Ok, so I have got the ok to fence in an area for my new gal Butters and her soon to be buddy. Thing is I only have about 100 bucks to spend on fencing (not a lot). Does anyone have experience with the fidoshock or the haveaheart dog fencing? Because I can afford either of these. I was looking at larger animal fencing and it is really expensive.....so does anyone know if the dog fencing will be strong enough?
