This is my first post. I was so happy to find this forum. My Lilly was 1 in February and is a very active little girl. We want to protect her with a fence however I am a first time doodle owner and am not sure of some of the traits. Are Doodle's jumpers? Should I use a fence higher then the standard 4 foot model? Second question, we considered invisible fence, but I am a bit apprehensive. I guess I don’t trust anything I can’t see. It seems to work for others in the neighborhood, but I’m afraid she will get through it. Any thoughts or suggestions from the seasoned Doodle parents would be appreciated.
