We do ahve a small garden, but Bella has decided it's not for doing her business in. So apart from our 2 long off lead walks (morning and late afternoon) we go out at least 2 more times a day. We do a very very brief wee walk at lunch as it is too hot, and at night we do 10-15 minutes around the block. More often than not we go somewhere (e.g. friend's house) where she comes along and is more than happy to toilet in stranger's gardens hehe...so she usually gets more opportunities to toilet apart from her (at least) 4 walks.
