Just like humans, dogs can develop various forms of cancer. The difference here is that your dog can’t vocalize the pain and discomfort he feels nor point out the changes that are going on in his body.

If your dog has been eating less (due to illness or food preferences), then he’d naturally lose weight. But, if he has been eating and drinking like normal but is rapidly losing weight, it’s a sign that there’s something going on inside his body.
