Barking at neighbours dog
From the very start my 6 month old -Pixie, has been barking at the neighbours dog.
The neighbours back garden backs onto my back garden with a slotted wooden fence separating, so if she is out at the toilet and the other dog gets let out the back she either hears or sees through the slots or smells this dog and starts barking / growling.
I remove her from the situation straight away by rattling her food dish and she comes inside, her recall is low at this point.
Is this a sign of needing socialization? I'm taking her to puppy classes soon..
