Thanks for using Petco Pet Education Center, formerly Petcoach! This is concerning as the wounds are large and extensive. I would be concerned that this could be some form of immune mediated disease or a reaction to something in the environment or medication or perhaps an infection of some sort. I recommend that you have Bella evaluated by your veterinarian for further assessment and treatment. They would be able to check for these possibilities and treat accordingly. Diagnostics will likely include infectious disease testing and a skin biopsy. Good luck and have a great day!
