Thank you.
It would be ideal to see a vet if the lumps are growing and spreading. This could be something as minor as warts (which aren't transmissible to people and typically self-limiting) to mast cell tumors. For good measure, I would suggest cleaning the areas 2x daily with saline, patting dry gently and dabbing on regular Neosporin (not the variety with pain relief). Avoid bedding that might stick to the area. You can purchase an OTC saline solution or make your own at home by combining one cup of boiling tap water to 1 tbsp of table salt. Dissolve and allow to come to room temp before using.
