Hi, we've just picked up a new dog (a pug), he is 9 weeks old and very active. My problem is my 11 month old cavalier, for the past two days he doesn't want to eat nor drink. He always hides inside his crate or go to his bed inside our bedroom to get away from the new pup. Same thing happened to him when we had a long weekend with my relatives who have an adult toy poodle, my cav didn't eat too, but right after we got home he started eating. My concern is since the new puppy will be with us I'm afraid my cavalier will become ill. Is there anybody here experience the same thing? Please help.

Thank you in advance!
