Your older dog is likely afraid of a new puppy due to the puppy's unpredictable energy, feeling of displacement, fear of the unknown, or potential physical discomfort from the puppy's boisterous play, requiring slow introductions, a safe space, maintaining routines, and positive reinforcement to help them adjust. It's normal for older dogs to feel overwhelmed by a puppy's high energy and need time to establish boundaries.
Your dog may act like they hate puppies, but that's not necessarily what's going on. There are a number of reasons an older dog might not want to deal with a puppy, from their inability to read social and physical cues to the relentless invasion of your adult dog's personal space.
The 777 Puppy Rule (or Rule of 7s) is a guideline for puppy socialization, suggesting that by seven weeks old, a puppy should experience seven different Surfaces, seven different Sounds, seven different Objects, seven different People, seven different Locations, seven different Containers, and seven different Challenges, all in positive, short, and safe ways to build confidence and resilience. It helps prevent fear and reactivity by creating positive associations with novel experiences during the critical socialization window (around 4-16 weeks).
It varies, but generally, it may take a few weeks for your older dog to adjust to the new puppy. Some dogs bond quickly, while others may take longer.
If your adult dog growls at your puppy or shows other signs of discomfort such as lunging or snapping, encourage your puppy to move away from your dog and give them something fun to do in their own safe space. If your puppy has been injured, seek veterinary advice straight away.
Never Punish Your Pooch
If your older dog growls at the puppy, leave them be for a moment and try and reassure them both that all is well. If the growling continues, remove the puppy and put them in another room, then return to your older dog and give them more reassurance that everything is OK.
The 3-Bark Rule is a dog training technique that lets a dog bark up to three times to alert to a perceived threat (like someone at the door) and then teaches them to stop with a "quiet" or "done" cue, respecting their natural watchdog instinct while preventing excessive barking. It involves acknowledging their alert (sometimes with a "thank you"), letting them bark a few times, and then calmly asking them to stop, rewarding them when they do.
The 3-3-3 rule for dogs is a guideline for the adjustment period after adoption, outlining three phases: 3 Days (decompression, feeling overwhelmed/scared), 3 Weeks (starting to settle in, learning routine, personality emerges), and 3 Months (feeling secure, bonded, and truly at home). It helps new owners manage expectations and be patient as their rescue dog transitions, emphasizing calm energy, routine, and space in the early days to build trust.
The Hardest Dog Breeds to Train: Working with Difficult to Train...
HELP! My older dog doesn't like my puppy!
Red flag puppy behaviors signal serious issues beyond normal puppy antics, including aggression (growling, snapping, biting, lunging), extreme fear/anxiety (intense cowering, hiding, refusing treats, constant escape attempts, shutting down), resource guarding (guarding food/toys with aggression), and severe separation anxiety (destructive behavior when alone). Recognizing these early and seeking professional help from a trainer or vet is crucial, as these often stem from trauma or lack of socialization and won't just disappear with age.
The hardest months with a puppy often center around two key periods: 3-5 months (teething, regression, lack of impulse control) and 6-12 months (adolescence), when hormone surges bring boundary testing, stubbornness, and increased energy, making training and housebreaking challenging as they become "teenagers". Expect frustration with accidents, nipping, chewing, and defiance during these phases as their brains develop, requiring patience and consistent training.
The 10-10-10 rule for puppy potty training is a specific routine: 10 minutes outside in the designated potty spot, staying 10 feet away from the house/play area, followed by 10 minutes of focused supervision indoors to prevent accidents before the next potty break, creating a consistent cycle for success. This method ensures the puppy has ample time to eliminate and minimizes mistakes by closely monitoring them afterward, reinforcing good habits consistently.
You can tell if a dog is sad by noticing changes in behavior, body language, and energy, such as lethargy, loss of appetite, hiding, lack of interest in play, a low or tucked tail, flattened ears, excessive licking/pacing, or increased inappropriate urination, all signaling potential depression or unhappiness that often requires a vet visit to rule out medical issues.
Whenever you introduce a new puppy to a dog, there's a chance they may feel put out at first and demonstrate jealous behaviour. Over time, dogs develop close bonds with their owners.
Set a timer on your phone, let them play for a few minutes, and before it gets heated, ideally even before the older dog shows any signs of tiring, separate them. Leave them both wanting more. At some point, the puppy will either mature out of this phase or internalize the timer.
Some of the most common include:
The "heartbreak breed" refers primarily to the Great Dane, nicknamed this due to their affectionate nature combined with a relatively short lifespan (around 7-10 years) and susceptibility to serious heart conditions like dilated cardiomyopathy (DCM), making losing them particularly difficult for their devoted owners. Other giant breeds like Irish Wolfhounds, Bernese Mountain Dogs, and Saint Bernards also face significant health challenges, including cancer and heart disease, often earning them similar sentiments from owners.
10 Dog Breeds That Can Be Difficult to Train
The most commonly surrendered dog type is the "pit bull type" (including mixes), often due to negative stereotypes, breed-specific legislation, and high energy levels, followed by other popular breeds like German Shepherds, Huskies, and Labrador Retrievers that may not fit owner lifestyles. Breeds like Staffordshire Bull Terriers (especially mixes) also top surrender lists in some regions like Australia.
The seven second rule. Put the back of your hand on the pavement. If you cannot hold it for seven seconds, it is too hot to walk for your dogs. This rule also applies to dogs riding in the bed of a pickup truck.
For most pets, it takes on average 3 months to fully become comfortable and acclimated to their new home. However, some pets may need longer to adjust, and some may adapt more quickly.
A red flag dog behavior signals deep fear, stress, or potential aggression, going beyond normal misbehavior, and includes intense growling/snapping without cause, sudden aggression in a calm dog, persistent hiding, resource guarding (food aggression), freezing, destructive behavior linked to separation anxiety, or signs of extreme anxiety like trembling, lip-licking, and tail-tucking, indicating underlying problems needing professional intervention.
Gradually move farther away from your dog, allowing them to bark but then giving the “quiet” command and offering the treat to them so they can see it. Step 11: Now stand or sit across the room from your dog, without any treats visible, and allow your dog to bark and then give the “quiet” command.
