Animal Instincts slow feed bowl has been designed to stop dogs eating too fast which can result in poor digestion vomiting choking & swallowing so much air that they develop bloat. The slow feed bowl is a heavy duty plastic bowl which is split into four feeding zones each zone designed to stop the dog putting its full snout into the bowl meaning the dog cannot get as much food into its mouth at once compared to a standard bowl. *** Colour cannot be guranteed*** Size guide: (approx) Medium 16.5cm Large 20cm Jumbo 25cm
