Dog is really allergic to fleas and has an open sore spot on shoulder blades, so would it be safe to use?
We recommend contacting a veterinarian if you have any questions or concerns in regards to your dog's health, before using Seresto Dog Flea & Tick Collar. You can also contact the manufacturer directly for product support by calling (800) 255-6826, according to the label.
