Too many e-numbers!

Ginny had the doggy equivalent of too many e-numbers in toddlers today.  Hoping for signs of calmer behaviour and some consistent response to training being practised but that was sadly lacking today.  Because she is so small I can afford to buy best quality dog food and home cooked chicken - not exactly Waitrose but Aldi economy chicken fillets!  I'm thinking of changing to tinned Chappie but that may actually have e-numbers?  This shot summed up her attitude today.
Extra shows her sometimes behaviour on being put back in the car to go home.  Strangely she reserves the worst of it after the longer walks - the more she enjoys the walk the less inclined she is to go home.  This is her travel crate (a cat box actually) and she is fine about being in it - goes in willingly but once the door shuts there is this brief show of defiance - all over in a minute and not another sound on the journey home once the car starts.  Not sure how to train this out of her!
