I usually use vaseline. Ulysses has a tendency to have a very very dry nose during the winter. He licks it off like crazy, but it's so sticky that it still helps. I have noticed though that sometimes he gets a little diarrhoea afterwards. I'm not 100% sure they are connected, he also gets loose stools when we go for walks in town, I guess due to over excitement or stress of being surrounded by lots of people. Anyways the vaseline works great for us, but I'm definitely gonna try some of the stuff other bully parents mentioned here .
