I have had a border collie mix, (maybe Scotty like the breeder said but I
don't see anything but border collie) since early November, he was born Sept
3 so he's almost 6 mos. Anyway, he has been taking to training pretty well
so far, sit, stay, lie down, come, shake, housebroken, rings a bell to go
out, and sleeps and rests in his cage. He has been very friendly with the
adults we meet on walks so far and with my 8 year old daughter who feeds and
plays with him. Today however, he started barking at the kids playing while
we were walking past, and the mother of a 3 yr. old came out and asked if
the child could pet him, I said he has been very good till now, but as the
child got closer (she was crying to pet him when we first saw her and was
still making a racket while reaching out) but my pup got very aggressive and
the fur on his neck was standing up while he was barking and even tried
nipping the girl. He was fine with the mom, just sniffed her, but the way he
acted with the child has me worried, any advise would be appreciated. I'm
gonna get him neutered as soon as possible hoping this may calm him a bit.
