Good With Dogs:⬛⬛⬛⬛⬛⬛⬛
The Bolognese Dog would do fine in your family home. Just make sure the dog gets the exercise he/she needs every day and they will be happy to play with the family when your siblings get older. An adult dog would be the best thing for your family, as raising a puppy takes a lot of work and it is not fair to expect your mother to raise four children and a puppy.
The Bolognese Dog should be fine for yourself. But remember, an adult dog that is well trained and well exercised will not be destructive. But crating your dog will give you peace of mind knowing that the dog is in a safe place at all times.
A puppy in general is not for you. Puppies need a TON of socialization time, exercise and work put into them. An adult dog is what you need. But not a Bolognese Dog, as they need at least an hour of exercise a day. Unless you plan on adopting an adult or senior dog, do not get one, as most breeds of dogs need at least an hour a day.
Unless you've met a Bolognese Dog that has barked at a leaf when it blows by, your assumption makes no sense. No well trained, well exercised, socialized dog will 'go crazy' over a leaf blowing by. If you plan on getting another dog while your senior dog is alive, please do introductions slowly and understand that your senior dog was there first. He/She deserves as much time if not more as the new dog.
