So Duke has developed into an excessive licker. He licks everything. He will lick people, shoes, his bed, my bed, carpet, furniture anything and everything. If I tell him enough as this can become extreamly annoying he will just lick something else but be 10 times more focused than he was before. He has been doing this for a while but it just seems to be becoming worse over the weeks. Is there something wrong with him? Why does he do this any ideas? I read somewhere that some dogs can have OCD, could this be it? He will chase his tail every now and then but I stop that right away because I also read that thats not good for them to do. Any input would be wonderful.
