I have a 8mth old JRT. I do the traing,feeding,bathing and walking. Tonight while sitting in the chair with me, my husband came to pet him and talk to him and he nipped him in the face. Thank god he didn't bite hard but it made my husband mad. I think my dog was asleep,not really sure. Later on my JRT barked at my husband as he past the same chair, (my JRT was near me on the chair). My JRT got down and went towards him barking when I grabed the back of the neck to halt him and said "NO,NO" and sent my JRT to bed. Is my JRT being aggressive or possive? My husband is threating to get rid of my JRT if he shows agressivness. Can some help me. I need to know what to do when this happens.
