hi, im new i am currently 14 years old turning 15. I have a 5 month old border collie pup called zoey. She is black and white with the pure markings shes also very smart, but there one thing that has been making our family get rid her. She will not stop pulling the cloths off the line. We have tried sprinking black pepper around the cloths line but that didnt help is there any other ways that we csan stop her?
