A bit better this morning, but still naughty

The walk this morning was better, but Flash was still decidedly reluctant to come back. First time, he didn't even take any treats... VERY strange! He also had times when I called him, he looked at me... then turned round and ran the other way - just like he used to do before he was on the vegan diet. At the end of the walk, it took about 10 minutes until he returned to me! This time, I just stood still and waited for him rather than walk away from him. I guess it is the food that he ate yesterday in the park...
