Any lumps/bumps that you notice on your pet should be checked out by your vet. Lumps in this location can be any of these things: * abscess (infection) * cyst * cancer (benign or malignant) * rodent ulcer I suggest you find a vet to take him to for an examination. There are no home treatments for any of these possibilities. Also, treatment depends on what the lump is - all those possibilities have different treatments.

This could be a temporary inflammatory reaction -0 either to trauma or contact irritation. If he is otherwise well and is not in pain I would wait 72hours to see if it starts to dry up and reduce in size. If it is increasing or still moist at this stage then a vet check would be recommended

Without a picture it's difficult to guess, but lip swelling can be a rodent ulcer, which is usually due to an allergy. Make sure Leonardo is on flea prevention and you can also try switching his water and food bowls to a different material. If it doesn't go away you should see a vet as he may need further treatment.
