hi guys, its been a while, im a little confused, i have sbt, they have been having a play fight, all 3 bitches, (you know what theyre like), when i looked at one of them she has lots of tiny little lumps, it looks weird, infact my skin is crawling when i look at it, we had her to the vets last monday, as her 2 eyebrows swelled up, from what i now assume was the same thing, can nipping cause a reaction, because they were all playing just the same and only one of them has these lumps,

thanks
