I'm sorry Igotalife to have offended you. I didn't realize that high frequency collars are different than those that shock. I've never had a dog so I've only read about the ones that are hurtful. (since gabriel is a cat person, he misunderstood as well).
I also should have clarified my wording of behavior modification. With respect to my kitty, I would make she sure knew when I was leaving and returning home, thinking it wouldn't stress her out. But that however, was exactly what it was doing. I had to modify my behavior and just come and go without making a big deal about it. That hasn't happened with my other kitties. Just Snowflake.
So I guess I just thought that maybe when Homie saw you leave to go on the other side of the fence, he was thinking you may not come back, and that's why he was crawling over the fence. He was getting anxious about separating from you.
Please accept my sincere apologies. You are very kind to take Homie in to your Home and your heart.
