Shih Tzu
Shih Tzus are popular pets these days, but they require regular companionship because they suffer from separation anxiety when left alone. They may be lethargic most of the time, but they can also be hyperactive at times. They are always affectionate, yet can become aggressive if caught off guard.
Alaskan Malamute
This lovely breed was created for solitude and cold, and they are well-known for their survival instincts, which can lead them to attack smaller creatures such as infants. When you own this breed, you must be very assertive, so children are not likely to listen to you. And if your child has breathing issues, such as asthma, their continual shedding could be harmful to you.
