For these microscopic dogs, free feeding isn't a bad idea I think. I could be wrong, but their metabolisms seem better suited to nibbling.
Otherwise, I just don't find it health for management or for regulating what goes into them, when picking is encouraged. It's a behavior that makes traveling or boarding difficult, as well as administering meds when needed. Pickers are harder to transition to special diets, too.
Lynn was a terrible picker - she had a "starved dog" appetite - she was so far past a healthy weight she was burning muscle and felt a bit nauseated all the time. The vet said, "Oh, you've got a smart one on your hands - she'll probably always be picky!"
Hee. That was like waving the red cape.
She needed crate rest anyway, so during that time she got offered really yummy (bland) food, at regular, but very short intervals. After that the same thing, until she was wolfing down her food when it was offered, with everyone else.
She actually also didn't know what kibble was and still really hates it, except Bil-Jac. That doesn't bother me, as I intend to go to all raw with her, but her tummy isn't ready for non-cooked food yet and I don't have time - or space - to homecook yet another special diet (eek!). But, she was picking at the bones I started offering, too. That definitely wasn't going to work - I don't have a house full of crates and it's eat it or lose it at dinnertime!
The regular feeding got us over the hump with her tummy issues and the lack of enthusiasm, and the last weight check at the vet produced smiles all around from the techs who came out to say hello.
Gina, if you are reading this - she's stretched out in the doorway in that "lion pose" and she looks like she thinks she ought to be 50 pounds! A rescue person contacted me and said she had a dog last year that was puppymill bred and starved, and she was half the size of a regular Leo - she had papers and everything. She looked less Leo-like than Lynn!
