Dogs cannot communicate through words, but their actions, behavior, and body language can reveal their mental and physical health. Dogs may get sick for various reasons, including infections, injuries, or underlying health conditions. While seeing one’s beloved canine companion unwell can be distressing, being observant and proactive can make a significant difference in their recovery. Here are some telltale signs that indicate one’s pet dog may be under the weather. Changes in appetite Dogs love food and often finish their favorite meals and snacks within minutes. But if one’s dog suddenly loses interest in food or water or starts eating significantly less, it could be a warning sign. Their loss of appetite may be because of digestive problems, such as indigestion or constipation, dental problems like gum disease or broken teeth, or illnesses and infections. At times, dogs may resist a particular type of food due to allergies or sensitivities to certain ingredients. Conversely, an abnormal and sudden increase in appetite, despite providing sufficient food in regular quantities, should also prompt one to consult a vet. Vomiting and diarrhea Gastrointestinal issues are common in dogs and can be caused by various factors, including infections, allergies, or underlying diseases. Frequent vomiting, especially if accompanied by diarrhea, can lead to dehydration and should not be ignored.
