how to tell if dog is dehydrated
Signs of Dehydration in Dogs Include: 1  Lack of skin elasticity. 2  Dry, sticky gums. 3  Sunken eyes. 4  Too much or too little urination. 5  Lethargy. 6  Delay in capillary refill time (the time it takes for your dogâs gum to return to its normal color after you press your finger against it).ently pull up on the skin at the back of your dogâs neck. If the skin does not immediately spring back to its normal position (within 1 or 2 seconds), your dog is dehydrated and needs immediate attention. The longer it takes for the skin to return to its normal position, the more severe the dehydration.
