Jealous St. Bernard Becomes Aggressive
My 7 month old St. Bernard puppy just came to live with us 3 days ago. Tonight, my husband was talking to our 6 yr old Labrador & the St pounced on the lab, held her down & was trying to bite her in the head. My husband panicked, & started yelling, but when I ran into the room, I gave the st her commands & she stopped & looked at me which gave hubs time to pull her off our lab.
Why would this otherwise docile puppy behave in such a jealous manner? And is there anything we can do to be sure it doesn't happen again? We have small grandchildren around daily.
