Probably would help to know where you’re at, pics and all that. But just for reference I have 3 dogs and have 85/15 TTTF/KBG (GCI Cool Blue). My dogs may not wrestle as much as yours but the lawn in general holds up well. One my dogs always kicks the grass after she does her business and I don’t really worry about big bare spots. I leave the lawn pretty tall so that may help as well.
