The thing is that after two or three weeks at home, when he got all his
vaccines, we started to leave the backyard door open for him to go out whenever he wanted to and we walked him several times a day so he never had the need of
using the pads again, the problem is that he got so
used to doing his business outside that he forgot what the pee pads are for (he sometimes even takes his naps on them) and when we leave him
alone (usually not more than 4/5 hours a day) he does his business all over the house, even when we leave some «strategic» pee pads here and there.
