I don't know when our Loo-C-Loo puppy dog began eating very dainty-like, as it looks like she eats her chow in rows, you know, to keep the bowl looking clean and smart I suspect. When we had two dogs in the house, she did eat rather slowly. However, she ate it all in one fell swoop less the little pipsqueak, Lucky (rest his doggy soul), even so much glanced at her bowl, that was not going to happen on her watch! So what goes through a dog's mind to eat chow in "rows"? I guess we will never know...but maybe a “call” Dr. Doolittle is needed.
