Check for the following signs of ill health or dehydration before you get too concerned : [substeps] Gently pinch a fold of the dog's skin at the back of the dog's neck or between the shoulder blades, and let go. <sep> (A) If the tear moves around, the dog is dehydrated. If it trips over the tear when picking up a bottle, it is dehydrated. (B) If the skin doesn't immediately return to the original position, your dog may be dehydrated. Gently press your finger against your dog's gums until the color lightens, then lift your finger. (C) Float your dog in a shallow part of the pool or open a drinking pan. See if there is still fluid clinging to your dog's food in the pan. (D) If it fails to close its eyes, it's dehydrated. Send your dog to the veterinarian if symptoms happen and the dog suddenly stops drinking.
