Hot Spot Remedies

My Black Lab developed 2 hotspots on her belly after we got her spayed. I used a dry antiseptic powder (over the counter brand) which I applied approximately 3 times a day. After a few days of this I then dabbed sea salt and water solution on with cotton wool before I applied the powder. I used the sea salt solution approximately 3 times a day and the powder approximately 3 times a day. After 2 weeks she was completely free of hot spots. It is obviously highly important to the healing process to stop the dog licking the area as much as possible. Best regards
