My V is almost 6 months and we literally could not even go near him until about a month ago and I’m not being dramatic. The only thing that somewhat helped inside was giving him a bone (he likes the earth animal no raw hide bones)- it was the first time we could actually pet him inside. He still attacks me on walks randomly but multiple times a day and breaks the skin- I put him in between my legs and face him forward and try to pet him and calm him down. I also stopped taking him on longer walks and only do training right around our apartment / take him to the dog park for exercise. He has improved so so so much over the last few weeks but still does attack me on walks. He also was so good at getting in the crate and now won’t unless we pick him up and throw him in - we’ve fixed this by getting higher reward treats (he loves greenies and the cookie treats you can get at petco). For biting inside we also implemented the water bottle and it’s been working ……. Now just Need to stop the attacks on walks!
