I have two jack russel x australian terrier pups which are coming up to 6 months old. we trained them to go to the toilet inside on newspaper which by about 4 months was working pefectly. now we have installed a doggy door and are now trying to change their toilet habits to going oustide and feel like we are starting the toilet training all over again ! we have fake grass outside which they have used since we got them the times that they have been outside and have also put newspaper down outside so they can see that its moved and although they do go outside sometimes there are now there are accidents inside again as they are obviously confused and with us not being home all day we dont have much control in sending them outside eachtime they need to go ! does anyone have any pointers or has been through this themselves ? will they eventually understand that they need to go outside ??
