I think it's because they are young and with time they will understand the patio is for playing and the planting areas are for pottying. It is like pee pads. Puppies go on the pad but still will go on the carpet. When they finally understand what you want they stop going on the carpet. It just might take a little longer for them to catch on this way.
Keep an eye on them while they are playing on the patio and if you catch them starting to go bring them to the planting area and tell them to go with lots of praise. Even if you can't get to them fast enough and they are finishing up I would tell them no, bring them to the area and tell them the command for potty.
Ignore the accidents you don't catch them doing. |
