• When deciding on family rules (e.g. no jumping on beds, no paws up etc) consider the impact this may have across family members. If you never allow paws up or on beds then will all family members be able to interact with the dog when they have 4 paws on the floor? If not, can you add platforms or raised areas or have a specific sofa the dog is allowed on to allow everyone to bond. 
• If you have family members who collapse, faint or have seizures one vital rule can be no playing while lying down and no 'body' playing (e.g. encouraging chasing hands, fist and mouthing play) as this can result in your dog harming the family member when they collapse thinking its a game. 
• Have a plan for what happens to the dog during medical or distress events (such as seizures, meltdowns, self harm etc) to ensure the safety and wellbeing of both the dog and disabled person. If a dog is present during medical or distressing events we recommend you shower your dog in treats. 
•   Consider how rules and boundaries are communicated to individuals with communication or understanding difficulties. That might mean using PECS, repetition - going over the rules several times a day in the lead up to the dog coming home and it might mean having a plan for keeping the dog safe and not scared during meltdowns (e.g. crate in multiple rooms so puppy can be quickly removed from the room, placed in crate and given a high value chew to keep them entertained and ensure your dog doesn't make a negative association. 

All dogs are able to harm children but when they're puppies, without careful management your child will end up regularly getting jumped on, scratched and bitten. My top tips for preparing your children for a dog are:

• Have a schedule for your dog and children  so your dog is resting in another space at high emotion or high child energy times of day (such as when they've just come home from school and when your child is eating. Explain/ show the schedule to your child so they're prepared that they won't be playing with their new dog 24/7.
• Ensure rules about interaction are given in a format suitable for your child.
• Practice gentle & correct handling  with a toy dog before your dog comes home.
• Make a game out of practicing responses, for example every time you say 'puppy jumps up' ask the child to turn their back & cross their arms. 
• Explain where puppy will do certain things and where the child will be when that happens (that can mean things like 'you will sleep in your bed in your bedroom as normal and the dog will sleep downstairs in their crate in the living room).
• I highly recommend you never leave under 10 year olds unsupervised with dogs.
