We have two male Peking ducks..they are 6 months old. When we first got them we did not know what they were. We have a large yard and let them out during the day. They have two pools and their home which they go into overnight. Lately, they have become very aggressive..especially the larger one. To the point that as soon as my dog comes outside they’re doing anything and all to attack him and me if I try to stop them. One is more aggressive than the other..I feel so bad for my dog because now he can’t even come outside in the yard. I try to keep him separated and follow him to protect him from the ducks but the whole time they are searching and sneak up and then rush him to attack. I know they can’t harm him much because they do not have teeth. If I’m sitting down holding my dog in my lap they will come and try to bite his tail or leg and bite me..It’s getting to a point I really don’t know what to do. I guess they’re trying to show dominance and shown that this is their land idk? But I can’t keep this up. My dog and I should be able to enjoy our yard also. Does anyone have an idea what I can do or how to stop this behavior? I just want all of us to enjoy the yard together without feeling like we’re going to war each time we go to the backyard.
