Yes, Home Depot IS pet friendly
Only service pets.
I believe only service dogs are allowed in stores, unless it is Petco!
Not sure call and ask
When I called there a while back asking them that very question, the woman I spoke to said something like "technically not but if the dog is well behaved they're OK with it." so I'd maybe call and see what they have to say before you go in (I usually do that anyway just to avoid awkward encounters)
