We've a lovely pointer who is 1.5 years, and a 3 month old baby. The dog has taken to the baby better than we could have hoped for, but recently she's started to become embarrassingly barky when strangers either knock on the door, or walk past our 'space' outside, meaning wherever we're sitting. She's fine when we're just out walking as usual though. This is now happening whether the baby is with us or not.
Any ideas of how to make her less defensive? She used to be really good with everyone!
