Bests & Worsts Reviews from Amazon

This is comparing the large, purple Kyjen bowl (https://www.amazon.com/dp/B00FPKNRG4/ref=cm_cr_ryp_prd_ttl_sol_0)to the small, teal Siensync bowl (https://www.amazon.com/dp/B01F3AZ5PG/ref=cm_cr_ryp_prd_ttl_sol_0). The purple bowl was purchased 2 years ago, while the teal bowl was purchased 2 months ago. They are being using with a 75 lb coonhound mix and a 55 lbs coonhound mix. Both bowls get the job done. I don't think that one design is particularly better than the other, but really just a visual preference for the human. However, since the teal bowl is smaller, more food is stacked, allowing for slightly larger intake for the dog (assuming your dog is large enough to consume large amounts of food at one time). The larger purple bowl has the food more spread out, which should take longer. I use "should" because the dog eating out of the purple bowl finishes sooner than the dog eating out of the teal bowl, but that's likely because she tends to enjoy eating more. Both bowls have roughly 1 cup of dry dog food in them as seen in picture. The teal bowl has raised non-skid detachable pieces, while the purple bowl has attached non-skid pieces. Since the teal bowl has already managed to lose 2 of those pieces, the large purple bowl wins in this category. (See pictures) Overall, I think either choice would yield desired results. If you have a dog that needs to just slow down some, the small bowl would work. If you have a dog that practically inhales their food, they'd probably be better off with the larger bowl to spread the food out more.
