having colitis
. Do i need to call the vet and get him seen?
