I have a 5-year old beagle/hound mix that up until last week had no problems using the back door doggy door to get into an area of my back yard that is fenced in. That is where she would do her business all well and fine. And then suddenly she started to use the carpeted areas of my home as her bathroom and refused to go into the yard. She had no problems using a different door in my house and going into other areas of my yard outside the fence (though she has to be leashed or she will take off for the woods). When I try to bring her back into the fenced in area she resists with all her might. I was wondering if perhaps she received a spook of some kind while in the fenced-in area, perhaps an encounter with a wild animal (I live up against the woods in a rural area). I even try to lure her into the fenced-in area with her favorite treat (and went so far as to use roasted turkey!) and she wanted nothing of it. She truly seems petrified of the fenced in portion of my yard, but only recently. What in the world??
