My 19 month old black lab rescue mix female WILL NOT STOP LICKING my other 2 black lab rescue female and male 5 yr. old dogs. She licks their faces and mouths constantly and they hate it!
Help! How can I stop Lucy from licking the other 2 dogs. (2 older dogs are not related).

I don't know but my younger dog grooms my older dog and the older dog HATES it - so my younger dog pins her down and then licks her face. It's some sort of pack mentality grooming thing, I think.
