Steroids are a group of medicines that help with a range of conditions in pets. They are most commonly used for reducing inflammation and managing the immune system.
Pets can get sunburnt just like people, especially if they are light coloured or have a thin/patchy coat. Sunburn is painful, causes skin damage, and can lead to certain types of skin cancer.
Very minor wounds (cuts, grazes, burns, bites and bruises) often heal themselves. More serious wounds should always been seen by a vet.
