Xena is a year old now. Lately, I've noticed her scratching a couple times a day. She doesn't have fleas or ticks. She's an inside dog and I would have noticed the bugs when brushing her. I have noticed a few small red spots on her back, no bumps just pink skin, not sure if that is normal.

Anyways it occurred to me today when I saw her scratching that it's always in the same place. So when I gave her a bath today I checked under her chin/muzzle where she is scratching. There is a large bump there. It looks kind of like a large bug bite I would guess but its not pink or swollen, just there. I've noticed one on her stomach a while back too when grooming her but I don't think that one bothers her.

Does anyone one know what if the pink spots are anything?
Do you know what the bumps might be? Could she have simply been bitten by something or could it be something else? I'm not sure what to do besides watch her and see if it gets worse.
Any advice would be helpful.
