Well, Callie has to have a remote collar, much as I hate it! She just doesn't seem to listen when she sees a rabbit, squirrel, deer, cat, or mouse, or anything, lol! Anyway, we've had it for a couple of months, and when we go for walks, she has to wear it, as we live surrounded by farm land, and woods! Today, we went out through the fields, and she saw a rabbit! Since I mostly only ever use the tone to get her to listen, it didn't work today, so I tried the lowest shock! Nothing! I didn't have it around her neck tight enough! Oh, great! Off through the woods she went, with me screaming my lungs out! Finally, she decides to come back, and somehow ends up in a sheep pasture, surrounded by fence. Meanwhile, her mommy, who broke a rib two weeks ago, has to climb up over the metal gates, two of them because they are padlocked, to go in and retrieve the muddy and sheep poopy dog! I had to lift her up and over, hang her down as far as I could,and drop her to get her out, twice! Needless to say, we came home and took a bath, lol! I was NOT in a very good mood!
