My dog recently started licking everything. He licks the sofa, the bed, our skin, the carpet. We have had him for 8 years and he has always been the perfect dog. We are just curious.
Just for your info, he recently had a check up and was diagnosed with heart murmur, and also never urinated in the house, but recently did a couple of times. I do not notice that he is drinking more water and he is eating OK.
