But ever discover your usually bright-eyed, bushy-tailed canine seem to down or show another signal of low temper at sure occasions of the 12 months? Could man’s finest good friend be affected by SAD too?
Newsweek requested the consultants if canines can get SAD and whether or not seasonal modifications can have an effect on your pet’s temper.
What Is Seasonal Affective Disorder (SAD)?

In most situations, SAD comes within the type of “winter depression,” which sees signs come up in late autumn or early winter earlier than disappearing within the spring and summer season.
Dogs and Emotions
There’s little question that canines are extremely perceptive and delicate beings, with the power to sense feelings and skim the facial expressions of people.
The American Kennel Club (AKC) says earlier research have proven canines mix listening to and sight to correspond blissful and indignant human faces with blissful and indignant vocalizations.
Researchers have discovered that canines can distinguish the optimistic sound of laughing from the unfavourable sound of crying. The canines have been discovered to be extra upset and stimulated by the unfavourable sounds than optimistic ones.
A 2018 study printed in Scientific Report, a peer-reviewed online journal printed by Nature Research, confirmed that canines can decide human feelings utilizing solely their ears (not less than for happiness, concern and unhappiness). They use the fitting aspect of their mind for processing unfavourable feelings and the left aspect for optimistic ones.
A 2016 examine printed in The Royal Society’s Biology Letters, a peer-review online journal, confirmed canines can acknowledge feelings in people utilizing information from totally different senses, which the examine stated is a capability that had by no means beforehand been noticed exterior of people.
Do Dogs Feel Sadness?
The quick reply? Yes and no. Speaking to Newsweek, the AKC’s chief veterinary officer, Dr. Jerry Klein, defined canines can actually turn out to be depressed and anxious. There have been stories of canines experiencing despair and loneliness following the lack of an proprietor or a “fellow member” of their pack, be it a human or one other animal, in addition to a change from their regular routine, Klein defined.
“But whether or not dogs get ‘sad’ is a little less certain,” Klein advised Newsweek.
Klein stated from a strictly scientific standpoint, there is not “strong evidence” that canines really feel what individuals would classify as unhappiness. “Dogs live more in the moment and don’t have the ‘self-consciousness’ or the tendency to inwardly ponder like people do.”
Speaking to Newsweek, Dr. Jose Arce, the president of the American Veterinary Medical Association (AVMA), echoed Klein’s ideas, noting that we do not know if canines really feel unhappiness in the identical approach people do. However, canines can positively expertise unfavourable emotional states resembling stress, nervousness, and despair.
Klein additionally famous there’s the argument that if canines do expertise unhappiness, it’s normally quick lived.
Can Dogs Get SAD?
The AVMA’s Arce advised Newsweek: “There’s no evidence that dogs suffer from seasonal affective disorder like humans do.”
The AKC’s Klein defined that till not too long ago, there hasn’t been an official analysis of SAD in an animal, as there was no mannequin for it. However, current research on hamsters and grass rats might show that seasonal modifications can negatively have an effect on animals as properly.
“When exposed to less sunlight, hamsters and rats acted depressed. The study discovered that there was an alteration in the chemistry of the rodents’ brains. The hippocampus (area of the brain) shrank, which is thought to be a reason for depression,” Klein stated.
While the examine hasn’t been immediately performed on canines, it signifies that the possibility of SAD affecting canines is feasible, and that animals can expertise modifications in mind chemistry and temper during times of shorter days and fewer mild, the AKC’s chief veterinary officer stated.
“A more real possibility is that SAD indirectly affects dogs because of how their owners act and feel when they are depressed during periods of less light,” based on Klein.
Veterinarians on the People’s Dispensary for Sick Animals, a U.Okay. veterinary charity, additionally say “pets can’t actually suffer with SAD,” based on an October 2020 PDSA article.
The charity explains: “If they [dogs] seem a little off over the gloomier months, this could just be because we’re [the owners] feeling down and we naturally project our feelings onto our pets.”
Certified animal conduct advisor Steve Dale advised PetMD, a pet well being web site that includes articles written by veterinarians, in 2017 that the moods of pets are mirrored by that of their house owners.
“If we’re moody around the house all day, cats and dogs can pick up on this,” Dale said.
Dale additionally stated when canines seem like down over the winter months, it may probably be a sign of boredom, with them naturally participating in much less exercise outdoor in the course of the colder months.
Dr. Karen Becker, an integrative and wellness veterinarian, advised PetMD in 2017 that some canines additionally sleep extra and are much less energetic in the course of the winter. This raises the query of whether or not their signs are a results of their house owners being much less lively and engaged with their pets, “rather than true seasonal depression,” she stated on the time.
Impact of Daylight on Dog Mood
Dale defined people and canines share a lot of the identical mind chemistry, resembling how the hormones melatonin and serotonin are impacted by daylight. An improve in daylight sees the mind produce extra melatonin and fewer serotonin and each modifications can have an hostile influence on temper.
Therefore, Dale famous it’s fully attainable that canines can get SAD however there could also be different explanations, noting the limitation of there being no method to objectively measure or diagnose SAD in pets.
Becker additionally stated diminished daylight could cause Light Responsive Alopecia (also referred to as Seasonal Flank Alopecia) in canines.
Becker advised PetMD that scientists consider the situation comes from an absence of daylight publicity to the pineal gland, so canines residing in northern climates are extra affected than these in sunnier, southern climates.
Signs of Depression in Dogs
The AKC’s Klein defined indicators of despair can embrace lack of vitality or curiosity in doing the kinds of actions one would usually get pleasure from as properly a lack of urge for food and a change in physique posture (a dropped head or tail) might also be seen.
Klein warned that this can be very vital that any canine displaying indicators of a change in conduct or urge for food at all times be examined by a veterinarian to rule out an underlying medical situation or ache. A medical situation would manifest the identical signs, so house owners mustn’t assume that these modifications are based mostly strictly on despair.
Other indicators to look out for that will point out your canine could also be experiencing unfavourable emotional states resembling despair and nervousness embrace not participating with different relations, whimpering or howling, aggression and modifications in sleep patterns, the AVMA’s Arce advised Newsweek.
Arce additionally highlighted the significance of speaking to a veterinarian when house owners discover these kind of conduct modifications. If the explanation for these signs are purely behavioral, your veterinarian can advocate methods to assist your canine. resembling “behavior modification, environmental enrichment, and the use of medications developed to treat depression or anxiety in dogs.”
Dr. Leslie Sinn, an authorized skilled canine coach and Diplomate of the American College of Veterinary Behaviorists (ACVB), advised the AKC in April that an underlying medical situation or persistent ache can set off signs of despair.
“In general, if a dog is slowing down or is reluctant to engage, especially in the absence of some life-changing event, then I would bet huge amounts of money that it is medical or pain-related,” she advised the AKC.
What to Do if Your Dog Is Sad
Apart from contacting your veterinarian as beforehand talked about, Klein recommends rising daylight publicity by waking up a bit of earlier and getting extra train outdoor. Exercise and exercise additionally make an awesome treatment for boredom for each you and your canine, he added.
Arce defined canines are creatures of behavior and the change in seasons typically results in a change in routines—resembling darker, colder days might imply shorter walks or much less frequent journeys to the canine park than in the course of the hotter months.
“This disruption of their routine, combined with less physical and mental exercise, could lead to signs of depression in dogs during the cold winter months,” he stated.
The AVMA president famous house owners can nonetheless present “the emotional safety and security of a consistent routine” by changing hotter climate actions with different methods for his or her canines to play, discover and bond with them indoors. This may embrace designated time for indoor play, encouraging foraging conduct with puzzle toys or snuffle mats or studying some new canine methods.”
The use of artificial sunlamps is often considered as a treatment for humans with SAD, however Klein explained there is no evidence to suggest this will work for dogs.
