Review on 🐶 Covono Electric Dog Fence: Versatile 650 Ft Wire, IP66 Waterproof Collar for Reliable Pet Containment by Stacy Sturm

I have a german shepherd and the first use with it went well, we walked around the yard and when she approached she squeaked and she came back switched off. The next day I got her out, put the collar in the same place as before and he immediately started squeaking and shocking my dog, now he's afraid to go in the backyard and just runs forward. She's had accidents around the house (which isn't normal for her) because she doesn't go into the backyard. I'm very upset, it's a new house with land and she actually has plenty of room to work, but now it won't.
