Hi, I have two Schnoodles, brothers by the names Buddy and Samson (age 3). Buddy loves to dig, whilst Samson does not. They get walked twice daily. Given toys, bones etc.
My lawn is now at a stage where there are so many holes everywhere my children cannot run around in it. I keep backfilling and it just gets worse

It is a large back garden that runs down to a reserve at the rear. People walk their dogs along the path at the rear so I do not want to restrict my dogs accessing the rear boundary to socialise. Any ideas for a practical solution are much appreciated. The other issue is that the inside of the house is getting a build up of dirt from his paws. And now vet bills for wheat grass injury and dermatitis on his paw. Help!
