For the happiest dogs and the safest household, opposite sex dogs almost always do best together. Many same-sex combinations of dogs will fight, sometimes to the death. Those who work out a dominance order may not fare much better.
In some cases, two dogs of the same sex may get along fine, but some experts feel it is best to choose a new pup of the opposite sex. Same sex dogs may become rivals, and there is a greater chance of competition among the two. If you want to play it safe, team your female dog with a male counterpart and vice versa.
Keep both dogs on their leashes and allow them to sniff each other and touch noses for a few minutes, then separate them and do something to distract them, such as playing or practicing some obedience training. Bring them back together to repeat the sniffing.
Dogs are social animals and usually happier around other dogs, but a second dog will never be a substitute for inattentive, absent or too busy owners.
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.
Most experts agree that, as a rule, male and female dogs get along better than two females or two males.
Many breeders recommend that your first dog be at least one-to-two-years old before you add a second to the family. If you have an old dog, he may not be physically able to play with or tolerate a pup.
Gender: While there is no set rule that a female dog will be a better friend for a male dog, if you have never had two dogs at the same time it is generally easier and often safer to have dogs of the opposite sex. Same-sex combinations can be tricky to manage as dogs work out their dominance or pack order.
Many people are hesitant to adopt a second dog because they assume it will be twice the work and twice the money. But the truth is, owning two dogs doesn't have to be more work – in fact, it can often be easier. And as for the cost, it will cost more money than one but not twice the amount.
Touching is a sign that animals not only get along well but also that they trust one another, said Nelson. "If they are sleeping with each other and snuggled up together — really truly making contact with each other — then that's an obvious sign that there's true affection between the animals," Nelson explained.
It can take up to one month for an old dog and new dog to really settle in and accept each other's position in the pack. If you want a second dog, you need to be ready to commit to this process and not panic.
Inter-dog aggression often focuses on issues of social status and control, which become apparent at social maturity (approximately 18 to 36 months of age in dogs). Inter-dog aggression can occur between dogs that are either unknown or known to each other.
Can dogs live together after fighting? The answer is, most of the time, YES. There are times when dogs may be like an incompatible couple and need to divorce, but in general, there are things you can do to help combative pups get along.
Introduction of a New Pet
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.
In dogdom, there's a turn of phrase called, "Second Dog Syndrome". This describes the process of adding another dog to the home quite well, but not necessarily in a positive light. As humans, we are bound to forget all of the time and effort it takes to raise a puppy right.
Other pets might bring some comfort to your anxious dog, but they won't cure their separation anxiety. Unfortunately, the short answer to the question “Will getting another dog help my dog with separation anxiety”, is usually no.
Having a multi-dog home can be great, but it's not for everyone or every dog. Many dogs thrive in a home with other pups, but not all can adjust. For example, if your dog isn't comfortable around other dogs, bringing home another puppy might not be the best choice.
Fast Friends, or Not. You can help dogs avoid conflict and make good connections by doing these two things: Give each dog its own food bowl and eating space, water bowl, bed or sleeping area, and plenty of rest. Continue walks together and other fun activities.
Meyer. One of the most important rules of dog training is the two second rule. This is because dogs always live in the moment so TIMING IS EVERYTHING! Feedback must be given to your dog within two seconds of the behavior in order for him to understand what you are correcting or rewarding.
The Consequences of Adding a Second Dog to Your Home
Getting a second dog could make your first dog feel displaced and uncertain. While the majority of dogs will get along well with their new sibling, your first dog may not be happy having to share their toys, space, territory, or even their owner's affection.
It's good to have a friend
Dr. Zazie Todd, author of Wag: The Science of Making Your Dog Happy, says these dogs “will benefit from having another dog in the house because it gives them more opportunities to engage in normal canine behaviors” like play.
