It’s not out of the ordinary for your dog to skip a meal or two, especially if it’s hot outside — but any more than this should be a red flag that something’s off. Two days without eating is a clear sign that your dog needs an examination. If your dog is usually well-behaved but begins raiding the pantry or garbage, you should take them for a checkup. Lethargy is a sign that something may be troubling your dog. A lethargic dog may be uninterested in playing, going for a walk, or participating in activities they usually enjoy. Normal fatigue or sore muscles can sometimes be due to high temperatures, but you should see a vet if symptoms persist for more than two days. Take your dog to the vet if they have any of these symptoms: worms noted in the stool, diarrhea for more than 24 hours, straining, blood or mucus in the stool. Even in an overweight dog, sudden weight loss should prompt you to take them to the vet. Losing weight quickly and unexpectedly could indicate a serious health condition. If your dog drops in weight by 10 percent, bring it to your vet’s attention. Take your dog to the vet or an emergency vet clinic if they show any of the following symptoms: open wounds or possibly broken bones, such as from being hit by a car or other trauma, stopped breathing or unconsciousness, repeated vomiting or vomiting blood, seizure, sudden collapse or difficulty breathing, bleeding from their mouth, nose, or eyes, possible poisoning from eating something toxic, extreme pain, seen as whining or shaking, hard and swollen abdomen.
