The OH was just stroking Jas and said he could feel a lump on her back

I've just had a look and it feels more like a 'swelling' than a lump and weirdly enough it seems to be in exactly the spot that she had her booster vaccination last week

As she was being frontlined as well the vet injected her slightly lower down than usual so it wouldn't be the same spot as the frontline

I've tried to have a look under the fur and can't see anything as I was thinking maybe she's been injured outside or Meg might have bitten her when they're playing and it's an abcess but I can't see a thing

Just wondering if anyone has heard of a lump developing after a booster as it does seem to be in roughly the same spot which seems an odd coincidence to me
