My dog has an itchy bump on her side with pus. What should I do?
It's difficult to tell exactly what's going on here without seeing the lesion and being able to do some testing, but I am suspicious of a skin infections. These infections can be due to fungi, bacteria, parasites, or all of the above. There is often a primary problem that causes the itch, so if Maggie has been itching for a while, then it's best to get the source of the itch discovered by a vet.
I'll give you a few tips for dealing with a skin infection, but if the lesion gets worse, or is not getting any better within a week of treatment, then I'd recommend you have a vet evaluate Maggie.
I recommend doing the following every day until the skin appears normal again:
1) Clip the hair around the area and expose all of the lesions.
2) Wash the area with warm water and a medicated shampoo (can get this at the pet store) once a day. Use a cloth and gently wipe away the scabs. Do not scrub, because it will irritate the skin more. It's OK if all of the scabs do not come off in each washing.
3) Make sure the area is completely dry after washing.
I hope that helps and all is well with Maggie.
