Oscar has been like that, but he has also started sneezing. The vet has given him some eye drops, which have cleared up the eyes, but he is still sneezing in the house. He has been fine when we are out; we are checking a few things. We have a lot of those plug in smelly things as we are trying to sell our house and we do not want it to smell doggy. We have unplugged all of them and his sneezing seems to be getting better, so we will have to keep an eye on things.
