How long does it take 10 pound dog to dehydrate having been on iv fluids two and one half days drinking water and had subcutaneous fluids for a four hour trip?

If You Supply The Dog With Decent Amounts Of Water It Should Be Fine On The Trip.A Hint To Figure Out If Your Animal Is Dehydrated Is To Pull Up On Their Scruff (The Skin Of The Back Of The Neck) And If It Goes Righ Down Fast Your Animal Isn't Dehydrated If It Takes A While The It's Dehydrated Or If Their Gums Are Dry That Is Also A Sign Of Dehydration! Hope That Helps :D
