He is just over a year old and it's not a HUGE problem but he has one particular hole he is particularly fond of which, when he's digging in it you can only see his hind legs and tail.
(and it's at the root of a very lovely dwarf maple tree)
Now the better weather is here I have filled the holes, and spent much of last weekend out in the garden with him, - he had a go a couple of times, which I put him straight and he seemed to understand. Then I noticed he'd started on a new one under the trampolene.
But yesterday when my back was turned he's dug up his favourite hole, and because it's been raining again has made quick and light work of getting shoulder deep in it. I caught him in the act and as soon as I called his name he lay down flat looking guilty - so he seems to know it's wrong but just can't resist it.
Any tips on training or deterrents, citronella any good?
Help, please and thanks.
