How old were your boxer's when they were house trained. Tank is 5 months and today for example I took him out twice in 40mins and then when I come in I use the bathroom and when I come out he is squating in the living room so I say no and take him outside and he sits there looking at me for 10mins as im saying Tank go poop. So I get his leash out and take him out to the middle of the yard and after another 5 mins he finally goes poop. So im I still asking too much? I mean to be outside twice in 40mins and not poop then try to poop in the house not even 2 mins later. I should add that it was raining out but he still peed and the last time he went out it wasnt raining just wet.
