I tried one of those jean,he got it tangled with shrubbs etc,now just a long lead,the wall between my house and next door is less tha 2 foot in hight,being on the corner a long low wall between the house on my left,they dont like dogs sure the dog knows as he always barks,after of of the children tried to hit him,why do people buy or rent a house where there are lots of dogs,if you bring your children up to think dog are dirty,
