Can Dogs Get Depressed? Signs and What to Do

Dogs do not speak, so their emotional states are communicated through behaviour. When a dog stops doing the things that previously engaged it, sleeps more than usual, and withdraws from interactions it previously sought out, something has changed. Whether this constitutes depression in a clinical sense is a question of semantics; that it reflects a changed and reduced quality of inner life is not in serious doubt.

For French Bulldogs specifically, the risk of depression-like states is higher than in many breeds. Frenchies are deeply social dogs that form strong attachments to people and other animals. Disruption to those attachments, or to the patterns of daily life that provide structure, is more likely to produce observable mood and behaviour change in a French Bulldog than in a more independent breed.

What the research says

Dogs share brain structures with humans that are involved in emotional processing, including the limbic system. They produce the same hormones associated with emotion in people: oxytocin (associated with bonding and comfort), cortisol (associated with stress) and serotonin (associated with mood regulation). The neurotransmitter systems that drugs like SSRIs act on in humans are present and functional in dogs.

This does not mean a dog’s experience of low mood is the same as human depression. But it does mean that dogs have the neurological hardware for something meaningfully analogous, and that changes in brain chemistry can produce changes in mood and behaviour.

The observational evidence is consistent with this. Dogs that experience major loss or disruption show reliable patterns of behaviour change that improve with appropriate support and, in some cases, with medication that acts on the same systems as human antidepressants.

Signs to look for

The following behavioural changes, when persistent and not explained by a physical cause, suggest a dog may be experiencing low mood.

Reduced food interest. For a French Bulldog, which is typically highly food-motivated, loss of appetite or indifference to food is a significant signal. A Frenchie refusing meals, or showing less enthusiasm at mealtimes than usual, merits attention.

Reduced activity and initiative. A dog that no longer initiates play, that lies in one place for extended periods, that does not greet you at the door with its usual energy, is showing reduced motivation across multiple domains.

Increased sleep. Some increase in sleep is expected as dogs age. A noticeable step-change in sleep duration without a corresponding health explanation is worth noting.

Withdrawal from contact. A dog that previously sought human contact and now does not, that moves away when approached, that does not seek its usual proximity to household members.

Reduced responsiveness. A dog that does not respond to cues, sounds, or stimuli that previously produced a reaction. This can include not responding to its name being called or to the sounds associated with walks or mealtimes.

Changed posture and expression. Ears held flat, eyes appearing heavy or less bright, tail held lower, a general reduction in the alertness and forward orientation of a healthy, engaged dog.

Physical health first

All of these signs can also indicate physical illness. Reduced appetite can mean dental pain, gastrointestinal problems, kidney disease or any number of other conditions. Lethargy can be hypothyroidism, anaemia, pain or neurological disease. Withdrawal can be a pain response.

Before attributing any of these signs to mood, a vet visit is essential. Assume a physical cause until one has been ruled out. A dog that is ill and is not treated because its behaviour is attributed to depression is a dog that is suffering unnecessarily.

The sequence is: notice changes, see the vet, rule out physical causes, then consider behavioural and emotional explanations if the vet finds nothing.

Common triggers in French Bulldogs

Loss of a companion

French Bulldogs form strong bonds with the people and animals they live with. The loss of a companion animal, or the departure of a household member (a child going to university, a partner moving out), can produce a genuine grief response. The dog looks for the missing individual, is unsettled, and shows the signs of low mood described above.

This is real. It is not the dog “acting out.” The appropriate response is additional gentle engagement, consistency in routine, and time. Most dogs adjust within a few weeks; those that do not may benefit from professional support.

Changes in human routine

French Bulldogs adapt to routines, and when routines change significantly, they are affected. An owner starting a new job that requires long absences after a period of working from home is a common example: the dog has habituated to constant company and then abruptly loses it. This is both a separation anxiety trigger and a mood trigger, and the two are related.

The separation anxiety guide covers the specific pattern of distress during absence; low mood may accompany it or persist after the acute separation anxiety is managed.

Moving home

A house move removes all the familiar environmental cues that provide structure to a dog’s day. This is temporarily disorienting. Most dogs settle within a few weeks as new routines and associations form; a dog that remains unsettled for longer than a month warrants attention.

Chronic pain

Chronic pain changes behaviour in ways that can appear as low mood: reduced activity, reduced engagement, changes in sleep and appetite. French Bulldogs are prone to spinal problems that can cause pain without obvious limping or crying. If a Frenchie has become less active and less engaged with no obvious trigger, an orthopaedic or spinal assessment may be worthwhile.

What helps

Consistency and routine. Predictable patterns of feeding, walks and contact provide structure that supports emotional stability. A dog experiencing low mood benefits from routine being protected rather than disrupted further.

Gentle increased engagement. Invite but do not force interaction. Offer play and contact, but accept it if the dog does not engage. Pushing an interaction can increase withdrawal rather than reducing it.

Physical activity (within limits). Movement and exercise have well-established mood-supporting effects in dogs, as in people. Within BOAS limits and heat restrictions, ensuring the dog continues to have regular walks and activity supports recovery.

Social contact. For a dog that has lost a companion, appropriate contact with other dogs through structured, positive introductions may help. This is not a replacement but a supplement to human engagement.

Environmental enrichment. Puzzle feeders, hide-and-seek games, new toys and new smells give the dog things to engage with that can compete with low-activity withdrawal.

Professional support. For dogs that do not improve with the above measures, a veterinary behaviourist (not just a trainer) is the appropriate next step. They can assess the dog comprehensively and, where appropriate, recommend medication alongside behavioural support.
