Not the long haired ones which is what I have they are so sweet and there is such a misconception that they are crazy and wild, our sweet lucy baby is very sweet and hardly wild but can sure play when she wants too. The short haired jacks will tend to shed when they grow a new coat and a little bit between that time. My grandpa has a short haired and I have a long haired they are one of the sweetest dogs you will ever meet and shower you with kisses. The long haired jacks are hypo allergenic too! =)
