Hi everyone. Gracie is 6 years old and about a month ago I noticed she had rust colored stains on each side of her lower jaw. I tried washing with soap and water but it didn't come off. I took her to the vet who suggested it might be her dishes (ceramic) leeching nasty stuff into her water. She gave me some Mal-A-Ket anti-fungal pads to wipe her mouth after she eats and I switched to stainless steel bowls. Two weeks later it doesn't look any better.
Has anyone else run into this problem with their Corgi? I also noticed darker color staining on her private bits. Any advice would be appreciated. Maybe switch to bottled water?
