I have just notice after picking up my dog from my parents house that Maddy has block spots on her feet and legs? I treat her for parasites with frontline and after I bathed her today I noticed that she has these really strange dirt like material around her feet. I don't have a clue what this could be?? I have seen fleas and completely know what they look like but this doesn't look like that just black spots adhered to her feet???I would have seen jumping fleas if she would had these right?? Especially in her groin and back areas correct? I have resently treated her for parasites I put it on her on last Wednesday?


Any suggestions? I am just freaking out because I have 4 cats also and I don't want them to get infested if that is what they are?
