I have had an anorexic bitch in my breed that are normally pigs,a nd also two that were not greedy from 5 months to two years and would occasionally leave meals, which worried me no end.
They were all without exception healthy and as they matured/got old became greedy.
The one who I label the anorexic would have been an acceptable weight for a sight hound, but too thin for my taste, and it meant she never ate enough to grow a really good coat. We got a lot of seconds with critiques saying, needs to body up, and out of coat.
In the end the only thing to do was to be firm about not overfeeding on days when she would eat and lifting the food until next meal/day.
With one that is really fussy (not just overfed so not hungry), it is important that waht they are eating is high quality nutriton so they get maximum nutitional benefit from what theya re eating.
My girl was on Arden Grange Prestige until she was three years old, a food I would normally only feed to lactating bitches or young pups, as it is much more nutrient dense.
