You know that brings back memories! My old soul I lost five years ago, Brutus, loved carrots! He even chose the carrot over the other “Pegi-table” they were veggies shaped treats for dogs. I would say do you want the carrots or the celery or squash, he would 100 percent choose the carrots! LOL He was a cocker spaniel.
Now my current dog Boston likes peppers. Just simple green or red peppers. He steels potatoes but chews and spits out. Boston is a King Charles spaniel.
