Two of my pigs had a fight last week and couldn't find any obvious injuries to start with but seperated them. Over the days one has been more subdued and tonight he has started licking and licking at his shoulder. On closer inspection I've now found a pus filled hole which doesn't smell too good. Have cleaned out with warm salt water and have some Dermisol healing cream I could put on but am worried it says horses sheep and cats on tube but not piggies! Also should I go shop and get tcp or just stick with the salt water? Obviously I will get him to vet first thing Monday morning but just need best solution till they open?
