Lately, I have been having problems with my new husky of a year old with killing ducks that are jumping the fence from the canal. Just to tell you a little about her, i got her when she was 2 months old and since the day she came i introduced my pigeons and the ducks from the canal. I used to make her lay down when she saw them as a sign of submission and positive reinforcement when she ignored them flying or walking. She lives indoor but goes outside often, as she loves it. She never looked at a bird until 2 weeks ago that she killed a duck that jumped over the fence. We scolded her for killing it and left her tied up as a negative reinforcement. The weeks passed and she had gone back to normal not looking at any of the birds. Then all of a sudden she killed another one in the few minutes that i had gone inside from watching her. i did the same as last time but now i feel like i can't trust her not even with my 2 chihuahuas even though she has never been aggressive or harsh with them. The canal is right next to my fence so its inevitable that the ducks would enter especially since they love coming to eat the leftover pigeon food that falls. I don't know if anyone has experienced something similar or has a better idea of how to stop her killing them. I greatly appreciate any responses, thank you for your time and sorry for writing so much.
