The consensus is that, no, ice cubes alone are not a trigger for bloat. When a dog is hot, he may be inclined to gulp a lot of water down quickly. This rapid consumption of liquids could create a gas build-up in the stomach, which causes bloat. If your dog is hot, don’t leave him unattended with a bowl of water until you’re confident that he’ll lap it up slowly as this will reduce your dog’s risk of bloat. Be prepared to remove the water bowl if your dog is drinking too much at a fast pace.
