Hi Bill,

it is certainly very good that your dog has the opportunity to run in your backyard. Nevertheless I think it would be good if the two of you could explore some other areas as well. I'm sure your dog wants to smell something new every day. She won't be able to do that in the backyard, I suppose.
So I think it would be very good to go out, maybe you have some nice areas in your neighbourhood (?), grass, fields, woods, or just places, where other dogs have gone before you and so she can collect some information. I think this is essential for a dog.

Whenever i leave home, i put some small treats in a lavatory roll (just the roll without the paper!). One treat my dog gets directly from me and the other two or three i put in the roll - then i close the roll and give it to her. She loves to bite it, to tear it apart and finally finds the treats.
Maybe this would be something interesting for your dog as well. Maybe she realizes that the other stuff she chews or bites has nothing special to offer ...

I hope this is some help for you.

All the best and

nice greetings from Vienna

Michael
