Hi. My one year old daughter got to close to my dog well he was eating and he slapped at her. It was only a small scratch and wasn't deep at all right under her chin. We cleaned it really good and covered it up ,although she did not keep the band aid on long. Now she has a lump under the skin and it is red. It does not seem to bother her unless we poke at it. Any suggestions about what it might be or what we could do to make it better?
