my border terrier chews when we leave him so we decided to move him outside, we bought him a very expensive wood kennel and he loves it outside but 1 problem, he escaped a few days ago but thankfully came back after me crying for 5 hours, so we decided to get some rope and an ancor so he can't get out the garden incase the gate opens again, but now bacause hes tied up he wnt go to the toilet in the garden only on walks and i dnt know what to do as i cant make him go, advice will be really helpful, thankyou
