Hi Beachgal, we can relate! Our Barley is a scarfer as well and without one of our "slow feeding bowls" he chokes and coughs his food back up (not to mention, he finishes so fast he then goes over and eats his sister Lily's food before she's done).
There are many bowls available that are designed to slow down your dog's eating. You may need to experiment with a couple to find the right one for your pup. Check out our coverage of over 35 options in our article comparing the best slow feeder dog bowls.
