Both my dogs appear to have colds (or at least the canine equivalent). They are constantly sneezing and have increased 'sleep' in their eyes. Does anyone have any tips on how to treat this? Also, one of them is due their booster vaccination - I am thinking it would be advisable to wait until they have got over their cold. Will the insurance company mind if it is not done on time?

I think a trip to the vet would be the sensible course of action. As one is due for a booster anyway you can get them both checked and the vaccination given if the vet decides it is appropriate.
