Poppy has always been on JWB, a few months ago it was hit or miss whether she ate her breakfast, but she would eat if you hand feed or she would eat it out of her kong...
I also used to mix pilchard/mackerel/sardines in with her tea 3 times a week, but when there was no fish mixed in she didn't want it.
This went on for a long time until a few weeks ago she had a bad dose of sickness and diarrhoea, 2 jabs, a 4 day course of anti-b's and a very empty tummy later, she has not turned her nose up anymore...
Now I give her 1/3 for breakfast and 2/3 for tea and when she's eaten all of her tea she gets her fish for dessert...
