Does Your Dog Still Pine For His Old Family? The Surprising Truth.


Dogs form strong bonds and attachments to their human families. When a dog gets adopted by a new family after living with a previous family, it’s natural for dog owners to wonder if their new canine companion still remembers their former home and family members.

This is an important topic for dog owners because dogs’ memories of past experiences, people, places and other dogs can influence their behavior and adjustment period in a new home. Understanding how dogs’ memories work can help owners manage the transition smoothly and build a secure new bond.

Dog Memory Capabilities

Research shows that dogs have excellent short-term or “working” memories that allow them to remember where their loved ones are within a room or house for at least 2 minutes (1). However, when it comes to long-term memory, dogs rely more on associations and emotional connections rather than specific details like humans do.

While dogs may not remember every detail about a previous owner years later, they can still form powerful bonds and impressions that last over time. Their sense of smell in particular triggers memories and associations with people, places, and experiences (2). So a dog is likely to remember a previous owner through their distinct scent and through positive associations of love, fun, and comfort they felt with that person.

Studies also show dogs can recognize familiar faces even after years of separation. So they may not remember specifics about their previous family, but they can still recognize those people visually if reunited (3). The strength of their memory depends on how strongly they were bonded with a previous owner and the positive experiences imprinted.

Puppy Imprinting Stage

The imprinting stage in puppies typically occurs between 7-16 weeks old when they are most receptive to forming social attachments. During this time, puppies imprint on their human caretakers, meaning they form a strong bond and view them as a source of comfort and security. This imprinting shapes the puppy’s future behaviors and emotional responses.

Studies show that the more positive contact and caretaking a puppy receives from a human during this imprinting stage, the more attached and loyal they become later in life. Puppies that are frequently handled, played with, spoken to, and cared for by a main caretaker are more likely to view that person as their “parental figure.” This imprinted bond can last a lifetime.

The imprinting period only happens once but has long-lasting effects. An imprinted puppy is more confident, less stressed in new situations, and more inclined to obey commands from their imprinted person. Imprinted dogs often show preference for and excitement around the person they first bonded with.

While imprinting mainly happens in the critical puppy period, dogs can form strong attachments later in life as well through consistent positive interactions. However, the imprinting stage represents a unique opportunity to shape a puppy’s emotional wiring and relationships with humans. The care and attention provided during this time is crucial in forming a deep, lasting bond.

Scent Memory

Dogs have an incredibly strong sense of smell that allows them to develop powerful scent memories. Their noses have up to 300 million odor receptors compared to humans’ 5 million. Studies show dogs can remember and distinguish scents even years later. Anecdotal stories abound of dogs recognizing previous owners simply by their smell long after being separated.

One scientific study found dogs could identify the scent of a person they hadn’t encountered in over two years ( Owners often report when they visit a shelter dog later adopted by someone else, the dog seems to remember them through their scent. There are many stories of dogs whimpering, jumping, and showing other signs of recognition when smelling a previous owner or item with their scent, even after months apart.

A dog’s powerful sense of smell likely allows them to form enduring scent memories of owners and people close to them. Even if separated for long periods, smells can trigger recognition and excitement in dogs when reunited with an old family member.

Visual & Auditory Cues

Dogs can remember visual and auditory cues associated with previous owners for many years. A 2016 study by the Department of Psychology at Emory University showed that dogs’ brains respond differently to the faces and voices of familiar humans versus unfamiliar ones, even if they have not seen that person for a long time. Specifically, certain regions of the dog’s brain showed significantly more activity when exposed to cues from a previous caregiver compared to someone unfamiliar, indicating recognition and recall [1].

This means dogs are able to remember the faces and voices of those they bonded with in the past through imprinting or regular contact. So even years later, they may recognize and respond to a previous owner based on visual cues like their face or body shape, auditory cues like their voice or laugh, and olfactory cues relating to smell. While forming a new bond, owners should be understanding if their dog occasionally seems distracted by familiar sights, sounds or scents relating to their past.

Regression Behavior

Some dogs may exhibit regressive behavior when they reunite with a previous owner after being separated for an extended period. This type of behavior regression is often a result of the dog feeling confused or conflicted between their old and new living situations.

According to the ASPCA, older dogs in particular may display regressive behaviors such as whining, pacing, loss of housetraining, and following their owner around the house constantly. This regressive behavior can be triggered by major changes to the dog’s routine or environment, such as reuniting with a previous family.

The sudden shift back to an old home and family can cause the dog to revert to puppy-like behaviors they haven’t displayed in years. While eager to reconnect with previous owners, they may also grieve the loss of their newer home. This conflicting emotion can result in clingy, velcro dog behavior, territorial marking, and other regressive conduct.

With patience and by establishing structure through set routines, dogs usually adapt to the reunion after an adjustment period. Keeping interactions low-key, providing familiar toys and beds, and maintaining regular schedules can help create stability. Consult an animal behaviorist if regressive behaviors persist or severely impact quality of life.

Preventing Runaways

There are several tips new adopters can follow to discourage a recently adopted dog from trying to run back to their previous home:

Take the dog on regular walks in the new neighborhood right away so they can get accustomed to the sights and smells (MaxFund). Bring tasty treats and make it a positive experience.

Keep doors and gates securely closed and monitor the dog when outside in the yard until they adjust to their new home. Consider installing secure fencing if needed (Tractive).

Provide plenty of chew toys, puzzles, and activities to prevent boredom and keep the dog engaged in their new environment.

Maintain a consistent daily routine with regular feeding times, walks, playtime and affection. This helps the dog feel secure as they transition.

Ask the previous owners for a worn blanket or t-shirt with familiar scents. Place it in the dog’s bed or crate to provide comfort.

Use pheromone diffusers and calming supplements if the dog seems anxious. Consult with a vet or trainer if escape attempts persist.

Forming a New Bond

When adopting a rescue dog, it’s important to form a strong bond to help the dog feel secure in their new home. Here are some tips for adopters on bonding with a rescue dog:

Keep a consistent daily routine. Dogs thrive on predictability, so adhering to a regular schedule for feeding, walking, playing, etc. can help a rescue dog settle in. Make sure everyone in the household participates in the routine [1].

Engage in positive training techniques such as clicker training. Working cooperatively on commands and tricks is a great way to build a bond through mutual understanding and respect [2].

Incorporate playtime and physical affection. Games, toys and gentle petting help reinforce the positive association between adopter and dog. Focus on what the dog enjoys most [3].

Be patient and let the dog warm up to you. Don’t force interactions. Allow the dog to initiate contact and approach you when ready. This establishes trust in the relationship.

Make sure the dog has their own safe space, bed and belongings. This sense of stability and ownership aids bonding.

When to Be Concerned

Some common signs that a dog is having trouble adjusting to a new home include separation anxiety, regression in house training, destructive behaviors, appetite changes, fearfulness, and aggression. Separation anxiety can manifest as barking, howling, whining, panting, pacing, and even self-injury when left alone. Regression in house training like urinating or defecating indoors may indicate insecurity and stress. Destructive chewing, digging, or scratching behaviors point to boredom, anxiety, or frustration. Appetite changes ranging from disinterest in food to overeating can signify depression or stress. Increased fearfulness like cowering, shaking, or hiding are signs your dog is overwhelmed. Lastly, any aggression like growling, snapping, or biting is a red flag your dog is feeling insecure or threatened in the new environment.

If your newly adopted dog displays any of these behaviors, especially in the first few weeks after adoption, it likely indicates they are struggling with the adjustment. Remain patient and compassionate while implementing structured routines and positive reinforcement training to help build confidence and security. Consider consulting with a veterinarian or certified dog behaviorist if problems persist beyond the initial transition period.

Providing Closure

Giving dogs closure after leaving an old family can help ease the transition to a new home. Some strategies for providing closure include:

Take the dog back for a final visit if possible. Letting the dog see the old family one last time allows for a proper goodbye. Be sure to keep interactions positive and avoid creating further confusion. [1]

Leave familiar toys or bedding with the old family’s scent. Having a familiar scent from the previous home can provide some comfort. Introduce new toys and bedding gradually. [2]

Ask the previous owners for photos. Looking at photos of the old family from time to time can give the dog a sense of closure. Be sure to spend ample quality time together to strengthen your new bond.

Maintain a predictable routine. Sticking to a regular schedule of feeding, walking, playing, and bonding helps provide stability. Be patient and understanding during this transition period.
