Today I noticed my Daschund licking the inside of his front left leg. When I looked I noticed what seems to be a scab or cut of some sort and he growls at me when I attempt to see it. Thought I should mention that he recently hurt this same leg during a walk, but that does not seem to be bothering him anymore. Another thing to mention is that I have always really noticed him licking, just never thought anything of it. I am pretty worried it is something serious.
