Whether you're physically interacting with another dog or come home after being around one, your dog's jealousy stems from their loyalty to you, whom they consider to be their pack leader.
If your dog is having a positive experience, they will almost always maintain positive body language around another dog. Positive body language includes long and high, side-to-side tail wagging, play bowing, a loose opened mouth, a low, relaxed tail, or soft or squinted eyes.
The most common symptoms of inter-dog aggression include growling, biting, lip lifting, snapping, and lunging toward another dog.
Dogs are inherently social animals that live well together in groups, but that does not mean that all dogs get along. Most dogs will welcome a new sibling, but it is not always smooth sailing. The furry family member you have now will face many changes when a new dog enters the picture and may feel a bit displaced.
Experts agree that dogs get lonely when they spend much of their time alone because they are pack animals. Descended from wolves, who live and work in groups, dogs are social beings, and we have become their pack members. If they are deprived of companions—both canine and human—they suffer.
Second Dog Syndrome
As humans, we are bound to forget all of the time and effort it takes to raise a puppy right. All too often, a second dog joins the household and the expectation is that they will behave as the existing dog in the home does, so they are often given the same freedom right off the bat.
Experts believe that the best time to add a second dog is in the first 2 to 3 years of age of the first dog. Some have found that older dogs are not as excited about adding a young energetic puppy to the family. However, it is a total case-by-case basis for your dog and particular circumstances.
A jealous dog may attack another pet that gets too close to you. He'll try to push another pet away so he can get your attention. He's afraid of losing your love and attention.
Signs of jealousy
Your pup may tell you they're jealous by: Barking or whining for your attention. Growling or snapping at the interloper. Getting between you and other people or pets or pushing them away.
Bringing home a new puppy or another adult dog can trigger jealousy in your dog, and they may show signs of aggression toward the new addition. Your dog might growl at the new dog, guard your lap, or try to get in between you and your new furry family member.
Is a Dog More Protective of Female Keepers? This isn't a general rule, but some pets are more likely to exhibit protective behavior with female keepers. This is because women generally have a softer voice and are gentler whenever they care for the dog.
Methods such as alpha rolls and physical corrections (via the leash and a choke chain or by smacking the dog on the nose or by shaking their scruffs) were often recommended as a way for humans to establish dominance over their dogs.
"The goal is to teach the dog that it will receive a favored treat or reward that is even more appealing than the object in its possession." Approaching calmly, offering a food reward and taking the possession, praising the puppy and returning the object teaches the puppy that your actions are not to be feared.
By nature, dogs are social and thrive in group environments. Therefore, there are many advantages to adopting a second dog, such as: They can keep each other company. Both dogs will be able to entertain each other and get exercise together.
Most dogs need at least 1-2 walks per day (unless otherwise specified by your vet). A brisk walk is a great opportunity for your dog to burn off extra energy, and a slow, meandering walk – where you let your dog sniff and explore for as long as they want – is great for their mental health.
Some dogs don't need anything to find themselves running around the house and playing with their toys, others will snooze through a jackhammer no sweat. If you're working from home right now you might see your pet sleeps all day even with you right next to them! Dogs, like people, are unique.
Experts recommend adopting a dog of the opposite sex if you add a second dog. While you should consider the gender of the second dog when adopting another dog, it's not the only thing that matters.
It may take several weeks for the two dogs to get used to each other, so patience is required. But most of the time, dogs are accepting of other dogs, often welcoming the companionship. It's just a matter of an owner setting expectations and being consistent.
