My elderly neighbour is really ill at the moment, so I have offered to walk her dog a couple of times a week to help her out. She told me she can't afford a dog walker, and doesn't have anyone else around to help with the dog and was really grateful for my offer.
I've noticed the dog has red, scabby /scaly patches behind the ears, and the fur behind the ears has fallen out. He also has scabs on his face, and a few on his legs, and what looks like a cut beside his eye. One of his eyes is bright red also. Does this sound like mange? Or could it be something else? I really want to help, but I don't want to offend my neighbour by bringing it up, as I have no idea if she has already spoken to the vets about this. I'm assuming she hasn't because she has been too weak to leave the house for a few months. I want to say something along the lines of 'would you like me to take the dog to the vets about his skin condition for you?' but I don't want to come across as nosy/ interfering. Should I just go ahead and ask or mind my own business?
