So I posted last week about my dog barking at me, she is 5.5 months and I'm really struggling with her. I'm just back from a walk which was lovely until the last 5 minutes where she went bananas jumping at me, biting my arms through my coat. It was truly frightening and I've included a photo of my arms, this was done through a coat so I don't even want to think what they would be like if my arms were bare. She was great for the most part but near the end, there was a light sunken in the ground, we were walking on the grounds of a hotel. She stared into the light then dragged me to the next one and that's when it started. I stayed calm even though I was genuinely scared of her. She eventually stopped and flopped down. It was like the zoomies, just a vicious version. We're doing our best with her, she gets lots of attention and exercise and had been at puppy class earlier this evening with my husband. I've noticed a gradual disimprovement in her behaviour over the last 2 weeks, barking at me and going a bit crazy at times but this was the worst yet. She did something similar about 2 weeks ago but nowhere near as bad as this. I'm thinking this can't be normal. I'm sure people will say we need to do more training with her but we're doing our best with her. I'm finding I'm nervous of her now, especially when the kids are around her, we have 4 kids and the youngest is only 5. Any useful advice welcome. Do we have an aggressive dog on our hands, cos it certainly feels that way. I couldn't attach a photo for some reason.
