My dogs are 8 months and 5 1/2 months. They play very well with my mom's two italian greyhounds and love being around them. My question is, if I'm out on a walk is it normal for them to pull towards other dogs and bark? Does that signal any kind of fear or DA? Emma will pull her way towards the other dog and bark until she gets close up then she'll start hopping around the other dog. Bentley does the same sort of thing.. zooming around the other dog and barking. Is this play or is it something that I should be worried about??
