I thought things were improving but today is a major step back. Started this morning with breakfast, followed by biting of my feet and clothes. Went for walk, ok on long lead when allowed to play, walked a little way ok on short lead, major pulling and tantrums on the way back, tried stopping, restarting for about 20 mins, dropping food on path, eventually gave up, after treat snatched and bitten, bleeding finger. Tantrum back at home when tried to take lead off, sat when told but as soon as I tried to unclip went mad, new behaviour. Then had to go to dentist (broken filling, yippee), so she had good sleep and rest. Returned and fed lunch and mad behaviour starting again. Wants to either go in part of garden where she's not allowed and eat soil & sticks, or inside wants to bite feet and clothes, plays for few minutes with me and toy but then back to bad!

Have had to put her back in playpen to calm down. Trainer said high protein in puppy feed (R. Canin junior medium) could make hyper. Anyone any ideas please, please?
