PLEASE HELP!!

Hi elev8 my dog hooch keeps digging holes in the garden.  My Mum is getting really angry so I have to cover up for him by saying my sister got a shovel and was showing off to her
friends and dug a hole. She did once but please help I can't keep it up any longer. PLEASE HELP!! 



Digging problems: The most pet-friendly garden solution here is to consider giving an unrepentant canine digger  a digging pit. Dig in to the ground a plastic container no smaller than a washing up bowl and fill it with fine sand. On the surface of the sand place favourite toys or pieces of food. Encourage your dog to look there and reward when he goes to the pit. Now you can begin to half bury the toys etc. and make the dog dig out these toys. Once the dog ha learnt this then you can  fully bury his belongings  in the sand; why would your dog wish to dig in hard clay and find nothing when it can dig in soft sand and be guaranteed to find something ?
