My pup is 1 year old. She has a pea sized red blister looking thing that grew recently on her belly. It was soft at first and is harder now. It doesn’t not seem to bother her. Do I need to go to my vet or wait a few weeks and see if it goes away?

That is most likely a histiocytoma: https://www.veterinarypartner.com/Content.plx?P=A&S=0&C=0&A=1676 It could also be a cyst or a plugged hair follicle. It is hard to say just by looking at the photo. My recommendation would be to take her to your vet to have it checked. If it is a histiocytoma it may go away on it's own within a few weeks to months. Hope this helps.
