Dogs hide pain. It’s instinct — show weakness, become prey. So by the time you notice something’s wrong, it’s often been going on for a while.
Learning to read the subtle signs is the difference between catching something early and dealing with a crisis. Here’s what to watch for.
Appetite Changes
A dog who suddenly stops eating is a dog with a problem. It could be dental pain, nausea, infection, or something more serious. Don’t wait it out.
Conversely, a dog who suddenly eats ravenously might have diabetes, thyroid issues, or parasites. Any significant change in eating habits warrants attention. Appetite is one of the best health indicators you have. Pay attention to it.
Energy Level Shifts
A normally active dog who becomes lethargic is telling you something. It could be pain, illness, or emotional distress. A normally calm dog who becomes hyperactive or restless might be experiencing discomfort or anxiety.
Know your dog’s baseline. What’s normal for them? When do they usually sleep? When are they usually playful? Deviation from baseline is the red flag. Not the behavior itself, but the change.
Bathroom Habit Changes
Frequency, consistency, color, odor — these all matter. Diarrhea, constipation, straining, blood, or excessive urination are all signals.
A dog who suddenly starts having accidents in the house might have a urinary tract infection, not a behavior problem. A dog with dark, tarry stools might have internal bleeding. What comes out is a window into what’s happening inside. Don’t look away.
Behavioral Changes
Aggression, withdrawal, excessive licking, pacing, or hiding — these can all indicate pain or illness. A friendly dog who snaps when touched might have arthritis. A dog who hides constantly might be in pain.
Behavior is communication. When it changes, something is driving that change. Don’t punish the behavior. Investigate the cause. The behavior is a symptom, not the problem.
When to Call the Vet
If something feels off, it probably is. Trust your gut. You know your dog better than anyone. A same-day call is better than a same-week emergency visit.
Early intervention saves lives. And money. And heartbreak.
