My Dog Developed A Lump And Now It Pop Open Leaving A Hole... What Do I Do?

What kind of cream would be best to put on a popped cyst, on the left hip of our family dog? I keep it clean with peroxide, and saline wash, but it still looks bad. I really can not afford a vet, but don't want our dog to die or get worst,

Please help, thanks

My cat's get them all the time. Ive heard it could have been a minor snake bite or a cyst that popped. Just keep cleaning it out with saline and keep it clean.

The best thing you can do is wait and if that doesent work you should proboy take your dog to a vets office

Like you say, may have been bite, or another is a very bad cyst. Seeing as you can see so  much, as it seems to go quite deep, a topical antibiotic is still needed if animal is not suffering. Any exposure could allow infection to get it. As well, I would not hesitate to have animal checked by a vet seeing as you don't know where it originated
