Red bump on puppy

Does anyone know what this is it’s on my puppy’s belly near her nipple and she scratches at it and makes it bleed

Hello!  One thing I do know about this is that it needs a vet appointment, because scratching will damage the skin and tissue on and around it, leading to pain and infection, leading to more scratching..... And indeed, the longer they are left, the secondary effects of such lesions become worse and harder to heal. However, you asked what it is.   Possibilities include: an extra nipple, got infected; a tumour (got infected; they don't usually itch); a histiocytoma (strawberry lump); possibly a hernia (doesn't look like one from this angle?); an exaggerated reaction eg to a fly bite or foreign body..... It is likely that your vet may not know for definite on the first presentation, but this is ok - they will help to formulate a plan as to what to do next.  Best of luck and please do report back as to what happens!

NB having read that back, it reads a bit doom-and-gloomy in that tissue damage can occur more quickly in some animals than others and not all lesions will become badly infected extremely quickly (although some will); rather, this is something that should be examined because protection may be needed against it.  Bleeding shows that the superficial (protective layer) of cells has been affected.  Strawberry lumps appear and disappear again sometimes on their own accord, but not all lumps do, hence the possible need to have it checked out.  Strawberry lumps also don't usually itch, but sometimes the very location of a lump can be enough to stimulate licking.  Best of luck.

I’m having the exact problem with my dog. Did you find out what the problem was? We’ve made a vet appointment!
