Yes my Toby, i don't you about but I figured he has worms because he didn't get is second deworming done. We are giving liquid med for roundworms. I don't know if he has roundworms or not, it might me tapeworms and if it is then he would have to get an injection to get rid of the tapeworms. My Toby fur is dull looking, is that because he might have tapeworms.
