I have a 13 year old Yorkie and 10 and 4 year old Lhasa Apsos. Up until a month or so ago I had someone come in 2-3 times a day to let them out for the toilet, check on them etc while my Fiance and I were at work. Unfortunately she now can't come in and they're being left in for a few hours themselves. We have an indoor toilet for them but they seem to point blank refuse to use it. We've used voice commands, tempting with treats, all the normal training things to try and get them to use it but they won't so we're coming in to a lot of accidents every day. I kept putting my Yorkie on their toilet last night as I knew he needed the toilet and he wouldn't do anything and when I turned my back, he came off of it and peeped on the floor. I know they can control their bladder so I'm not sure what the issue now is (pay back for being left alone?). Any suggestions welcome please.
