|Small pea sized lumps can be any number of masses:
Benign (IE NOT CANCER) options include:
lipomas, cysts, sebaceous gland adenomas, papillomas and hives (although with hives you usually see more of them **BAMA this could this be your issue - I will stop by your thread next**)
Mast Cell Tumor (these can start very small and are refered to as the great disguising mass since they can feel just like lipomas - a FNA (FNA -Fine Needle Aspirate Test) will succesfully diagnose these HOWEVER if it is really small they may wait to test until it gets bigger as an adequate sample can be tough to optain on smaller masses, melanomas (although they are usually black in color - sometimes these can also be benign), Fibrosarcomas (usually isolated and don't metastize well), squamous cell carcinomas (although these usually occur on unpigmented or lighter colored areas and you are a black dog so really doesn't fit but they also are pretty localized but can start destroying the skin surrounding and cause a large lesion if not removed),
This is a good link to start with but a vet visit is highly reccomended anytime a new mass is noted. Skin growth-lump-swelling-mass in dogs INFO
Has he recieved any injections or vaccines recently? These can somtimes leave small inflammatory lumps (rice sized/pea sized) under the skin which are not dangerous but can take up to 6-8 weeks to dissapear and should be mentioned at next vet visit even if they are still not present as they may want to avoid that injection in the future.
Hope this helps
ETA: Marking the spot of the mass by either shaving a small bit of hair over it or using white out or permanant marker (harder on black fur) will help you monitor the mass, you can measure its diameter and height in mm to see if its growing and how fast, the marking it helps in case it dissapears or you are having trouble finding it again (or at vet) the mark will always be there to make sure you don't go crazy if it disappears and you can't find it!
