I would like to hear your opinion. So, I have a 3-month old pup, she just had her 3rd vaccine today and in a week we'll finally start going for walks So the question is, is it better to use a harness or a regular collar? My first reaction was to use a harness because it doesn't put any strain on the neck, plus I used it for my first dog. However, a collar might be more useful for training. So, what are your experiences/opinions? Any input is quite welcome
