Dogs are just like us. Some dogs can become fast friends within a few hours, but some dogs may never get along. It could be due to clash in personalities. Some dogs may be active and lively ,while the others may be quiet and antisocial.
Many people do not give two dogs time to adequately adjust to one another before deciding that having two dogs will simply not work. 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.
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.
Usually, grown dogs will accept a new younger dog. But to successfully add a second dog to your family, you must take the time and follow the proper steps to introduce a puppy to an adult dog. Some older dogs will make joining their pack difficult for the newbie!
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.
“Feed the dogs separately and always pick up the bowls. Additionally, they should never have treats unless they're apart. Toys can also be a cause of aggression.” Adopting a new dog or puppy can upset your pack's pecking order, and it'll take some time for things to decompress as the newcomer settles in.
While it seems dogs do forgive after a fight, there's still a lot more to learn about reconciliation in dogs. In some multi-dog households, it doesn't always work out. Shyan-Norwalt has observed dogs in the same family who did not reconcile but instead separated after every conflict.
Sometimes, two dogs cannot live together after fighting. This doesn't necessarily mean you need to rehome them, but it does mean keeping them separated for the rest of their lives. As we discussed above, you'd need to crate and rotate (using either literal crates or rooms) or split your house into two parts.
Some have recommended that the dogs not be anywhere near one another for at least 48 hours following the fight, even if they live in the same household, while others recommend that getting a positive interaction between the two animals as soon as possible is the best course of action -- at the end of the day, however, ...
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, they may not be physically able to play with or tolerate a pup.
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. This makes it important to prepare and do your research when getting ready to bring home a second dog.
Many common behavioral concerns, including fear, anxiety, and frustration-related behaviors, become more evident at social maturity and can underly an overly aggressive response. The younger dog may be initiating confrontations to gain access to resources, though that is just one possible trigger.
Unfortunately, some fighting dogs will not stop fighting until an injury occurs that results in one dog backing off. However, some triggers are easily identified and can be avoided. Multiple dogs of the same sex that live in the same house (all female or all male) may be at a higher risk of fighting.
Introduce on neutral territory.
At first, walk the dogs at a distance where they can see each other but are not too provoked by each other's presence. If the dogs are not showing any negative behaviors, reward them with treats just for seeing each other.
The (sort of) good news is that all these feelings are common. Type “second-dog guilt” into Google, and you'll see how many people feel conflicted about adding another dog to the pack. So though it doesn't necessarily feel good to feel this way, at least there's safety in numbers.
Dog behavior changes with age, but it is a gradual process. For example, a 2 year old dog behavior change is a common milestone, which is the age many dogs reach adulthood. Later on, some senior dogs may display irritability due to things like arthritis pain or loss of vision.
In general, it may take around 4 to 8 weeks for resident dogs to get used to the change associated with a new addition, but it can take up to 6 to 9 months for both dogs bond and feel comfortable around each other.
