Baby girl is arriving in a week and a day (very excited!). This is my first dog and I obviously want to do everything right. How soon is too soon to introduce her to 'scary' loud sounds like a vacuum and hairdryer? I want her to be tolerant of these sounds as I plan to blowdry her hair after baths etc. But I also don't want to give her any scary formative experiences! Advice would be very appreciated! Also any other advice on what I might not be aware of as a first time dog owner would be too!
