The ideal age for your kid to have a dog is by the age of 8 years. By the time they turn 8, your kid must be mature enough to know the responsibility of raising and caring for a dog. From the Association of Pet Dog Trainers, you should wait until your kids turn five years of age to bring a dog at home. Meaning, if you are eager to bring a dog as a family companion, this is the youngest allowable age for your kid to be around dogs. While dogs and kids are a cute combination, parents should carefully plan to adopt and welcoming a dog in a family with small kids.
