You hold down the pet then with your remote, mice, finger etc...
Move it inside on a platform or the foundation. It is too easy! I hope this helped you! Please give it a go I happened to me when I tried doing the 101 Dalmation challenge, my female dod wouldn't be able to go indide to her bed to breed and have puppies with the male dog, so i made her happy feed her, give her a kennel outside, pat her and trained her that's until
I relised I could just pick her up and put her inside. So what happened was when I said go here she would finish what she had done and then the box at the top of her to do list would disappear? It also made a "Beep" like should so I followed this method and she can finally go inside!
