Daisy is a very frightened dog and seemingly very untrustworthy of humans currently indicating perhaps an abusive owner in the past, due to being owned

Her foster carers are currently working on gaining her trust to a level that she can be more confident around people.

She does seem to be sociable with other dogs, however so this is a good sign and should help her development.

In terms of other training, her lead behaviour will need to be worked on.  She is terrible on the lead which could be due to her distrust of people and never having the proper training.  Once trust has been gained, then her lead training will be assessed and developed as much as can be before travel to the UK.
