We have 6 acres of land here. The back 4 from the house back are fenced. We will soon be refencing it as the fence I put up this summer is not working well. Tavarish (the doberman) was told to not go over the fence. I never thought about telling him to not go under or though the fence. Who knew he was such a technical dog! So he pushes his way under or through (at the posts). The fence is a plastic fence. Tavarish taught Jet how to get out too. I had to let her in the front door the other day. We went to talk to the neighbors about us putting up a new fence soon and he said he saw both our dogs playing in his yard. Great. Yeah, well, the ducks go UNDER the fence too and make their way to the side and front of the house. Bad. Dogs and other things out there. This morning, as I'm putting food down for the ducks I hear them running and flapping their wings. I look up and see Ally flying herself along about 2-3' off the ground for a good 20+ feet!. great, next she'll be flying OVER the fence. So, we have 4 acres of perfectly good back yard and nobody wants to stay in it! we have to remove all the posts and remove the fence I put up this summer and have a guy come in with his forestry mower and clear the rest of the property line (I cleared it by hand wide enough for me to get down it with rolls of fencing - now it will be a 4-5' wide path). Then we'll put the posts back in - nice and straight since we'll be able to see from front to back of the property - and put up a nice new field fencing to keep dogs and ducks in. As long as nobody decides to figure out their way OVER that fence. Or through. Or who knows. But they better stay in the yard! And we'll add another string of barbed wire to the other neighbors fence so neither dog will be scooting under that.
