According to Dr. Tina Wismer, medical director at the ASPCA’s Animal Poison Control Center, the information is false.
“This is not true,” said Dr. Wismer. “Dogs do not bloat from drinking ice water on hot days… They can be given as treats or put in the water bowl. Some behaviorists even recommend freezing toys or treats in ice for dogs to chew on.”
Bloat is most commonly seen in deep-chested large-breed dogs, Wismer added, and is caused by food or from a build up of gas. “Either can cause the stomach to rotate and the dog to develop gastric dilatation volvulus (GDV),” she said. The potential problem is that your dog could break or chip a tooth, but highly unlikely.
