I have a seven month old puppy, on saturday he had a medium sized swelling come up on the bridge of his nose. The swelling has now gone down, but it is very very itchy. I don't know what happened to it but i would hedge my bets on the cat swiping him one. There is no obvious open wound and no sign of infection.
What can i put on it over night to help him to stop rubbing it on everything, as i don't want it to become really sore and possibly infected.
TIA
