The title is somewhat misleading because what I want to say is the sugared water is good for a vomitting dog especially when there is a suspicion that it was poisoned. The sugared water neutralizes the potency of the venom. Another use of sugared water is when the dog has diarrhea, it gives energy so it will not feel so weak. PS. My favorite dog Barbie was having diarrhea that started at midnight last night. From then on until 7:30 this morning, she had excreted 5 times with wet feces, obviously diarrhea. We gave her sugared water and after 5 minutes, she was able to eat breakfast. I hope she is okay now because 2 hours ago, the vet who makes house calls arrived and gave her a shot. It's already past lunch time and I our housemaid has not texted me yet, that means Barbie is okay.
