For those who may consider fostering Frankie, here are some considerations:
A dog with mega-e is normal is all ways other than the feeding challenge; which means that some will still eat verboten items if given the chance.
A foster home must be able to follow an established feeding routine and quality of food.
A car seat for children is an easy, lightweight, secure feeding chair for a dog... check your recycling lists.
There are medical alternatives for appropriate patients and amazing mega-e support groups.

We have a foster dog in our care with mega-e. Dolly is gaining weight and normal in all ways...even loves to countersurf, like every other springer.
