Leash Pulling when walking with kids
Hi I have a 4 month old male GSD. I usually walk him myself and all is going ok apart from a bit of leash pulling which generally happens on the way home but all in all the walks are enjoyable and he does really well. So I also have 3 children under 10 who are usually at school when I walk the dog but I want to add them into evening walks with the dog a sort of a pack walk, but Everytime we all go out its like Im walking a different dog. I have them walk slightly ahead of us and he pulls, lunges and howls to get to them. I try to make him sit Everytime he pulls but he's really restless and starts pulling immediately when we start to walk again, if he walks ahead he is better and seems more content but is constantly looking across/back checking where they are and is on the whole alot more reactive/restless than usual. When we stop and the kids are playing I keep him on leash beside me praising him when he's in a calm state but he whines, pulls and is really jumpy until he gets closer to them. When he's off leash he's ok and acts much more like normal but Im not totally comfortable with having 3 kids and an off leash puppy to contend with until Im way more confident in his obedience. Inside the house he is pretty calm with the kids I usually keep them in separate rooms and give 10 minute sessions of us all sitting together throughout the day when puppy is nicely sat on floor and giving treats/praise for nice behaviour or when the kids come in the kitchen have them gently petting him and he gets praised for calm, gentle behaviour. He does tend to follow them if the doors left open especially my youngest (4) as I have gotten the kids in the habit of giving him treats when he is displaying respectful behaviour so he runs into the room there in sometimes and sits nicely expecting a treat until I call him out. Sometimes he goes in and lays on the floor and doesn't seem to want to leave but as I want to supervise all interactions I prefer to keep him in the kitchen with me and have the kids separate playing in the front room.
Sorry for going on but should I be worried about this and does it sound like he is trying to show dominance over the children by trying to be ahead of them or could he be being protective. Any advice, opinions ect will be welcome, thanks.
