The English Toy Spaniel
Although English Toy Spaniels are small and adorable, they are not the best around kids. They often perceive kid’s rough play as threatening, and can act out if they feel they are being mistreated. Strong leadership is crucial since they can become very dominant in the household, leading to aggressive behavior towards both children and adults. As with every breed out there, proper training can combat all of these issues.
Greyhound
Thanks to their energy levels and incredible speed, this breed has been bred for racing. They require constant running, which can be hard for parents with little ones to chase after. They have a tendency to attack small animals, as may be the case with small kids. They also don’t tolerate kids cuddling or hovering and they hate rough play.
