The Maltese is such an adorable breed. Look at that face. Very sorry for your loss, it's one of those things we know we're all in for as pet owners, we know the worry when they're sick and we know the gut-wrenching grief when they're gone, but we do it anyway because of all the preceding years of joy. The important thing is Bella enjoyed her life with you. Your sadness right now is a testament and a tribute to this little character. Time, of course, will heal and there's nothing else to do but to let it do so.
