Background: We have two dogs: One is a Springer Spaniel and runs nearly all day, and for the year she was our only dog, we had no yard problems. We were able to keep a nice yard with lush grass, flowers, plants, even a small veggie garden. Now we have a second dog: she's a boxer mix and is not as active as the first, but has completely torn up our yard. We got her as a pup, trained her the same way as the first, but have had very different results. She's about two years old now, and has eaten all the rose bushes, ate all the veggies (no longer have a garden) and has a huge digging problem. Once she learned that there was dirt under the grass, she bit the existing grass to get to the dirt, and started digging holes faster than we could fill them. We now have a yard full of dirt. We've tried replanting grass twice (seeding), it grew full one time and the dog tore it up again. Bottom line - I can't take it anymore and want to put down sod, but want to be sure that she can't dig it up. I know there are some brands that are more durable, and our local garden shop couldn't give a good recommendation. My mom has a very thick kind (she doesn't know what it is), and when our dog was there for a few days, she couldn't pull it up to eat it and dig. The dog is not bored, or seeking attention - the dog is walked, has toys, treats, and we are out with her at least 2-3 times a night. Both dogs sleep in a large kennel so the one cannot dig at night. She's a sweet dog, but she just eats grass! Any recommendations? I don't want to spend the summer out back in dirt!
