Most Home Depots I've been too do not allow dogs... At least that's what the sign on the door says.
Kaji and other pups are always welcome. In fact, we get better service when Kaji goes! Ross use to have a corporate pets ok policy, but more and more stores are not allowing them inside. The only trend I've seen that stands the test of time is the more affluent the community, the more dog friendly it is. Since we moved last year, Kaji is now welcome to Coldstones to pick out ice cream. Great Danes have been spotted at stores like Staples, Best Buy... Etc.
