Thank you for using Petco Pet Education Center, formerly Petcoach! While this may be a bug bite, the texture appears slightly rough in the photo, so this may be a growth or mass. It is concerning that is has been present for a week, as a bug bite would have likely resolved by now. I recommend having Layla seen by a vet as soon as possible, especially because the area is red and near the mammary chain. Your vet can either remove the lump or take a small sample to determine exactly what it is. I hope this helps and that all is well!
