I have a 12 week old english bulldog pup who goes crazy howling, barking and crying when we leave him alone. We have to go to work, but when we are home in the morning and evening and weekend he is always with us. We have only left him for 2 days so far, and our neighbors said the second day was a bit better than the first. Will he get better? Is there something we can do? It's not possible for me to get home during the day.
