My boy gulps his food also, so I add 1 spoon of food at a time to his bowl & it slows him down….I also soak his kibble in warm water then when the kibble is soft, I fully drain all the water & cuff 1/2 cup sections of the soft kibble in the bowl with my hand & squeeze all the water out, then I put the kibble in a blender, you have to make sure the water is thoroughly drain or some kibbles goes like a gluggy ball, I like the kibble to be lite & fluffy after I put all the soft kibble in the blender I add some boiled chicken, sweet potatoes & some broccoli & blend for about 3-5 seconds… that fills him up more, that way I just take 1 meal out of the freezer the night before & thaw in the fridge for the next day, then I just add half of a cooked meal & about 1 cup of the soft kibble for breakfast & the other half of the cooked meal with more kibble that I soak about 40-60mins before his dinner is due…. “Earthborn Holistic” Ocean Fusion kibble softens within 40mins in warm water & the protein is only 22% its a lower protein kibble if you need one for her liver… http://www.earthbornholisticpetfood.com/us/dog_formulas/ocean_fusion/
