Jake, our 10 1/2 year old black lab has become a bark machine. He seems to be barking at everything lately--even when there is nothing to bark at--no people on the street, no traffic, no squirrels,rabbits, chipmunks etc. We try to not react to his barking--but of course that does not always happen! I do not want our 22 month old Golden retriever to develop bad habits! We praise them when they bark because someone is there or a car drives by. Any suggestions would be appreciated.
