I just fill them in again,replant the plants,fingers crossed they will survive :D
The first couple of 'digs' were quite small but now Spice has progressed to what we call 'bear pits'

We just keep several towels near the door now,to clean off her paws.
On the whole the garden is 'safe' all dog friendly plants etc. and at least whilst she is digging she is not pruning the roses!
