Digging! How to stop it?

[Charlie]

Hi, we've two young Dachsies - 16 months old - and they are destroying the garden! They have dug any number of holes.
It's not always clear what they're agter, at first I assumed they were trying to dig up snails, but they've also destroyed a flower bed where they seem to be after the roots of plants.
Can anyone recommend an effective, but safe, deterrent?
I don't fancy using pepper powder, for example, in case it gets in their eyes. But there must be something that works - any ideas?
Thanks in advance for any help on this!

Dachshunds dig. It's kind of what they do. They only thing I've found to keep them from destroying my garden is to watch them carefully. I had one that loved to dig. We finally reached an agreement that if he only dug under the split leaf philodendren, I'd leave him alone. Eventually, he stopped even than.

I also had one larger mix who was 6 months when I adopted him. He dug up the whole backyard before he stopped. It sort of looked like a moonscape out there. The good news was we didn't have to mow often!
