Choosing the right dog for your family with kids need some research if you are new to the dog ownership. Families with kids need to pay attention on certain dog qualities such as temperament, size and energy level before adopting or buying a dog. 

Kids like to play with dogs. Sometimes they forget to respect dog's cue to back off. You need a dog that won't mind if his hair or tail gets pulled. Size is the another important consideration. This is for the safety of children as well as for dog. There are dog breeds that are very good with children but too big; especially with small children who may be accidentally stepped on or knocked over. 

Some dog breeds that are good with children have high energy or activity levels than others. If dogs don't receive the exercise they physically require, they are more likely to develop behavior problems such as excessive chewing or barking. Select a dog breed that loves children but requires less exercise if your family is not so active.
