Dear Customer (name blocked for privacy),
I am going to need a bit more info from you about the "scar" that your pet has. Is it an old scar that has healed well, or a constant open wound? What does it look like? Is it a large lump? What is the discharge like? Is your pet running a fever? Eating and drinking ok? Please let me know so that I may help you further. If you have answered yes to any of the above, please call your local vet, you pet will need antibiotics and also may need the wound flushed with a Chlorhexidine solution. Thanks
Mickey Du Bois
