Raw Feeders - border collie does not seem interested and is lethargic

[Nancery]

I started wall feeding my border collie yesterday and today she seems quite subdued. She is normally very lively and quite demanding but she isn't quite herself. I've been giving her just chicken to gently introduce it to her system so nothing too difficult for her. Is this normal and will it take a while to get used to it?
Experiences will be great to hear about thank you! I'm a bit nervous about not doing the right thing!

RAW not 'wall'!

She is a border collie, she most probably thinks you are trying to poison her and is now deeply suspicious of your every move and its exhausting her

Yes, collies are suspicious of change. Give her a couple more days and she'll probably get used to it. If not, it may be that she simply doesn't like it - ime, collies are also quite fussy about what they will and won't eat.

I take it back, she's loving it!

Maybe she has done some research, asked some other dogs,rang the vet and surfed the net whilst you were out

That would actually not surprise me!

She seems more satisfied too, not the usual food bowl banging going on (unless she just doesn't want more chicken!)
