New Born Pup
So, a few weeks ago I noticed a lump in my guinea pig Marshmallows back. I shrugged it off bit a few days later I came home and it was gone and replaced by 2 open wounds, they looked sort of similar to a spider bite but spiders are not common in my area. Blood was leaking all over her white fur so I gave her a salt water bath as I didn't have any disinfectant on hand. Every time it starts to heal she just picks it off. How do I stop her picking it and also what is this wound? Is it a spider bite, has she just scratched herself or what?
