hi well not many people are in the same boat :) honestly i have no idea!the only things i can think off our how far is she digging the chicken wire into the ground go as far as she can with it further than 12inches because a rabbit can dig further than 12 inches . if she looks at the garden before she lets the dogs out and spots a whole if she can tell her to go out and put like a fence around the whole until she has time to fill it. by a fence i mean make like a square 4 longish sticks and put them in the ground surrounding the hole one at each corner and then use duck-tape and tape all the sticks making a square use basic sense if she has a small dog put the tape quite low down about shoulder height to the dog and vice versa for a big dog no idea about fox urine but you can get certain sprays which are meant to keep out rabbits non-toxic but you might want to not let the dogs go out as soon as it's been put down look in the supermarket or on ebay for such stuff.
