I just found out that my very busy Lab has sustained a microfracture. My vet has recommended 30 days of total rest, no exercise at all, so that she can heal. We are respecting this as best we can, but my dog is going out of her mind. She normally gets at least a one-hour walk period per day, and it is easy to see that she has energy to burn. Does anyone have any suggestions for keeping her busy during this period? Unfortunately, hydrotherapy is not an option in my area. Thanks!
