Chicken broth low sodium is a good topper

An scrambled or hard boiled egg from time to time

Rotisserie chicken very small scraps

Salmon is too expensive for the dog but those are the things I give our small dog from time to time

I'll add some foods like Orijen have salmon so maybe try that.

That is so sad some of you don't give your dog good quality real food and force them to eat just kibble. Dogs like that usually stink too. I say give them whole foods like salmon as a topper if that's what your dog enjoys. They give us so much surely you can spare him the pleasure of a good meal.
