Input (English): [header] How to watch for signs of illness in senior dogs [title] Monitor your dog's food and water consumption. [step] As your dog ages, you should monitor how much food and water they consume. Watch to see if they eat and drink more or less than they used to. <sep> (A) Usually, senior dogs will eat more and sometimes drink more water, so you may notice your senior dog is not eating and drinking more or less than they used to. [substeps] Look on dog food labels or adult dog food labels. (B) Notice if they move more when they exercise. If they crawl or vocalize more than they used to, they may be a senior dog. (C) You should also notice the food they are eating. Some dogs may start eating only soft food instead of hard food. (D) If they do not drink enough water, check for signs of inflammation. [substeps] Monitor how often your dog urinates, needs something to eat, or drinks regularly.
