Any suggestions (besides getting rid of her) of what to do? Are there any dog repellents that might work?

I put up a temp fence in an area that is about 100 sqft. Where I am renovating but the other areas are too small.

1. Seeking your attention.
2. Bored because he does not know what his job is.
3. Trying to escape.
4. Fresh turned dirt because decaying organic matter and fertilizer is a natural attractant to dogs.
5. Digging a den, especially pregnant females.
6. To cool or warm themselves.
7. Terriers and Labradors instinctively are diggers.
8. They are hunting.
9. Disposing of food or digging hidden food up.

Sounds like you are #4. Only way to correct it is with consistent negative feedback like whenever your dog starts to dig, spray him with the hose, or swat them on the hind quarters with a rolled up newspaper with a very negative aggressive NO tone in your voice.

Think those green seed covers might help? The biodegradable ones? I have some left over from last year.

My solution was to buy some chicken wire fence (The kind with the little wire octagons) and spread it over the area where the dog lived. I carefully staked it down so the stakes did not interfere with the mower. Once the chicken wire fencing was in place I covered it with about an inch of dirt and planted grass on it. The dog stopped digging in the yard.

I have often wonder what the new owner thought if he tried to plant bushes in that area.
