To reduce tension between children and your pet, you could try the following:
Give him a crate that is placed far away from the attention of noisy children.
Insist that they leave him alone when he is in his crate. If they want to pat him, they must be gentle, particularly around the neck.
Don’t let children go close to your dog when he is eating. Not only does it distract him, he feels territorial about his food and will think that your children want to take away his food from him.
Don’t let them play tug-of-war with him because this will encourage him to think that he can grab any item he likes.
Teach your children not to run past him and scream because their excitement can encourage him to become dominant aggressive.
Don’t tie him in the yard because your kids will only tease him, making him feel aggressive towards them. Then, they will attack your kids by springing on them when they least expect it while your children scream and run for cover.
Don’t let your children sleep with the dog even if they are very fond of each other. This is a very fragile relationship and therefore must be nurtured with great care. So, teach your child and dog to respect and cherish each other.
