Nails Saliva Staining Dog. While it’s harmless for the most part, there are some medical conditions that could cause excessive staining in your dog’s fur. High temp is going to set the stain (e.g., coagulates proteins, blood saliva gets meshed with fabric fibers making it very difficult to impossible to remove without damaging the fabric).
Spray the solution onto fabrics and let it sit for 15 minutes, then wipe it off with a damp cloth. The whitening shampoo helped a bit but it pretty much j6st needed to grow out. Upon heating the stain, it adheres to the fabric fibers due to its intense heat.
