Here are some easy ways to stop your dog from growling at strangers

Expert-approved steps to teach your dog to stop growling at strangers

When we feel afraid, uncomfortable, or even cranky, we have words to express how we feel. Dogs, on the other hand, have vocalizations and body language (as well as scent) to help them understand one another. This is how they communicate with people, too, so it’s important that pet parents learn how to interpret their fur baby’s sounds — including your dog's growling.

Why does my dog growl at strangers?

Not all cases of growling are negative; dogs often growl during play or while getting belly rubs, for example. However, you're less likely to see these “happy” growls if your pup is interacting with strangers — unless they’ve become fast friends, of course.

Most likely, notes Purina, your dog will let out either a frustrated, warning, or aggressive growl if approached too quickly by a stranger. A warning growl will sound like a deep rumbling and is not meant to indicate an attack. It’s simply a way of saying, “Please back off!” So make sure to take action before your dog gets more uncomfortable.

Frustrated and aggressive growls will sound “long, loud, and low” according to the folks at Purina. Aggressive growls are often accompanied by hackles (the hair on the back of the neck) raising. Dogs who make this sound feel threatened, and they will let you know.

You may see lunging movements, whereas frustrated dogs may run back and forth, as if anxious. A dog who barks out of frustration may actually want to get closer to say hello, though you should double-check with the person (and pet!) they want to meet before moving forward.

How to stop your dog from growling

Once you’ve identified the reason(s) for your dog’s reaction, you can work on exposing your pet to their trigger — in this case, strangers — in a new, safe way.

The American Kennel Club (AKC) recommends a combination of desensitization (gradually spending more and more time around strangers) and counter-conditioning (changing how your pup feels about strangers) training to make habit changes effective. Not only will this help your dog get used to being around humans, but they’ll truly enjoy it too.

It’s important to keep your dog calm throughout any training sessions, as adding stress will make them ineffective. After all, the idea is to show them that friendly strangers are great!

Step 1: You will need to enlist the help of a friend your fur baby hasn’t met, as well as a lot of treats.

According to the AKC, the very first step is to reward your pup for simply remaining calm in the presence of a stranger, whether they’re comfortable a few feet away or across the dog park. Make sure to reward them immediately after they notice the stranger so they can begin to make a mental association between the new person and the treat.

Step 2: Walk your dog away and then back toward the stranger to repeat this reward process.

Once your puppy begins to expect a treat, they are calm enough to move forward in training.

Step 3: Now you can get a little closer to the stranger and reward your pup just like before.

Step 4: Continue this process until your dog is comfortable at that distance, and then repeat at a closer and closer distance.

This repetitive process will let you move your dog slowly but surely toward the person until that new friend is handing your dog the treats themselves. Of course, this should all go at your dog’s own pace. If they ever seem stressed out, it’s a good idea to move back a step or two for now.

Example desensitization process

Here’s a sample of steps this process can take, courtesy of the AKC:

Step 1: When your dog is within 2 feet of the stranger, hand the dog a treat and have the stranger toss one to them as well.

Step 2: Repeat this process at 1 foot away and then when the dog is next to the stranger.

Step 3: Let your dog approach the stranger and take a treat from the ground at the stranger’s feet

Step 4: Next time, offer a treat directly from the stranger’s hand.

Step 5: As the stranger hand feeds the treat, have them gently pet the dog’s head, back, and/or chest--once the dog seems comfortable enough.

The stranger should reward the dog with another treat for being calm and cooperative.

Step 6: Gradually, the stranger should increase the amount of contact before feeding the treat.

With enough patience and love (and treats), baby steps like these will take your dog’s training further than you ever imagined. Of course, it also helps when the folks your dog interacts with know how to approach them in a friendly manner. Whether they’re helping you or you’re helping train their dog, remember: never lean over a dog or stare into their eyes, as this can be threatening. Instead, kneeling down and turning to the side is non-aggressive body language that makes dogs feel more comfortable.

While there’s no question that dogs and loyalty go hand in hand, small dogs are more often known for their sass. It’s not hard to picture an ankle-biter barking up a storm at any bigger dog who walks by, but when it comes to their people, these pint-sized pups couldn’t be more loyal. Whether this loyalty looks more like affection, protection, or just being nearby depends on the breed and the individual dog, so it’s worth considering what you’re truly looking for before you adopt a certain breed of dog. With any of the breeds on this list, though, you can’t go wrong.
These are the seven most loyal small dog breeds — ranked in order of loyalty. Of course, this came down to our research and beliefs, so you may have a different opinion. We'd love to know what you think--which do you think are the most loyal small dog breeds?

Shih tzus are lap dogs through and through -- they are the definition of loyalty
Shih tzus were bred to be companion dogs in Tibetan monasteries, in case you couldn't tell from their clingy personality. When you bring one of these affectionate pups into your home, explains Dr. Marty Goldstein, you’re signing up for one of the closest bonds you’ll ever make. They’ll be happy as your “Velcro dogs” no matter what you’re up to, and with their curious yet calm personalities, you’ll be happy to include them. Loyalty is just one reason to love this adorable, ancient breed.

Why is my dog drooling? Here’s when to be concerned about sudden or excessive dog salivation
This is why your dog slobbers all over you and themselves

Although St. Bernards, Mastiffs, and several other large breeds are known for their tendency to drool, it may be quite a shock if your usually drool-free pup suddenly starts to salivate. Luckily, you’ve come to the right place if you find yourself asking, "Why is my dog drooling?"
We’ve looked into many causes of excessive and sudden salivation, from the easy fixes to the more concerning problems. Most likely, drooling is nothing to worry about, but it never hurts to take a more careful look — especially if your pup is behaving oddly. Here’s everything you’ll want to know about canine salivation.

Why is my dog drooling and is sudden or excessive drooling a cause for concern?
Though drooling has many harmless causes, which we'll cover later in this article, you may want to keep a closer eye on your pet if you notice sudden salivation — especially if it’s a large amount.
Nausea and stomachaches are common causes of sudden drooling for dogs, although they will be temporary. If you think about it, many humans experience the very same thing! You may also notice vomiting or lethargy if your pet has ingested something they’re not supposed to, so don’t hesitate to contact your veterinarian if you’re concerned about your best buddy’s wellbeing.
On a more urgent note, dogs may also salivate if a foreign object becomes lodged anywhere in the mouth or throat. This can become a dangerous situation if the object blocks their airways, so you should waste no time in getting your fur baby to your closest veterinarian’s office if this could be the case.
Excessive, sudden drooling can also occur when a dog is overheated. Ashely Gallagher, DVM, explains that although salivation can act as a way of cooling off, just like panting, dogs don’t usually resort to this technique unless they are having trouble regulating their temperature through panting alone.
One last cause of sudden drooling is an upper respiratory infection. An illness of the nose, throat, or sinuses is more likely for pups who have been in group settings, such as shelters or kennels, but any dog can catch one, according to Amy Flowers, DVM. Luckily, your veterinarian will be able to guide you toward the best treatment for your furry friend. In most cases, it's a quick fix!
