My friend bought a chihuaha a while ago while on vacation. During the vacation the chi would follow them everywhere she got along well with everyone they met. She never barked or squealed.
Now, the chihuahua always barks and squeals at everyone she sees whenever they take trips with her. But when she's at home, she's very relaxed and usually doesn't bark at people.
Can someone help us with this problem? Thank you very much
