When you return home after being out in the snow check that your Irish doesn’t have snow balls attached to his fur.  If he has, then use warm water or a hairdryer to melt them otherwise they will make a mess and he will probably try to remove them himself and chew his fur as well.

These are only very small snow balls but they can get considerably larger. 

If he has been walking on salted or gritted pavements then it is a good idea to clean his feet by putting them in a bowl of warm water to stop any irritation.  If the temperature is well below freezing then it is not a good idea to leave a metal water bowl outside as his tongue could stick to it.

Finally make sure the oldies and youngsters don't get too wet and cold.

Most importantly take your camera with you to capture the moments of sheer delight and fun.
