My pups have never been picky eaters. They will eat ANYTHING. If it hits the floor, Thing 1 has lightning reflexes and gobbles it up immediately. Thing 2 will attack anything left on the counter, or in a shopping bag, or pretty much anywhere she can reach. They've always eaten whatever I put in their bowls with no problems.
However, the last few days, Thing 1 (who is 13 years old), has not eaten the food that has been put in front of him. A couple days he flat out refused it. Just stared at the bowl for a while and then walked away. Yesterday, he ate a couple bites and then walked away from it. Given his age, I was definitely concerned. So, I had the Princess pick up a couple cans of wet food yesterday while she was out and about. Both pups LOVE the "treat" of wet food. And I know very well that if I give some to Thing 1, Thing 2 is going to get huffy if she doesn't get that treat too (this could get expensive).
Anyway, this morning I put some wet food in each of their bowls --- underneath the dry. Thing 2 hoovered it all up like it was her last meal EVER. Thing 1 -- well that little rascal nosed the dry food aside, ate all of the wet and left every single piece of dry food for Thing 2 to eat for dessert. Ugh. Looks like someone will be getting wet food going forward. Age has its privileges I suppose.
